Abstract

Abstract:

In view of the excellent mechanical properties （light weight and high strength） of carbon fiber reinforced polymer （CFRP）， the original steel bumper beam of a passenger car is replaced by CFRP one， with its stacking sequence optimized in this paper. Firstly， the material parameters are obtained through the mechanical property tests of CFRP laminates， with its accuracy verified by three point bending simulation test. Then the thickness of CFRP bumper beam is determined based on equivalent stiffness design principle， and a low?speed collision finite element simulation is performed to compare the crashworthiness of steel and CFRP bumper beams. On this basis， with the mass， specific energy absorption， maximum intrusion and peak collision force of bumper beam as objectives， a stacking sequence optimization is conducted on CFRP bumper beam to determine the optimum stacking scheme by adopting entropy?based TOPSIS approach. The results show that the mass of CFRP bumper beam optimized is 76.82% less than original steel one， while ensuring the requirements of crashworthiness.

Key words: bumper beam, CFRP, crashworthiness, entropy?based TOPSIS approach, lightweighting
