Introduction to Prepreg
Prepreg, short for pre - impregnated material, is a composite material that consists of fibers (such as carbon fibers, glass fibers, aramid fibers) pre - impregnated with a resin matrix (usually epoxy resin, phenolic resin, etc.). The resin is in a semi - cured state, which allows for easy handling and storage. Prepregs are widely used in various industries due to their excellent mechanical properties, such as high strength - to - weight ratio, good corrosion resistance, and fatigue resistance. They are commonly applied in aerospace, automotive, sports equipment, and marine industries.
