Abstract: A multi-layered, variable-angled, non-crimped fabric for reinforcement of composite structures provides for holding the non-woven yarns as laid-out by adhesion of polymeric adhesive applied to the non-woven yarns. The adhesive layer on the yarns, dissolves as liquid resin is applied to form a composite structure, the polymeric coating dissolving in the liquid resin. The polymeric adhesive dissolves to allow liquid resin to wet-out the yarns. Curing creates the desired composite structure. Filament yarns useful in the present invention include but are not limited to those made of aramid, boron, carbon, fiberglass, nylon, PBO, PEN, polyester, and polyethylene. A preferred adhesive is low molecular weight polyester and a preferred liquid resin is polyester resin.

Abstract: A non-woven, unidirectional, multi-axial layered fabric for reinforcement of composite structures provides for holding the non-woven yarns as laid-out by adhesion of polymeric adhesive applied to the non-woven yarns. The adhesive layer on the yarns, dissolves as liquid resin is applied to form a composite structure, the polymeric coating dissolving in the liquid resin. The polymeric adhesive dissolves to allow liquid resin to wet the yarns. Curing creates the desired composite structure. Filament yarns useful in the present invention include but are not limited to those made of aramid, boron, carbon, fiberglass, nylon, PBO, PEN, polyester, and polyethylene. A preferred adhesive is low molecular weight polyester and a preferred liquid resin is polyester resin. A web of netting material is applied in a similar manner for added physical stability of the inventive reinforcement fabric.
