Evaluation of Mechanical Properties of Jute and Kevlar Fiber Reinforced Materials

Abstract

The purpose of this paper is to investigate the mechanical properties of kevlar fiber and jute fiber reinforcement. Nowadays the composite materials are widely used materials. Having wide range of applications due to its light weight, high strength and low cost. These composite materials are now being explored in applications of aerospace and automotive industries. In the present work, the composite material is prepared with intermediate aramid fabric layer (Kevlar) which is high strength fiber and it is combined with jute fabric reinforced epoxy composite to increase the strength of kevlar. This composite material is tested for mechanical properties like flexural, tensile & impact strength are calculated with UTM (universal testing machine) for flexural, tensile tests and impact testing is done with impact testing machine. Through this test results the impact strength of the composite material is calculated. The energy dissipation by impact test of jute and kevlar fabric composite and strength of fibers will be analyzed by scanning electron microscopy (FESEM). Thermo gravity analysis (TGA) and differential thermal analysis (DTA) is carried out. Through these test results it can conclude that the jute can be combined with the kevlar where the impact is primary considerations like bulletproof vests, automobile bodies, tyres etc. The usage of jute in all kevlar applications will increase the strength of kevlar by reducing the usage of Kevlar and cost will be minimized.
