Abstract

The invention discloses a method and a device for forming a high-performance composite material structural member through a microwave-pressure tank. The device mainly comprises a cooling system (2), a gas storage tank (6), microwave transmission lines (9), microwave radiation antennas (10), a pressure safety valve (11), a polygonal multi-mode resonant cavity (14), a microwave generation and measurement module (17), a temperature measurement and control module (18), a vacuumizing and control module (19), a pressure measurement and control module (20), a power supply module (21), a material platform (23), a forming mold (24), a temperature sensor (26) and a tank body (28). The equipment is microwave forming equipment for the high-performance composite material structural member; a non-solidified composite material structural member is put into the equipment, and the high-performance composite material structural member can be quickly formed by technologies of vacuum bag vacuumizing, gas pressurization and microwave heating; the quality and the performance of the composite material structural member can be improved.

Description

technical field [0001] The present invention relates to a kind of composite material manufacturing equipment, especially a kind of composite material curing molding equipment, in particular to a microwave-pressure tank molding device and method for high-performance composite material components using microwaves to quickly solidify composite materials. Background technique [0002] Fiber-reinforced resin-based composite materials have the advantages of high specific strength and specific stiffness, light weight, heat resistance, corrosion resistance, fatigue resistance, and good shock absorption performance, and are widely used in aerospace, transportation, wind power, electronic power and other fields . Prepreg is a prepreg sheet product made by impregnating reinforcing fibers (carbon fiber, glass fiber, aramid fiber) in a matrix (epoxy resin, polyester resin, thermoplastic resin, etc.). intermediate material. [0003] Due to the above-mentioned excellent properties of co...
