Composites Resins

Resins play a pivotal role as the matrix material in composite structures, bonding and encapsulating reinforcements like fibers within the composite. These materials, commonly in liquid form before curing, undergo a transformation into a solid, durable substance. Resins vary widely in type, such as epoxy, polyester, vinyl ester, and more, each offering distinct properties like adhesion, flexibility, and temperature resistance. The selection of resin significantly influences the composite's final characteristics, including strength, durability, and chemical resistance.

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.
