Thermoset vs Thermoplastic composites

Thermoset and thermoplastic composites are materials made by combining polymers with reinforcing fibers like carbon or glass. Thermoset composites are formed by shaping and then curing them into a solid, durable material that doesn’t melt when heated again—think of epoxy resins used in aerospace. Thermoplastic composites, on the other hand, can be repeatedly melted and reshaped when heated, offering better recyclability and impact resistance. While thermosets are generally more heat-resistant and stiff once cured, thermoplastics are more flexible and easier to mold or modify after production. Both are used to create lightweight, strong components across various industries.
