为了满足新能源车辆对轻量化及高强度的严苛要求,提出将高强度钢板与CFRP预浸料组成Steel/CFRP复层材料,通过两种异质材料的匹配设计和优势互补,实现车体承力件轻量化新思路。针对Steel/CFRP,提出适用于轻量化Steel/CFRP车体构件高效量产的混合热共冲工艺,阐述了其工艺原理及特点;设计开发了用于Steel/CFRP复层材料盒形件混合热共冲成形工艺试验用的可加热温控模具,介绍了其结构组成及主要零件。开展了相应的工艺试验,证明了所提出Steel/CFRP复层材料构件混合热共冲工艺方案的可行性和有效性,为后续对Steel/CFRP构件混合热共冲过程中材料的成形性能、变形行为、界面结合状态及安全性、吸能性研究,提供了必需的实验样品。
In order to meet the stringent requirements of light-weight and high-strength vehicles for new energy vehicles, a steel / CFRP composite material made of high-strength steel and CFRP prepreg is proposed. Through matching design and complementary advantages of two heterogeneous materials, New lightweight lightweight components. Aimed at Steel / CFRP, a hybrid hot co-flushing process suitable for high-volume production of lightweight steel / CFRP bodywork is proposed. The principle and characteristics of the process are described. A total of red forming process test can be used to heat the temperature control mold, introduced its structure and the main components. The corresponding technological tests were carried out to prove the feasibility and effectiveness of the proposed hybrid thermal co-flushing process for Steel / CFRP composite components. For the subsequent formability and deformation of the steel / CFRP composite during hot co- Behavior, interface combination of state and safety, energy absorption studies, provided the necessary experimental samples.
