MECHANICAL PROPERTIES OF KEVLAR S GLASS AND CARBON FIBER WITH GRAPHITE POWDER

Abstract

Composite materials are composed of two or more component elements mixed together to produce a material 
that is better than the sum of its constituent parts. In composite materials, synthetic fibres like aramid, carbon, and glass 
fibre are often used as the reinforcing element. These fibres tolerate fatigue well, are lightweight, and are robust. The matrix 
material, which encases the fibres, is often composed of thermoplastic or epoxy resin. The toughness and durability of the 
composite are derived from the matrix material.Applications for composite materials are many and include sports goods, 
automotive, aerospace, and marine industries. Composite materials are utilised in the automobile industry to create 
lightweight door panels, spoilers, and bumpers. Additionally, structural parts like the hood and trunk lid are made with 
them.The purpose of this research is to create and evaluate seven distinct composite material combinations for usage in car 
bumpers. Carbon fibre, graphite powder, S glass, and Kevlar will all be used. The hand layup method will be used to 
produce the composites. Each composite will undergo testing for its tensile strength, flexural strength, impact strength, and 
hardness. Which composite is ideal for usage in car bumpers will be determined by looking at the test results.CATIA and 
ANSYS will be used for design and analysis, respectively, on the automobile bumper. For every material, the von-Misses 
stress and overall deformation of the bumper will be computed. The analysis's findings will be utilised to confirm the 
experimental tests' conclusions.This study will provide important knowledge on the use of composite materials in car 
bumpers. The project's outcomes will assist engineers in choosing the ideal composite material for certain applications.
