What is a Prepreg?

Prepreg (Pre-impregnated) refers to fiber materials that are pre-impregnated with resin, primarily used in industries such as aerospace and automotive where lightweight and high strength are required. The fibers are impregnated with resin in advance, simplifying the curing process. Prepregs can use thermosetting resins or thermoplastic resins, and they are cured at high temperature and pressure to form a strong structure. Common fiber types include carbon fiber and fiberglass, which are ideal for applications requiring lightweight and high strength. Prepregs are widely used in the manufacture of aircraft parts, sports equipment, and vehicle components due to their stability in manufacturing processes and high-performance characteristics.

Application of Prepreg

１．Aircraft Parts: Prepreg is used in aerospace applications such as structural components of aircraft, including wing parts and fuselage reinforcements, where lightweight and strength are crucial.
２．Automotive Parts: Prepregs are used in vehicle bodies and chassis for weight reduction and improved strength.
３．Sports Equipment: Prepreg is also utilized in high-performance sports equipment, such as bicycle frames and golf clubs, due to its strength-to-weight ratio.
