Carbon fiber reinforced composite (CFRP) is one of important technologies to realize auto light weight, and using recyclable composites and mass production are the ways to break through the bottleneck for their large-scale and low-cost application in automotive industry. Based on the self-developed low-pressure and fast Resin Transfer Molding equipment, this project will focus on basic theory and key technologies for design and manufacture of carbon fiber/recyclable epoxy composite (CFREC) automotive structure. A high-performance, recyclable and fast-curing epoxy resin and its corresponding size agent are synthesized, which will solve the recycling problem for CFRP. Based on the integrated design of material-structure-process- properties, the method of multiple structure design will be established. By the reveal of recyclable epoxy resin flow and curing mechanisms in carbon fibers in RTM, the key technologies for controllable preparation and property control of CFREC automotive structure will be developed. Furthermore, through the assessment of concrete application, testing methods and evaluation system for CFREC automotive part will be established. The research results will provide technical guidance for the design and manufacture of CFRP automotive structure. It will also promote the execution of the "Fusion of Informatization and Industrialization" strategy.
