摘要/Abstract

摘要：

复合材料是实现汽车轻量化最具潜力的材料之一。热固性树脂具有优异的力学性能和化学稳定性，但其再成型和回收是一个难题。本文研究汽车B柱热固性树脂基复合材料加强板的制造与回收方法，基本思路是在热固性树脂中引入动态共价键，通过碳纤维预浸料的逐层铺设和热压成型，实现热固性树脂基复合材料加强板的制造和回收。与钢制加强板相比，制备的热固性复合材料加强板轻量超过50%，复合B柱的冲击力峰值降低超过30%，实现了热固性复合材料加强板中碳纤维的无损全回收，回收树脂的单轴拉伸强度保持率超过95%。本文研究为轻质可回收热固性树脂基复合材料汽车构件制造提供了新思路，可推广到其它相关领域。

Abstract:

Composite is the most promising material for achieving structural lightweight. Thermosetting composites have excellent mechanical properties and chemical stability， but their remanufacturing and recycling are extremely challenging. In this work the manufacturing and recycling methods for the thermoset composite support plate of car B-pillar are studied. The basic idea is to introduce dynamic covalent bonds into thermosetting composites， and achieve manufacturing and recycling of thermosetting resin based composite reinforcement plates through layer by layer laying and hot pressing of carbon fiber prepreg. Compared with steel reinforced plates， the prepared thermoset composite reinforced plates reduce weight by more than 50%， and the peak impact force of composite B-columns is reduced by more than 30%. The non-destructive full recovery of carbon fibers in thermosetting composite reinforcement plates has been achieved， and the uniaxial tensile strength retention rate of the recovered resin exceeds 95%. This study provides a new approach for manufacturing lightweight and recyclable thermosetting resin based composite automotive components， which can be extended to other related fields.

Key words: thermosetting resin based composites, automotive B-pillar, reinforcement plates, dynamic covalent bonds
