Knitted fabric is bundled and stitched together. It provides great directional strength and wets out fast. It builds up thickness quickly which saves time in multi-layer layups. There is no crimping since the fabric is stitched instead of woven. 0/90 configuration has equal strength in both directions. 1.5 oz mat is stitched to the fabric. It is compatible with epoxy, vinyl ester resin, and polyester resin. Call for bulk order pricing.
