Prepreg is a general term for fabric reinforcement, which has been pre-impregnated with a resin system. Generally choose epoxy resin containing curing agent, and distinguish high temperature curing (including 175 to 195 degrees Celsius) and general curing (including 125 to 135 degrees Celsius) according to different curing temperatures. Carbon fiber prepreg is divided into unidirectional prepreg and woven prepreg. Unidirectional prepreg is the most important material in all structural products. It is manually pre-laid in the mold according to different angles. Woven prepreg is used as appearance and reinforcement material.
