Physical, mechanical and abrasive wear behaviour of jute fiber reinforced polymer composites

Physical, mechanical and abrasive wear behaviour of jute fiber reinforced polymer composites

mechanical, chemical and thermal properties, has been categorized into mild and sever wear [165]. A lot of research has been made on the wear behaviour of jute fiber reinforced polymer composites. Dwivedi and Chand [166] studied the impact of fiber orientation on the friction and sliding wear performance of jute fiber reinforced polyester composites. Different fiber orientation in the composite namely LL, LT and TT with respect to sliding direction were taken for wear study. The maximum wear resistance was observed in case of TT sample and minimum in case of LL sample. The coefficient of friction was highest for TT sample and lowest for LT sample. Micro-cracking, micro-pitting and debonding were responsible wear mechanisms under sliding wear mode in jute-polyester composites. Chand and Dwivedi [167] investigated two body abrasive wear behaviour of chopped jute- polypropylene composites to understand the effect of coupling agent i.e. maleic anhydride-grafted-polypropylene (MA-g-PP) on composites during abrasion. It was found that coupling agent results in improved wear resistance compared to untreated composites (UT). The MA-g-PP melt-mixed jute fiber reinforced PP composites offered better wear resistance than the MA-g-PP solution-treated jute fiber reinforced PP composites. From the study it was also observed that wear volume increased with increase in sliding distance for all the composites. Experimental investigation also revealed that wear rate increased with increase of normal load.

Mechanical and wear behaviour of pulverised poultry eggshell/sisal fiber hybrid reinforced epoxy composites

Due to environmental pollution and petroleum depletion, development of composites using natural fibers has been given great attention from scientists and researchers globally recently (Faruk et al 2014, Dinesh et al 2019). Natural fibers such as sisal and kenaf have been successfully applied in both thermoplastic and thermosets matrices ( Jeencham et al 2014, Fiore et al 2015 ) . Natural fi bres and particles are used as reinforcement in polymer matrix composites due to their abundant availability, ease of manufacturing and being less aggressive to manufacturing tools, sustainability and biodegradability compared to the synthetic fi bres ( Ahmad et al 2015, Daramola et al 2019). Automobile industries also find the need to lower fuel consumption by lowering the weight of automobiles and reducing dependency on non-renewable resources, such as petroleum based polymers and to source for their replacement by using natural materials which has little or no effect in the environment. Also, hybrid composites from synthetic and natural reinforcements have been developed immensely but not much has been done in the area of using the blend of animal waste with vegetable fi bres.

VIBRATIONAL BEHAVIOUR OF SANDWICH PLATE WITH CORE AS JUTE REINFORCED POLYMER MATRIX COMPOSITES

VIBRATIONAL BEHAVIOUR OF SANDWICH PLATE WITH CORE AS JUTE REINFORCED POLYMER MATRIX COMPOSITES

From the last few years, Jute fibers are being looked at as an alternative reinforcement material in the development of composites in a variety of engineering fields. Jute fiber has some exceptional properties such as bio-degradability, low cost, moderate mechanical properties. These properties along with its easy availability have made it suitable to use as a reinforcement material in the ongoing development of composite containing polymer matrix. Hence, Jute fibers can replace commonly used synthetic fiber along the lines of Kevlar, glass fiber etc., in composite material. Also, matrix used here is hybrid polymer matrix which is a mixture of Cashew Nut Shell Liquid and General Purpose Resin instead of pure synthetic matrix. This combination of reinforced composite can be utilized in diverse engineering applications. In this work, Jute fiber reinforced Hybrid resin (CNSL and GP) composites are fabricated by using hand lay up technique. Volume percentage of jute fiber in reinforcement (3%, 6%, 9%), specimen thickness (2mm, 3mm, 4mm) and fiber length (30mm, 100mm, 350mm) are the parameters varied in the respective mold dimensions. The experimental plan was developed according to TAGUCHI’s Design of Experiments. The testing is performed using cantilever fixture. By applying impact, the response of the system is analyzed by utilizing “DEWEsoft” software. Using the ANNOVA technique, influence of different vibration frequencies was investigated.

MECHANICAL BEHAVIOUR OF SHORT SISAL FIBER REINFORCED POLYMER COMPOSITE

MECHANICAL BEHAVIOUR OF SHORT SISAL FIBER REINFORCED POLYMER COMPOSITE

The demand for wood increasing steadily from day to day, has led to the development of alternate materials. After various researches in synthetic materials researchers has found out that polymer composites can be used as an alternate of wood. From the recent past years, there is an increasing interest in using natural fibers (Sisal, Jute, Hemp, Flax, Bamboo etc) for reinforcement with polymer composites. This is because these natural fibers are available in plenty in many countries. Among these fibers, Sisal fiber has high impact strength, and moderate tensile properties and flexural properties compared to most other fibers. In this paper the mechanical properties of short sisal fiber (5mm) reinforced polymer composites has been investigated.

Comparative Study Of Physical And Elastic Properties Of Jute And Glass Fiber Reinforced LDPE Composites

Polymeric technology is one of the most active and promising fields that covers natural polymers such as cellulose, wool, silk, jute, palm fiber etc which are of outmost importance for living systems. The science of macromolecules is divided into two classes: biological and a non-biological materials. Non-biological are the synthetic materials used for plastics, fibers and elastomers with a few naturally occurring polymers such as rubber, wool, and cellulose [5]. In the present era of polymeric science is the most promising and comprehensive field. Development of new polymer is a continuous process for a specific application under certain environmental conditions. The bombardment of the invention of different polymer field has been found to be increased day by day. Biodegradable polymeric materials are enjoying considerable popularity, especially from the standpoint of environmental protection [6]. Fiber reinforced composites are widely used because of their some extraordinary properties such as good processability, relatively good resistance, high stiffness, ease of installation to environmental agent etc. Synthetic fiber reinforced thermo plastic composites are dominating the composite market due to their better durability and moisture resistance properties. Among all the reinforcement materials, glass fiber attracted much attention owing to their improved physical, elastic and mechanical properties, good corrosion resistance, and sound absorption and insulation properties. A well known glass fiber is E-glass which has good insulation properties. Glass fibers are normally used as mats, insulator, reinforcement, sound absorption, heat resistant fabrics, corrosion resistant fabrics and high strength fabrics [7-8]. In recent

A Review on Mechanical Properties of Natural Fiber Reinforced Hybrid Polymer Composites

A Review on Mechanical Properties of Natural Fiber Reinforced Hybrid Polymer Composites

Natural fibres will take a major role in the emerging “green” economy based on energy efficiency, the use of renewable materials in polymer products, industrial processes that reduce carbon emissions and recyclable materials that minimize waste. Natural fibres are a kind of renewable resources, which have been renewed by nature and human ingenuity for thousands of years. They are also carbon neutral; they absorb the equal amount of carbon dioxide they produce. These fi- bers are completely renewable, environmental friendly, high specific strength, non-abrasive, low cost, and bio-degradability. Due to these characteristics, natural fibers have recently become at- tractive to researchers and scientists as an alternative method for fibers reinforced composites. This review paper summarized the history of natural fibers and its applications. Also, this paper focused on different properties of natural fibers (such as hemp, jute, bamboo and sisal) and its ap- plications which were used to substitute glass fiber.

Fabrication and Investigation of Mechanical Properties of Sisal, Jute & Okra Natural Fiber Reinforced Hybrid Polymer Composites

Fabrication and Investigation of Mechanical Properties of Sisal, Jute & Okra Natural Fiber Reinforced Hybrid Polymer Composites

The word “composite” means two or more distinct parts physically bounded together. Thus, a material having two or more distinct constituent materials or phases may be considered a composite material. Fiber-reinforced composite materials consist of fiber of high strength and modulus embedded in or bonded to a matrix with distinct interfaces (boundary) between them. In this form, both fiber and matrix retain their physical and chemical identities, yet they produce a combination of properties that cannot be achieved with either of the constituents acting alone. In general, fiber are the principal load-carrying members, while the surrounding matrix keeps them in the desired location and orientation, acts as a load transfer medium between them, and protects them from environmental damages due to elevated temperatures and humidity. Based on paper “Tensile and flexural properties of sisal/jute hybrid natural fiber composite” which defines that hybrid composite is fabricated by using sisal fiber and jute fiber. By fallowing the composition of mixing of fibers (0/40, 10/30, 20/20, 30/10, 40/0 weight fractions by keeping overall weight fraction as 0.4 weight fraction) gives the fallowing results. Ultimate tensile properties of pure sisal and pure jute are 38.93MPa and 36.93MPa respectively. And flexural properties of pure sisal and pure jute are 87.15MPa and 87.05MPa respectively. At 20/20 ratio (equal ratios of sisal/jute) gives the fallowing results tensile stress is 39.93MPa and flexural stress is 88.33MPa.

Sliding Wear Properties of Jute Fabric Reinforced Polypropylene Composites

Sliding Wear Properties of Jute Fabric Reinforced Polypropylene Composites

Increasing applications of polymeric composites for various mechanical parts including gears, wheels, clutches, bush bearing, and artificial prosthetic joints require adequate knowledge of their tribological properties, which are different from much better understood tribological properties of metals and ceramics. Natural plant fiber reinforced polymer composite components can be applied in many situations for tribological loading conditions. An important part of tribology deals with materials selection and surface processing in as much as they affect wear and tear. A good grasp of interacting surfaces is a must for their optimal functioning, long-term reliability of components and devices, and for economic viability. Work is now in progress to improve the composite’s coefficient of friction and sliding wear, since 90% failure in mechanical parts are as a result of tribological loading [9, 11-15].

A Comparative Study of Mechanical and Physical Properties of Polymer Matrix Composite Reinforced With Bamboo and Jute

A Comparative Study of Mechanical and Physical Properties of Polymer Matrix Composite Reinforced With Bamboo and Jute

Composites materials with light-weight, high strength-to- weight ratio, and stiffness properties are replacing conventional materials like metals, woods, etc. Good Mechanical and Tribological responses of polymer-based composites also support for their application in different areas [1, 2]. The abundant availability of natural fibers such as jute, coir, sisal, pineapple, ramie, bamboo, banana, etc., has given an impetus to the development of natural fiber composites. Composite boards have been used in the development of panel and doors to fulfill the low-cost housing needs. Recent research [3, 4] indicates that natural fibers can very well be used as reinforcement replacing for expensive glass fibers in polymer composites. The study of natural fiber reinforcement is due to its abundant availability in a wide variety [5- 12]. The composites can be prepared with desired properties by orienting the fibers according to the application. The composites are comparatively cheaper to manufacture and there are various manufacturing processes available for the composites. The mechanical properties were evaluated such as flexural strength, tensile strength, impact strength, and tensile modulus, elongation at break, flexural modulus, and hardness of the composites [13].

studied. None of the mechanical properties, excluding the fracture energies show signs of a positive hybrid effect (Marom et al., 1978). Manders and Bader (1981) reported hybrid effect and failure strain enhancement of up to 50% for the glass fiber/carbon fiber/epoxy composite. The failure strain of the carbon phase increased as the relative proportion of carbon fiber was decreases and as the carbon fibers were more finely dispersed. Yerramalli and Waas (2003) have considered carbon/ glass hybrid composite with an overall fiber volume fraction of 30%. Splitting and kinking failures were noted while loading the hybrid laminates under static and dynamic loading rates. Zhang et al. (2012) studied the mechanical behavior of hybrid composites made of carbon/glass reinforcements and the processing method used is ‘wet lay-up’ which is not a best practice for obtaining high quality laminates. An addition of hard reinforcements such as silicon carbide, alumina and titanium carbide improves hardness, strength and wear resistance of the composites (Amar Patnaik et al., 2009; and Chauhan et al., 2009). The introduction of a glass fiber into a polymer matrix produces a composite material that results in an attractive combination of physical and mechanical properties which cannot be obtained with monolithic alloys (Schwartz, 1984). Among the various useful polymer matrices, vinyl ester is typically characterized by properties such as fluidity, corrosion resistance and high strength-weight ratio (Suresha et al., 2007). The advantages of Fiber-reinforced PMCs over traditional materials include greater mechanical strength, lighter weight, better dimensional stability, higher dielectric strength and corrosion resistance and flexibility to improve the

INFLUENCE OF FIBER LENGTH IN THE WEAR BEHAVIOUR OF BORASSUS FRUIT FIBER REINFORCED EPOXY COMPOSITES

The Chand and Dwivedi, 2007 investigated the wear behaviour of jute fiber-reinforced polypropylene composites. Maleic anhydride-grafted polypropylene was added as a coupling agent and found that it gave better wear resistance when compared to the composite without coupling agent. The wear behaviour of kenaf fiberreinforced polyurethane composites was investigated under wet contact conditions by Singh et al, 2011. Better wear performance was recorded when the fiber mat was oriented perpendicular to the sliding direction. The SEM image was used to analyze the wear failure mechanism. Wear behaviour of Bamboo against the free abrasive containing of quartz sand and bentonite was studied on a rotary-disc type wear tester by Tong et al, 1995. It was concluded that the normally oriented fiber composite specimens gave higher wear resistance than the parallel-oriented ones. Mishra and Acharya, 2010 have studied the abrasive wear behavior of bagasse fiber reinforced epoxy composite in three different directions such as parallel orientation (PO) , anti-parallel orientation(APO) and normal orientation(NO) by using a two body abrasion wear tester. They have concluded that the abrasion takes place due microploughing in PO type samples and micro cutting in APO and NO type samples during the wear process.

Mechanical Properties of Jute/E glass Fiber Reinforced Polymer Composites influenced by Hygrothermal Effects

Mechanical Properties of Jute/E glass Fiber Reinforced Polymer Composites influenced by Hygrothermal Effects

Irrespective of nature of material, whether it is a metal or non-metal, it will fail if the conditions are severe-it may be high pressure or high temperature or adverse chemical environment or fields (electric or magnetic) which may cause damage to the material. This phenomenon is common in everyday life, since human beings always drive for weight reduction. They are led to explore light weight structures. As we know generally metals are heavier, there has been an intensive research to find alternative materials such as ceramics and polymers. Even in these two materials, polymers (plastics) are tough competitors to the ceramics as the former is lighter and could easily be fabricated into any kind of complicated shapes at very low temperatures, whereas ceramics need high temperature facilities to manufacture into products. An extensive research on different materials has clearly shown that it is an advantage to have composite materials consisting of two or more constituents (phases) with distinct physical and chemical properties. Therefore we have undertaken to study composite materials based on fiber reinforced composites- Jute fiber reinforced by E-glass fiber. With this background, it is supposed to study involving the composites consisting of FRC’s. Effects of temperature and moisture on Jute/E-glass fibers are studied and micro structural correlation is also formulated.

Three-Body Abrasive Wear Behaviour of Jute-Glass Reinforced Epoxy Composite

Lately, common fiber reinforced with polymer matrix have gotten the consideration worldwide because of their low cost, minimal effort, lightweight, renewability, combustibility ,low density and biodegradability. Very large numbers of natural elements are available which can be used as reinforcement, for example, jute, and banana, rice husk which have turned out to be great and proficient fortifications. Fiber Reinforced Polymer (FRP) composites are known as the most advanced kind of composites. They are exceptionally efficient in terms of their minimal cost, high quality, strength and mechanical properties.

atmosphere, hence provide an advantageous contribution to the global carbon budget. The easy disposal of natural fiber composites is also important, since they can be easily combusted or composted at the end of their product life cycle. Next to the cost benefits compared to synthetic fibers, natural fibers comparably offer high security if used for automotive applications as an example [1]. Additionally, natural fibres have low density and high specific properties. The specific mechanical properties of natural fibres are comparable to those of traditional reinforcements [2-4]. Thus, the intrinsic properties of natural fibres can satisfy the requests of the global market [5] especially for those industries concerned in weight reduction [6]. That is why they can be potential substitute for non-renewable synthetic fibres [7]. However, high moisture absorption, poor wettability and insufficient adhesion between untreated fiber and polymer matrix lead to debonding at fibre-matrix interface [8]. Again, biodegradable fibres need to be reinforced to improve their properties [9-11]. In present study, epoxy, the most common thermoset resin material was used as a polymer for jute and bamboo fibers. The objectives of this study are to determine the physical, mechanical and thermal properties of unidirectional jute and bamboo fiber reinforced epoxy composites.
