The Manufacturing Technology Research of Composite Resin Transfer Molding

摘要

The main requirements of preparation of composite materials in aerospace industry are affordable, highly automated and good quality control. To reduce the mold cost and shorten the production cycle, the aviation industry is focusing on weaving technology, advanced spread with technology, autoclave technology, injection process, advanced curing process; all quality concept and thermoplastic process. The main principle of RTM process is laying reinforced material form in the cavity, in accordance with the requirements of performance and structure, injection equipment will be used by special resin system of closed cavity, mold has fastening, injection mould with peripheral seal and exhaust system, which ensures that the resin flow smooth out all the gas in the cavity side by side and infiltrating fiber thoroughly, it also has heating system, which is used as heating composite components of curing forming.
