Prepreg is the abbreviation of Preimpregnated Materials. It is a prepreg sheet product made of matrix impregnated in reinforced fiber and is the intermediate material of composite materials.
The reinforcing materials mainly include carbon fiber, glass fiber, aromatic polyamide fiber, etc.
The matrix materials mainly include epoxy resin, polyester resin, thermoplastic resin, etc.
Compared with other materials, the composite produced by Prepreg can improve strength, hardness, corrosion resistance, fatigue life, wear resistance, impact resistance, weight reduction and other characteristics,
Recently, it is often used in the production of aerospace industry, military industry, medical, new energy, photovoltaic, wind energy, sports, leisure products, etc.
