Mechanical Properties of Reinforced Banana Fibre / Bio Fibre Hybrid Polymer Composites on Review

Banana is one of the rhizomatous plants and currently grown in 129 countries around the world. India is the largest producer of banana in the world with an estimated annual output of 13.5 million tons, of which 80% is generated from six states, namely, Tamilnadu, Maharashtra, Karnataka, Kerala, Andhra Pradesh and Gujarat. Annually about 1.5 million tons of dry banana fibres could be produced from the outer sheath of pseudo-stem. Different parts of banana trees serve different needs, including fruits as food sources, leaves as food wrapping, and stems for fiber and paper pulp. The abundant availability of natural fibre in India, has been investigated for their use in plastics, including banana fibre , sisal, coir, paper-mulberry, raphia, flax, hemp, jute, kenaf, ramie, papyrus, straw, wood fiber, oil palm, empty fruit bunch, rice husks, wheat, barley, cane (sugar and bamboo), grass reeds, water pennywort, kapok , pineapple leaf fiber and oats and those could be alternately used to reduce the cost of the composites and weight.

Fabrication of Aluminium Reinforced Sugarcane Bagasse Composites and Evaluation of its Mechanical Properties

Fabrication of Aluminium Reinforced Sugarcane Bagasse Composites and Evaluation of its Mechanical Properties

Fiber Metal Laminates (FMLs) are hybrid composite consisting of alternative thin layer of meal plies and fibre reinforced epoxy. The fiber/metal composite technology combines the advantages of metallic materials and fibre reinforced matrix systems. The most widely used metal in fiber metal laminates is aluminium. Aluminium foils and meshes have extremely light in weight, have low density, high strength, excellent corrosion resistance and also cheap. Fiber metal laminates take advantages of metal and fiber- reinforced composites, providing superior mechanical properties to the conventional one. A relatively newer range of composites even employ natural fibers as reinforcements. The interest in natural fiber-reinforced polymer composite materials is rapidly growing both in terms of their industrial applications and fundamental research. They are renewable, cheap, completely or partially recyclable, and biodegradable. Their availability, renewability, low density, and price as well as satisfactory mechanical properties make them an attractive ecological alternative as man-made fibers used for the manufacturing of composites.

Evaluation of Mechanical Properties of Glass-Jute Fibre Reinforced Hybrid Composites

Evaluation of Mechanical Properties of Glass-Jute Fibre Reinforced Hybrid Composites

Hand lay-up technique is the simplest method of composite processing. First, a release gel is sprayed on the mould surface to avoid the sticking of polymer to the surface. Reinforcement in the form of woven mats or chopped strand mats are cut as per the mould size and placed at the surface of mould. The polymer is uniformly spread with the help of brush. Second layer of mat is then placed on the polymer surface and a roller is moved with a mild pressure on the mat- polymer layer to remove any air trapped as well as the excess polymer present. After curing either at room temperature or at some specific temperature, mould is opened and the developed composite part is taken out and further processed.

were removed from the surface. So the bonding between the matrix and fibre was improved. Because of increase in the adhesion the mechanical properties can be increased. The SEM images shows that the with the surface treatment the surface of fibre becomes smooth and the bonding between fibres and matrix increased. Venkata Ramana and Ramprasad[15] studied the impact, tensile strength and flexural strength of carbon/jute hybrid composite. Hand layup technique was used to prepare the composites. Carbon epoxy, jute epoxy and jute-carbon epoxy are the three specimens. The results show that the carbon epoxy having higher tensile strength of 370 Mpa and flexural strength of 11.41 GA. Jute carbon epoxy shows properties 16 times greater than the jute epoxy composite. And jute epoxy shows the higher impact strength of 2 Joules. So by incorporating carbon fibre in the jute epoxy composites the properties are increased. Muktha and Keerthi Gowda [16] investigated fire resistance and water absorption behaviour of polyeater composites reinforced with untreated banana. The results show that with increase in the fibre volume fraction reduces the burning rate and increases the thermal stability. And the water absorption was increases with the fibre volume fraction due to presence of cellulose. By the results natural fibre can be used at where there is less contact with the water and fire. Hari om maurya et.al.[17] studied the mechanical properties of short sisal reinforced epoxy composite 5,10,15 and 20 mm fibres were used. Results show that with increase in the length of fibre impact strength increases found a maximum value of 27.62 kJ/m2 at 20 mm fibre reinforced composites. But there is no change in the tensile strength. 10 mm sisal fibre composites shows

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

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

Glass Fiber Reinforced Polymer (GFRP) is a fiber reinforced polymer made of a plastic matrix reinforced by fine fibers of glass. Fiber glass is a lightweight, strong, and robust material used in different industries due to their excellent properties. Although strength properties are somewhat lower than carbon fiber and it is less stiff, the material is typically far less brittle, and the raw materials are much less expensive. Its bulk strength and weight properties are very favourable when compared to metals, and it can be easily formed using moulding processes. Nowadays, natural fibers such as sisal and jute fiber composite materials are replacing the glass and carbon fibers owing to their easy availability and cost. The use of natural fibers is improved remarkably due to the fact that the field of application is improved day by day especially in automotive industries. Nowadays, nat- ural fiber composites have gained increasing interest due to their eco-friendly properties. A lot of work has been done by researchers based on these natural fibers. Natural fibers such as jute, sisal, silk and coir are inexpensive, abundant and renewable, lightweight, with low density, high toughness, and biodegradable. Natural fibres such as jute have the potential to be used as a replacement for traditional reinforcement materials in composites for applications which require high strength to weight ratio and further weight reduction.

Study On Mechanical Properties And Morphology Of Banana-Glass Fibre Reinforced Polypropylene (PP) Hybrid Composites

Study On Mechanical Properties And Morphology Of Banana-Glass Fibre Reinforced Polypropylene (PP) Hybrid Composites

In recent years, polymeric based composites materials are being used in many application such as automotive, sporting goods, marine, electrical, industrial, construction, household appliances, etc. Polymeric compositess have high strength and stiffness, light weight, and high corrosion resisitance. Natural fibres are available in abundance in nature and can be used to reinforce polymers to obtain light and strong materials. The information on the usage of banana fibre in reinforcing polymers is limited in the literature. In dynamic mechanical analysis, have investigated banana fibre reinforced polyester composites and found that the optimum content of banana fibre is 40%. The analysis of tensile, flextural, and impact properties of these composites revealed that composites with good strength could be successfully developed using banan fibre as the reinforcing agent. The source of banana fibre is the waste banana trunk or stems which are abundant in many places in the world ( Sapuan, 2005).

compositions (50ºC and 52ºC for V f of 8% and 12% respectively). It is suggested that the incorporation of lower fraction of glass fibre may only give notching effect to the composite. They may introduce a microvoid in the composites and instead of reinforcing the matrix, it weakens the composites. There is no change in T g of composite at V f of 8% and only a negligible increase of 2ºC at V f of 12%. On the other hand, the presence of the glass fibre reduces the magnitude of tan δ max values dramatically. Higher reduction for composites with higher fibre loadings is believed due to the strengthening effect by the fibres. Tan δ max of reinforced composites shows a maximum decrease of about 44% compared to the pure matrix (0.0868 to 0.0488). In this instance, the incorporation of fibres acts as barriers to the mobility of polymer chain, leading to lower degree of molecular motion and hence lower damping characteristics [22]. Another possible reason is that there is less matrix by volume to dissipate the vibration energy.

Fibre and hybrid fibre reinforced geopolymer concrete– A Review

Fibre and hybrid fibre reinforced geopolymer concrete– A Review

Majority of the studies were conducted with a combination of metallic fibre with non-metallic fibres. From tables 4-6, it is evident that hybrid combination of metallic and non-metallic fibres have significant effect on the compressive, tensile and flexural strength. Strength parameters are found to increase with respect to increase in percentage volume fraction of steel fibres in both geopolymer and geopolymer fibre concrete. The combination of steel and polypropylene fibre has better performance than combination of steel with glass fibresbecause of the high elastic modulus of steel fibre and the low elastic modulus of polypropylene fibre. Improved tensile strength can be achieved by increasing the percentage of steel fibres. The higher number of fibres bridging the diametric ‘splitting’ crack, the higher would be the spilt tensile strength. The easy availability of PP fibres, combined with the high stiffness of steel fibres, resulted in the enhancement of the split tensile strength (6). Heat cured hybrid fibre reinforced geopolymer concrete had high strength parameters than ambient cured hybrid fibre reinforced geopolymer concrete.

Experimental Studies On Strengthening Of Rcc Continious Beams Using Frp Sheets

Experimental Studies On Strengthening Of Rcc Continious Beams Using Frp Sheets

Strengthening of structures via external bonding of advanced fibre reinforced polymer (FRP) composite is much less dense and therefore lighter than the equivalent volume of steel which provides a more economical and technically superior alternative to the traditional techniques in many situations as it offers high strength, low weight, corrosion resistance, high fatigue resistance, easy and rapid installation and minimal change in structural geometry. The manufacturing process for glass fibers sheets suitable for reinforcement uses large furnaces to gradually melt the silica sand, limestone, kaolin clay, fluorspar, colemanite, dolomite and other minerals to liquid form. Although many in-situ RC beams are continuous in construction, there has been very limited research work in the area of FRP strengthening of continuous beams.
