“…The Impact and Flexural tests showed superior results for coir fibre epoxy composite. Junior et al [15] examined the ultimate tensile strength property of post-cured polyester composite with very thin coir fibres. It was observed that there is an increase in elastic modulus at 40% of fibre content.…”

Coir fibre, derived from the husk of coconuts, is a natural resource and they are biodegradable and renewable. By incorporating them, any product can become more lightweight and durable, meeting the global desire for eco-friendly and efficient designs. This study has the potential to significantly alter the design of components such as switches and enclosures and it has an international research impact on engineering applications. Coir fibres and Hexagonal-Boron Nitride (h-BN) possess superior mechanical, thermal and physical qualities when reinforced with polymers. Hence novel study is carried out to examinecoir fibre/ h-BN reinforcement in epoxy polymer composites.. Response Surface Methodology via Box-Behnken Design (BBD) is utilized to investigate the mechanical properties such as Tensile Strength, Impact Strength and Young’s Modulus of coir fibre/ h-BN reinforced epoxy polymer composite. The effect of input parameters onresponse is evaluated through regression equation and analysis of variance by using statistical Minitab software. The response optimization represents the maximum Young’s modulus (1597 MPa) by combining coir fibre (5 wt.%), Coir fibre powder size (75 µm) and h-BN (1 wt.%). The response optimization portrays the maximum Ultimate Tensile strength(36.83 MPa) by combining coir fibre (1 wt.%), coir fibre powder size (220 µm) and h-BN (3.78 wt.%). The response optimization reveals the maximum Impact strength (98.35 J/m2) by combining coir fibre (5 wt.%), coir fibre powder size (225 µm) and h-BN(1 wt.%). This work emphasises the use of composite materials that are environmental friendly in a variety of industries such as automotive, electrical, etc.

This paper studied the effects of fiber length and fiber content on the physical, mechanical and water absorption behavior of coir fiber-reinforced epoxy composites. Twenty different samples were prepared by varying the fiber length (3 mm, 6 mm, 9 mm, 12 mm and 15 mm) and fiber content (5 wt%, 10 wt%, 15 wt% and 20 wt%) using the hand lay-up technique. The density, hardness, tensile strength, tensile modulus, flexural strength, impact energy, compressive strength, compressive modulus, inter-laminar shear strength, fracture toughness and percentage of water absorption of the composites were analyzed. The experimental investigation reveals that the void content and percent of water absorption increases with increase in fiber length and fiber content. The result shows that the density of composites increases with increase in fiber content, while a decrease in density is observed with increase in fiber length. Similarly, the tensile strength, compressive strength, inter-laminar shear strength, flexural strength, and impact strength show their maximum values at 12 mm fiber length and 15 wt% of fiber content. The hardness and tensile modulus, on the other hand, increase with increase in fiber length and fiber content. Morphological analysis is also carried out to observe the fiber pull-out and fracture behavior of the composites using scanning electron microscope.
