Abstract

Abstract:

Injection overmolding after compression for thermoplastic composites balances the low cost and high performance. It can quickly and stably achieve integration of continuous/discontinuous fiber-reinforced composites， meeting the requirements of the automotive industry. This paper reviews the key points of equipment selection， process control and molding simulation， introduces the types of domestic materials， summarizes the optimization design methods for anisotropic bi-material structures， generalizes the evaluation methods for interface and overall performance， and puts forward some critical scientific and technological issues in the integrated design of "material - process - structure - performance".

Key words: automotive lightweighting, thermoplastic composites, injection overmolding after compression process, integrated design and manufacturing, bi-material interface
