The processing of fiber reinforced laminates can be divided into two main steps:

Lay–up Curing Curing is the drying and hardening (or

polymerization) of the resin matrix of a finished composite. This may be done unaided or by applying heat and/or pressure.

Lay–up basically is the process of arranging fiber–reinforced layers (laminae) in a laminate and shaping the laminate to make the part desired.

Winding Operation

Molding Operation

The most important operation in this category is filament winding. Fibers are passed through liquid resin, and then wound onto a mandrel. After lay–up is completed, the composite is cured on the mandrel. The mandrel is then removed by melting, dissolving, breaking–out or some other method.

Molding operations are used in making a large number of common composite products.
