Abstract

The invention provides a stamping and injection integrated molding method for a thermoplastic resin matrix woven composite material. The method includes the following steps of woven fabric cutting, die preparing, layer designing, stamping and die assembling, resin injecting, pressure maintaining and curing, die releasing and part taking and post-treating and inspecting. The stamping and injection integrated molding method for the thermoplastic resin matrix woven composite material integrates the stamping molding technology and the injection molding technology; reasonable layer designing can be conducted on the woven fabric according to stress features of molded parts; the flexible molding performance of the woven fabric is good; and parts with complex surfaces can be molded. Injection molding is conducted under certain pressure and temperature, and it is ensured that thermoplastic resin is fully soaked in a seam of a woven material.

Description

technical field [0001] The invention relates to a molding method of a braided composite material, in particular to a stamping-injection integrated molding method of a thermoplastic resin-based braided composite material. Background technique [0002] With the increasingly prominent energy crisis and environmental crisis, automobile lightweight has become an inevitable choice for the development of the automobile industry. Fiber-reinforced composite materials have the advantages of high specific strength and specific modulus, high temperature resistance, good fatigue resistance, and strong designability, and have been widely used in the aerospace field. At present, the backward molding process and immature structural design technology have become the bottleneck for the large-scale application of advanced fiber reinforced composite materials in the automotive industry. [0003] In the prior art, conventional fiber reinforced composite molding methods mainly include hand lay-u...
