Unidirectional ( UD ) fabric is one in which main, long, structural fibers are oriented in one direction, held in place by secondary non-structural stitching threads. Structural orientation can be in 0 or 90”. Unidirectional fabrics offer the ability to place fibers in the component exactly where required and in the optimum quantity.
