Carbon fiber prepregs are primarily classified into “unidirectional carbon fiber prepregs,” “woven carbon fiber prepregs,” and various types of blended prepregs. They are composite substrate materials made from carbon fiber as the reinforcing material, which has been pre-impregnated with resin. Characterized by high strength, light weight, and corrosion resistance, they are widely used in aerospace, automotive manufacturing, sports equipment, and other fields. Through hot-press curing and molding, they enable the efficient production of complex structural components and serve as a key raw material in the manufacture of high-performance composites.
Aramid fiber prepreg is a composite material intermediate produced by impregnating aramid fiber fabric with thermosetting resins (such as epoxy or polyurethane) and subjecting it to a semi-curing process. Combining the high strength, high modulus, impact resistance, high-temperature resistance, and excellent energy absorption properties of aramid fibers with the resin matrix, it forms a lightweight, fatigue-resistant structural material.
Flax fiber prepreg is an eco-friendly composite material intermediate made by using natural flax fibers (such as linen or jute) as the reinforcing phase and impregnating them with resin (such as bio-based or synthetic resin). Flax fibers are lightweight, renewable, biodegradable, and cost-effective, while also offering good tensile strength and energy absorption properties. The resin matrix provides interfacial bonding and molding capabilities, making it suitable for applications with high environmental standards, such as automotive interiors, eco-friendly packaging, and construction formwork.
Glass fiber is an inorganic, non-metallic material with excellent properties that can be used in various composite forming processes, such as filament winding and pultrusion. Due to its uniform tensile strength, roving fabrics can also be woven; in certain applications, the roving is further chopped into short fibers. Glass fiber composites are characterized by corrosion resistance, light weight, and excellent reinforcing properties, and are widely used in aircraft structural components, wind turbine blades, yachts, vehicle bodies, decks, consumer electronics, and other fields.
