Abstract This paper introduces the main categories and characteristics of LCM composites, and discusses the progress of LCM resin, tackifier for LCM resin and preparation process of LCM preform in China and abroad. Some new processes of LCM, such as HP-RTM process, thermoplastic resin liquid molding process, automatic laying liquid forming process and SQRTM forming process are introduced. And the future development trends of LCM are prospected.
