The resin systems currently developed by the company for thermosetting prepreg mainly include low-temperature cured epoxy resin, medium temperature cured epoxy resin, high-temperature cured epoxy resin, bismaleimide, polyimide, cyanate ester, etc. These resin systems can be combined with different reinforcement materials to prepare different prepreg products, meeting the demand for prepreg in composite materials in various fields such as aerospace and rail transportation. At the same time, the development of high-performance thermoplastic prepreg is also underway.
