Thermoset prepregs are composite materials produced by pre-impregnating thermoset resins with various reinforcement materials (carbon, glass, aramid, etc.). These prepregs form strong structures that offer high temperature and mechanical strength by undergoing an irreversible chemical reaction through the curing process. With its superior mechanical and thermal properties, it is used in many sectors requiring advanced technology and high performance.
Classification of Thermoset Prepregs
Epoxy-based prepregs: Epoxy resin is the most widely used thermoset resin. Epoxy prepregs have high strength, high mechanical strength, high temperature resistance (120-220°C) and resistance to chemicals.
Bismaleimide based prepregs: Higher temperature resistance (250-500°C), resistance to radiation and chemicals.
Bismaleimide based prepregs: Higher temperature resistance (250-500°C), resistance to radiation and chemicals.
Benzoxazine based prepregs:
High temperature performance (150-300°C), low moisture uptake, high non-flammability, low smoke and toxicity, low thermal expansion coefficient.
Phenolic based prepregs:
High temperature resistance, high non-flammability, low smoke and toxicity, and resistance to chemicals.
Cyanate ester based prepregs: High temperature resistance (200-450°C), low dielectric constant and loss factor, low moisture absorption capacity, high hardness and strength properties.
Vinyl ester based prepregs: Low water absorption capacity, good mechanical strength, lower temperature resistance (100-140°C) than epoxy resins, good fatigue resistance properties. has.
