Abstract：

To meet lightweight and high-strength demands of new energy vehicles, a new lightweight idea

for the load-carrying parts was put forward by combining high strength steel metal with CFRP

prepregs to form Steel/CFRP laminate materials, which is a matching design that has

complementary advantages. For the above Steel/CFRP laminate materials, a combined hot stamping

process was proposed to implement the efficient mass production of lightweight Steel/CFRP

automotive components. Then, the corresponding process principle and feature described. In

addition, a set of die, whose temperature and heating rate were controllable, was designed to

implement the combined hot stamping of Steel/CFRP boxlike parts. And the mold structure and

its main parts were introduced. Finally, the related process experiments were conducted. The

experimental results show that the feasibility and validity of the proposed process are

verified, and the study provides necessary test samples on formability, deforming behavior,

interface bonding status, security and energy absorption capability, etc. of Steel/CFRP

laminate materials for follow-up investigation.
