Braiding

A textile process in which fibre tows are interlaced by rotating carriers to form tubular or flat preforms, often applied directly over a mandrel or core. Braided preforms offer good torsional properties and damage tolerance and are used for shafts, tubes and structural nodes.

Also known as: Overbraiding

Filament winding

A process in which continuous fibre tows, wetted with resin or pre-impregnated, are wound under tension onto a rotating mandrel in controlled patterns and then cured. It is the standard method for pressure vessels, pipes, tanks and other axisymmetric structures.

Resin transfer moulding

RTM

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.

Roving

A bundle of parallel, untwisted glass fibre strands wound onto a cylindrical package. Direct rovings feed processes such as filament winding, pultrusion and weaving, while assembled (multi end) rovings are designed for chopping in spray up; rovings are specified by tex and by sizing type.
