Industry knowledge of carbon fibre, prepreg and sheet cutting machine：

The prepreg is a composition of a resin matrix and a reinforcement by impregnating a continuous fiber or fabric under a strictly controlled condition with a resin matrix, and is an intermediate material for manufacturing a composite material.

According to the physical state classification, the prepreg is divided into a unidirectional prepreg, a unidirectional fabric prepreg, and a fabric prepreg; according to the resin matrix, the prepreg is divided into a thermosetting resin prepreg and a thermoplastic resin prepreg; Different materials, divided into carbon fiber (fabric) prepreg, glass fiber (fabric) prepreg, aramid (fabric) prepreg; according to the length of the fiber, divided into short fiber (4176mm or less) prepreg, long fiber (1217mm Prepreg and continuous fiber prepreg; according to different curing temperatures, it is divided into medium temperature curing (120 ° C) prepreg, high temperature curing (180 ° C) prepreg and prepreg with curing temperature exceeding 200 ° C.
