Stitched

A stitched reinforcement is constructed using a combination of unidirectional reinforcements that are stitched together with a non-structural synthetic such as polyester. Stitched fabrics offer greater strength and stiffness per unit thickness as compared to standard woven rovings. A layer of mat may also be incorporated into the construction. While the stitching does have the effect of crimping the fibres, the crimping is far less that with a woven roving. Additionally, reinforcements can be oriented along any combination of axes.
