ABSTRACT:
A fiber reinforced thermoplastic structure having multiple layers of individual reinforcing elements in sheet form 12 or as a single continuous strand 12a of continuous monofilaments, multi-filaments or spun yarns is disclosed. The layers extend in parallel planes wherein in each plane the individual elements may be in parallel or in non-parallel relation with an included angle of intersection, a, of 0 to 45 degrees as required by a specific application. The structure is manufactured by simultaneously assembling a segmented mold 20, 50 and selectively placing and fixing the location of individual reinforcing elements 12, 12a to give the resultant article described physical properties. The elements are encapsulated by a plastic resin which solidifies in the approximate shape and size of the segmented mold cavity.
