Filament winding

A continuous process in which fibre reinforcement is drawn through a resin bath and a heated die, curing into a constant cross-section profile such as a rod, tube or structural section. It gives very high fibre alignment along the pull direction and suits long production runs.

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.

A robotic process that lays narrow tows of prepreg or dry fibre onto a tool surface under controlled heat, pressure and tension, steering each tow individually. It enables complex curvature and tailored fibre paths on large structures with high deposition accuracy and low material waste.

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.
