Problems solved by technology

However, there are many problems and defects in the autoclave molding technology: (1) The autoclave has a long curing time, high energy consumption and low resource utilization
This heating method is inefficient, takes a long time, and the temperature control has hysteresis, which consumes a lot of energy
(2) Unacceptable temperature gradients and poor compaction will occur in components of large size and thickness formed by autoclave
At the same time, there are some defects in the bonding interface of the composite material co-cured in the autoclave, and the mechanical properties are not ideal, which affects the quality and service life of the composite material

Description

technical field [0001] The invention relates to a method and a device for microwave curing composite materials, and belongs to the technical field of composite material curing molding technology and equipment. Background technique [0002] Composite materials have the advantages of high specific strength and specific stiffness, light weight, heat resistance, corrosion resistance, fatigue resistance, good shock absorption performance, etc., and are widely used in aerospace, transportation, wind power generation, 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 composite materials, different molding methods have been developed for different composite material components. Among them, the autoclave forming method is widely u...
