ABSTRACT:
A method and apparatus for aligning discontinuous fibers (F 101, 212) is described. A feeder apparatus (20, 120, 220, 220A) is used to align the fibers in a horizontal plane for feeding to the aligning apparatus (40, 140, 240, 240A) providing an electrical (E) field to orient the fibers in one preselected direction. A support or conveyor (70, 170, 270) receives the aligned fibers. The method and apparatus provides composite products having improved physical properties because of the alignment. The fibers can be of different lengths and a mixture of different types to make composites with controlled microstructure and properties. The composite materials can be in the form of non-woven, discontinuous fiber reinforced thermoplastic stampable sheets with controlled fiber orientation distribution. The composites are useful for a variety of goods.
