Satin weave

The simplest weave style, in which each warp yarn passes alternately over and under each weft yarn. It is stable and easy to handle but has the highest crimp of the common weave styles, which slightly reduces mechanical performance and limits drape over complex curvature.

A weave style in which warp yarns pass over and under two or more weft yarns in a staggered pattern, producing a characteristic diagonal rib. It drapes and conforms to curvature better than plain weave and has lower crimp, and the 2x2 twill is the most recognisable carbon fibre fabric style.

The two yarn directions in a woven fabric, with warp yarns running along the roll length and weft yarns running across it. Their balance governs the directional properties of the fabric, and the terms ends and picks describe the respective yarn counts.

Reinforcement fibre pre-impregnated with a controlled quantity of resin, usually a partially cured (B-staged) thermoset, supplied in rolls and stored chilled or frozen until layup. Prepregs give precise fibre and resin content and are the standard material form for high-performance aerospace and motorsport laminates.
