Abstract

The invention provides a composite material microwave high-pressure curing device and aims to solve the problems that a hot pressing tank curing technique is large in temperature gradient in a thickness direction of a composite material, poor in interlayer shearing strength, long in curing time, high in energy consumption, and the like. Microwave heating curing molding on a composite material which is vacuumed and tightly compacted with high-pressure gases is implemented with electromagnetic waves, and technical support is provided for high-quality, short-cycle and low-energy consumption curing molding of advanced composite materials.

Description

technical field [0001] The invention relates to a composite material curing device, in particular to a composite material high-pressure curing device, in particular to a composite material microwave high-pressure curing device assisted by high-pressure gas and having an intelligent monitoring function. Background technique [0002] Fiber-reinforced resin-based composite materials are the core materials widely used in various fields with high lightweight requirements, such as aerospace, ships, automobiles, wind power and other fields. Especially in the manufacture of advanced aerospace vehicles, the use of composite materials has been developed from secondary load-bearing components such as aircraft radomes and stabilizers to include wing spars, wing panels, central wing boxes, long stringers, and fuselage barrel sections. and other main load-bearing components. Aerospace composite components have the characteristics of large size and large thickness. For example, the overal...
