ABSTRACT:
A body containing lengths of fiber embedded therein is formed by providing a winding fixture including a plurality of parallel support rods spaced apart in a Z-direction. A length of a fiber is wound over the rods such that a portion of the fiber extends in the Z-direction, to form a skeletal structure. The fiber may be coated, as with a resistive material to modify energy absorbtion, after winding. The skeletal structure is filled with foam, and the support structure is removed to leave a structure in which discrete lengths of fiber embedded in the foam lie parallel to the Z-direction. The fibers may be transferred to a sheet of uncured polymeric material by placing the foam piece in contact with the sheet of polymeric material and forcing the fibers into the sheet under an applied pressure.
