A composite material’s key components are fibers and a resin. The fibers, typically made of glass or carbon fiber, provide strength and stiffness, but if used alone, cannot be made into a shape or form where these properties are applicable. Impregnating the fibers with resin followed by curing, however, allows us to engineer their strength, stiffness and light weight for a variety of applications, while adding even more benefits to the composite.

FAQ: Resins

What is a resin?

A solid or pseudo-solid organic material, generally of a high molecular weight. In fiber reinforced plastics, it is the resin that binds the fibers.

What are the major groups of resins?

Thermoplastic and Thermoset resins. 

What is a thermoplastic resin?

Polymers or copolymers that essentiall have no cross-links and can be melted or reshaped when heated to melt point or above the Tg.

What is a thermoset resin?

A plastic that cures by the application of heat or by chemical reaction resulting in a cross-linked insoluble molecule; considered an irreversible process.
