What is prepreg?

Prepreg is a composite material that consists of a reinforcing fabric (such as carbon fiber or glass fiber) that has been pre-impregnated with a thermosetting resin matrix (such as epoxy or phenolic). The resin is pre-cured, which means that it is partially cured to a solid form but still has some fluidity. Prepreg is used in many industries, including aerospace, automotive, and sports equipment manufacturing, due to its high strength-to-weight ratio, excellent thermal and chemical resistance, and ease of use.

Prepreg is typically available in roll form, and it can be cut to size and layered in a mold before being cured at elevated temperatures and pressures to create high-performance composite parts. The resin content in prepreg is carefully controlled, allowing for precise control over the mechanical properties of the final product.

Overall, prepreg is a popular choice for manufacturing high-performance composite components due to its excellent mechanical properties, versatility, and ease of use.
