A Lightweight Design of Carbon Fiber Reinforced Plastic Auto Bumper

Abstract

Abstract:

An auto bumper used integral carbon fiber reinforced plastic is designed for a type of electric vehicle based on the lightweigh design requirement and manufacturability. The lightweight solution which meets the crashworthiness requirements is obtained through optimization procedure with Latin hypercube sampling, Kriging metamodel and genetic algorithm. The weight of bumper system is reduced by 36.4%.

Key words: carbon fiber reinforced plastic (CFRP) composite, auto bumper, crashworthiness, Kriging metamodel, lightweight
