“…Bax and Mussig [4] studied the tensile properties of PLA based flax and rayon composite and they found that For flax maximum tensile strength and modulus were 54.15MPa & 6.31GPa respectively for 30 wt% reinforcement and For viscose rayon maximum tensile strength and modulus were 57.97MPa & 4.85GPa respectively for 30 wt% reinforcement. Ochi et al [18] studied the mechanical properties of kenaf PLA composite. They found that the tensile strength increased linearly up to a fiber content of 50 vol% and get maximum strength of 223MPa at 70 vol%.…”

This paper presents a study of the mechanical properties of Kenaf fibre (KF) reinforced floreon (FLO)/ magnesium hydroxide (MH) bio-composites. The mixing of all materials was done by using a 21 mm lab twin screw extruder followed by hot pressing. The composite sheet was then cut into specimens for testing purposes. The scanning electron microscopy (SEM) was used to study the cross-section of the interface. In this regard, insufficient resin for fibre wetting, hydrolytic degradation on the biopolymer and poor interfacial bonding were attributed to the low strength profile. Yet, further addition of KF increased the tensile strength and flexural to 18.91 MPa and 73.09MPa, respectively. Nevertheless, inserting KF and MH filler were found to have a positive outcome on the flexural modulus by especially 10KF5MH and 10KF10MH for 3.02GPa and 3.17GPa, respectively. Insertion of KF and MH showed the deterioration of impact strength. However, addition of KF increased the impact strength to 16.82 J/m 2 . FLO is a hydrophobic biopolymer, and showed only 0.49% of the total water absorption in 14 days. Meanwhile, for the first 24 hours, the rates of water absorption were very high for all biocomposites. Hence, it is worth mentioning that the high contents of KF in bio-composites were found to have higher saturation period and higher total amount of water absorption while the MH caused shorter saturation period but lower total amount of water absorption. However, incompatibility of the interface bonding had increased the water absorption of KF/FLO/MH composites. 5KF5MH and 10KF5MH recorded water absorption at 10.65% and 13.33%. On the other hand, 10KF10MH was saturated at day 6 with 6.59 % of water absorption. Although 10KF5MH specimen did not have the best performance in mechanical properties, higher flame retardancy shall provide KF reinforced FLO composite with MH filler for more applications in the advanced sector, especially a hazardous environment.

Composite manufacturing is the novel branch of science, which finds its immense applications in various industries such as sporting, automotive, aerospace and marine industries. The superior properties of composites such as stiffness, better mechanical properties, low density and light weight make it a candidate in engineering applications. The need for seeking alternate materials with increased performance in the field of composites revived this research, to prepare fiber reinforced composites by hand layup method using E-glass and coconut fibers with length 5-6 mm. The resin used in the preparation of composites was epoxy and polyester. Fiber reinforced composites were synthesized at 18:82 fiber-resin weight percentages. Samples prepared were tested to evaluate its mechanical and physical properties, such as tensile strength, flexural strength, impact strength, hardness and scanning electron microscope (SEM). Scanning electron microscope analysis revealed the morphological features. E-glass fiber reinforced epoxy composite exhibited better mechanical properties than other composite samples. The cross linking density of monomers of the epoxy resin and addition of the short chopped E-glass fibers enhanced the properties of E-glass epoxy fiber reinforced composite.
