Microwave curing method of double vacuum bags for carbon fiber composite parts

Abstract

The invention discloses a double-vacuum bag microwave coagulation method for a carbon fiber composite material part. The method is characterized in that the carbon fiber composite material part is sealed and pressurized by adopting double vacuum bags, and the carbon fiber discharge breakdown problem existing during single vacuum bag microwave coagulation of the carbon fiber composite material part is solved. The carbon fiber composite material is packaged by adopting the double vacuum bags, so that the vacuum degree of the part can be improved, the carbon fiber discharge breakdown can be effectively inhibited, and the compaction degree of the material can be improved to a certain degree. In addition, a high-temperature-resistant flexible material layer is added between the two vacuum bag layers, so that carbon fiber discharge burn-through of the vacuum bags can be effectively inhibited, and the carbon fiber composite material part is always positioned in a constant vacuum environment. Therefore, the carbon fiber discharge breakdown problem in the microwave coagulation process of the carbon fiber composite material part is solved.
