Abstract: Liquid composite molding (LCM) is one of the main molding processes for fiber reinforced resin matrix composites. With the development of the aerospace industry, high-end equipment has put forward more requirements on the performance and complexity of composite components, and it is necessary to innovate the current LCM molding process. Therefore, the new composite material molding process has become a research hotspot. According to the process categories, this paper summarizes the principle, process characteristics and industrial applications of LCM, automated fiber placement LCM, three-dimensional textile preform LCM and co-curing LCM. Finally, the future development direction of LCM process is suggested.

Key words: liquid composite molding, automated fiber placement, co-curing
