Warp (0°) Longitudinal Unidirectional,main bundles of fiberglass roving are stitched in 0-degree,which normally weighs between 150g/m2–1200g/m2, and minority bundles of roving are stitched in 90-degree which weighs between 30g/m2-90g/m2. One layer of chop mat(50g/m2-600g/m2) or veil (fiberglass or polyester: 20g/m2-50g/m2) can be stitched onto this fabric. Fibercore fiberglass warp unidirectional mat is designed to offer high strength on warp direction and improve production efficiency.
