Abstract: A molding compound is made by heat-softening, fusing and compressing strips of unidirectionally aligned filaments embedded in a thermosetting resin. The thermosetting resin is non-tacky at room temperature, which allows for easy handling, elimination of cold storage and the use of robotic manufacturing methods. Composites made by molding the molding compound have excellent, highly isotropic tensile properties.

Abstract: Fiber reinforced composites are made by infusing a mass of reinforcing fibers with a resin composition (11). A thin sheet (6) of nano-sized monofilaments (7) is applied on at least one major surface of a fiber mass. The resin composition (11) is subsequently hardened to form the composite. This method produces a composite having a very smooth surface. Printout of the reinforcing fiber is greatly reduced without the need to mask it through the application of thick coatings or additional layers of material.

Abstract: Multilayer prepregs are formed by stacking layers of unidirectional prepregs in which continuous reinforcing fibers are aligned in a single direction. The unidirectional prepregs are made by impregnating aligned tows of a reinforcing fiber with a solid thermosetting resin that softens at a temperature below its cure temperature. The layers of the stack are bonded together by softening and then re-cooling the resin portion of the individual prepreg layers. The multilayer prepreg is then molded and cured to form a composite part.
