- 1 - Abstract: The present invention provides non-woven reinforce- ments for resinous composites. The reinforcements are constructed with warps consisting of non-twist yarns or soft twist yarns of multi-filaments having a high strength and a high modulus, on one or both sides of wefts of non- twist yarns or soft twist yarns containing an adhesive agent. The warps and the wefts are bonded together at their intersections. As the reinforcement of the present invention has no flexure, the physical properties of the fibers such as high strength, high modulus and the like, is reflected in the composites using the reinforcement. In the reinforcement, the warp is not substantially restrained, so that a matrix resin can be impregnated sufficiently into the reinforcement. Further, the reinforcement can be easily handled, because its shape is maintained by adhesion, and it does not become loose when cut.
