In order to solve the quality defects in the manufacturing process of panel composite material parts commonly used in aviation products,this paper studies a variety of technological methods,and optimizes technologies including 0 fiber preparation and filling method,tooling structure,hot diaphragm preform process,curing process of adhesive film and prepreg.Through a series of improvements to the process method,the fluidity of raw material resin was verified,and a se-ries of defects in the manufacturing process of panel,such as delamination,void and debonding,and the surface quality of the parts was improved.Finally,the purpose of improving the manufacturing quality of composite panel,meeting the testing requirements and meeting the assembly and use requirements is achieved.
