Prepreg - Weihai Lanke Composite Material

2021-08-04


Prepreg is a composition of resin matrix and reinforcement made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions, serving as an intermediate material for manufacturing composite materials.

Classified by physical state, prepregs are divided into unidirectional prepregs, unidirectional fabric prepregs, and fabric prepregs; based on different resin matrices, they are categorized into thermosetting resin prepregs and thermoplastic resin prepregs; according to different reinforcement materials, they are classified into carbon fiber (fabric) prepregs, glass fiber (fabric) prepregs, and aramid (fabric) prepregs; based on fiber length, they are divided into short fiber (below 4176mm) prepregs, long fiber (1217mm) prepregs, and continuous fiber prepregs; according to different curing temperatures, they are categorized into medium temperature curing (120℃) prepregs, high temperature curing (180℃) prepregs, and prepregs with curing temperatures exceeding 200℃.
