Fibers are interlocked in an alternating pattern over and under each other. Plain weave fabrics have good stability and are ideally suited for flat panels and minimal contour radius.

Satin weaves are typically available in four, five, or eight harness satin. The satin weaves do not intersect at every tow. Instead the tows will float over several intersections and interlock under one. Satin weaves are easily draped to conform to difficult parts.

Twills are available in 2×2, 3×3, and 4×4 twill weaves. The “twill line,” or diagonal rib, characterizes the weave. Each tow warp end floats over two or more picks. Twills are very pliable and have excellent drape while maintaining stability.

A variation of the plain weaves, the multiple warp ends fill tows of yarn and are woven together while being alternately interlocked over and under each other to make heavy fabrics.
