Physical and Mechanical Properties of Pressed Palm Oil Fruit Fiber Reinforced Epoxy Composite for Building Partition Panels

Physical and Mechanical Properties of Pressed Palm Oil Fruit Fiber Reinforced Epoxy Composite for Building Partition Panels

The density, water absorption, and mechanical properties of the pressed palm oil fruit fiber (PPOFF) epoxy composite were investigated. The fibers were matted randomly and laminated with epoxy resin and hardener using hand-lay-up method. The result of the analysis of the developed composite indicated that mass fraction of the PPOFF used in this study was less than the threshold to effect increase in the tensile properties of the resin. However, the properties increased with increase in the fiber content. Also, the density of the composite decreased while the water absorption increased as the fiber content increases. The XRD result indicated that the fibers has high crystallinity index indicating rich cellulose content but the scanning electron microscope (SEM) micrograph revealed weakly bonded fibers to the matrix due to the poor dispersion and wet-ability between the two phases. The developed composite can be useful in building partition panels.

An Investigation of Mechanical Properties of Honge Shell Fiber Reinforced Epoxy Composites

An Investigation of Mechanical Properties of Honge Shell Fiber Reinforced Epoxy Composites

30 Srinivas et al.[8] reported that it is possible to enhance the properties of composites through fiber surface modification by NaOH chemical treatment. The mechanical properties of chemically treated areca fiber composites show better results compared to natural untreated fibers. Impact energy increased from 3 Joules (untreated) to 5 Joules (treated) and hardness number increased from 23HRB to 28HRB. Anilkumar et al.[9] presented the mechanical properties such as tensile, flexural, and compression strength of eucalyptus fiber reinforced composites. The results showed that higher tensile strength of 70.08 MPa, flexural strength 60 MPa and compression strength 182.05 MPa was observed for fiber loading of 25 wt.%. The micrographs showed that there is poor fiber- matrix adhesion and more fiber pull out in 10wt.% fiber content. Tewari et al.[10] developed bagasse glass fiber composite material with 15%, 20%, 25% and 30% of bagasse fiber and 5% glass fiber. The addition of fiber increased the modulus of elasticity of epoxy. Bagasse glass reinforced fiber improves the impact strength of epoxy material due to more elasticity of fiber in comparison to matrix material. In the present study, honge shell fibers which are waste material while extracting honge seeds for the preparation of biodiesel, was used as reinforcement in polymer matrix.

Effect of post curing temperature on mechanical properties of a flax fiber reinforced epoxy composite

Effect of post curing temperature on mechanical properties of a flax fiber reinforced epoxy composite

An interesting alternative to glass fibers is natural fibers such as flax, hemp, or wood fibers. Indeed, natural fibers are carbon neutral, come from a renewable source and can easily be biodegraded [4]. They also have a lower density leading to specific properties similar to those of glass fibers [5,6]. But natural fibers also present some drawbacks: a large variability of mechanical and physico-chemical properties depending on the period of harvesting, the stem location and the extraction method, their low durability because of their hydrophilicity, their sensitivity to high temperature leading to processing difficulties especially during post-curing of thermoset composites [7–13]. This sensibility to high temperature raises several questions in the industrial field: Can the same processing protocol be used for biocomposites? What happens if high temperatures are applied during process?

Mechanical Properties of Jute Fiber Reinforced Composites with Polyester and Epoxy Resin Matrices

Mechanical Properties of Jute Fiber Reinforced Composites with Polyester and Epoxy Resin Matrices

Focus on the development of natural fibers like jute, coir, sisal, pineapple, ramie, bamboo, banana etc., is to explore its application in low load condition. Composites, the wonder material with light-weight, high strength-to weight ratio and stiffness properties have come a long way in replacing the conventional materials like metals, woods etc. The replacement of steel with composites can save a 60-80 percentage of component weight and 20-50 weight percentages with the aluminium components. The polymer based composite materials use is increasing because of their light weight, good mechanical and tribological responses [1]. However, composites encounter problems such as fiber fracture, matrix cracking and delamination. Of these, fiber fracture and matrix cracking plays an important role in laminates under tensile load [2-5].

Mechanical Properties of Carbon/Glass Fiber Reinforced Epoxy Hybrid Polymer Composites

Mechanical Properties of Carbon/Glass Fiber Reinforced Epoxy Hybrid Polymer Composites

designs (Folkes, 1992). The effectiveness of reinforcement essentially depends on the adhesion between matrix and fiber, so this is a key factor in determining the final properties of the composite material, particularly its mechanical properties (Yosoyima et al., 1984; Yosoyima et al., 1990; and Pukzky et al., 1995). In the present work, an attempt has been made to study the influence of glass fiber and carbon fiber reinforced epoxy polymer matrix on the mechanical properties. The hybrid composites were developed by varying the reinforcements from 15%, 30%, 45% and 60% of glass fiber and carbon fiber in 40% epoxy matrix under vacuum bag process.

EFFECT OF WATER ABSORPTION ON THE MECHANICAL PROPERTIES \OF FLAX FIBER REINFORCED EPOXY COMPOSITES

EFFECT OF WATER ABSORPTION ON THE MECHANICAL PROPERTIES \OF FLAX FIBER REINFORCED EPOXY COMPOSITES

Figure 5 shows that tensile strength of all specimens decreased with increasing water ab- sorption rate. These results are because of wa- ter penetration inside polymers decreasing the connection between fiber and polymer material. Composite materials reinforced with flax fibers had many channels and capillary tube which al- lowed for water molecules to penetrate inside the materials and acting along the interface between epoxy and flax fiber causing swells in the sam- ples. Then the bonds between resin and fibers will break. So the strength of the composite material will decrease. For the 10% flax fiber reinforcing the ultimate tensile stress of wet samples is higher than that for dry samples. This could be due to the fact that high amounts of water causes swelling of the fibres, which could fill the gaps between the fi- bre and the polymer–matrix, and eventually could lead to an increase in the mechanical properties of the composites. Dhakal [6] et al has reported similar results in their research for hemp/polyes- ter composites. The tensile stress drops by 38% in their study. Theoretically, high tensile strength of a natural fibre reinforced composite could be achieved by increasing the amount of the fibre used. Singleton et al. [9] investigated the effect of fibre volume fraction on the mechanical prop- erties of flax mat/recycled HDPE composites by film stacking and compression moulding. It was observed that the tensile strength and modulus in- creased with an increase in fibre volume fraction (0%, 10%, 18%, 20% and 30%).

Mechanical properties of hybrid carbon fiber reinforced polyethylene and 
		epoxy composites

Mechanical properties of hybrid carbon fiber reinforced polyethylene and epoxy composites

2.5 wt.% ratio of ultra-high molecular weight polyethylene powder is considered a good additive percentage to the epoxy in terms of tensile strength in this study. The composite material ductility was found to have a positive relationship with the increase of the additives except at 5 wt.% ratio where it exhibited a stiffer behavior. Further investigations of other polyethylene powder additive percentiles especially between 2 wt.% and 5 wt.% is recommended under the same conditions of manufacturing and testing the materials. On the other hand, the impact strength was found to have an inverse relationship with the increase of the additives. The impact loading exert stresses on the matrix higher than tensile loading due to the fact that it creates shear stress, which lead to delamination. This shows the importance of the matrix homogeneity and the effectiveness of the additives to transfer loads throughout the composite materials.
