Abstract

A composite sheet (48) is made of a moldable resin and reinforcement fibers, where the resin is a thermo-plastic resin, thermosetting resin or mixture thereof, and the reinforcement fibers are fibers centrifuged from a rotary process fiberizer, where the composite sheet has at least 5 distinct layers of reinforcement fibers per mm of thickness. The composite sheet has at least 10 distinct layers of reinforcement fibers, and preferably at least 30 distinct layers. At least 85 percent of the reinforcement fibers are monofilaments, and the reinforcement fibers are wool glass fibers.
