1. A pultrusion process for-preparing a low percent of continuous reinforcing fibers composite material comprising the steps of:

  • (a) providing continuous reinforcing fibers wrapped with strands of matrix material having a lower melting point than a melting point of the continuous reinforcing fibers;

    (b) directing the wrapped continuous reinforcing fibers through a heated curing die to melt the matrix material about the reinforcing fibers so as to produce a solid fiber reinforced composite; and

    (c) withdrawing the solid fiber reinforced composite from the curing die wherein the percentage of continuous fibers in the solid fiber reinforced composite is between about 10 percent by volume and about 45 percent by volume.
