3D woven fabric

Separation of the plies within a laminate, caused by impact, manufacturing defects, fatigue or moisture ingress. Because it can spread unseen beneath an undamaged surface and sharply reduces compressive strength, delamination is a primary target of non-destructive inspection.

A tubular or flat reinforcement made by interlacing yarns in a helical pattern, typically as a biaxial or triaxial braid. Braids conform well to curved and tapering geometry and are commonly used to overbraid cores and mandrels for tubes, struts and other slender components.

A closed-mould process in which a dry fibre preform is placed in a matched mould and liquid resin is injected under pressure before curing. It produces parts with two moulded faces, good dimensional control and repeatable quality at medium to high volumes.
