Impact Analysis of Frontal Car Bumper using Long Fibre Reinforced Thermoplastics

Abstract

The front and rear of the vehicle should be protected in such a manner that low speed collisions will only damage the vehicle slightly, or not at all. In automotive components the use of natural fibers has increased to reduce the weight and increase the strength and safety of the automobile components. Natural Fiber Thermoplastic components in automotive industry can afford the advantages of weight, cost reduction and recyclability, compared to conventional materials. The purpose of this project is to design a bumper which is to improve crashworthiness of the bumper beam. These materials had been studied by impact modeling using Finite Element Analysis software, LS DYNA to determine the energy absorption by analyzing the kinetic energy, displacement and impact force. The selected materials are compared to each other for the design parameters like shape, material and impact condition to validate the crashworthiness.
