Abstract

The replacement of carbon fiber reinforced epoxy resin matrix composite (CFRP) in the B-pillar of the body structure was discussed. Under the condition of ensuring crashworthiness, the lightweight application of B-pillar on the structural parts of the automobile was realized. Taking the steel B-pillar of a certain model as the prototype, CFRP is used for the same stiffness design, and the stiffness, crashworthiness and lightweight performance of the composite B-pillar relative to the high-strength steel B-pillar are comprehensively analyzed. The results show that under the requirements of crashworthiness, the lightweight effect of CFRP on B-pillar is obvious, which is 26.27% lower than that of high-strength steel B-pillar. Therefore, under the equal stiffness design conditions, the composite material can better realize the lightweight requirements of the automobile B-pillar.
