Abstract:
1. A pultrusion process for-preparing a low percent of continuous reinforcing fibers composite material comprising the steps of: continuously pulling reinforcing fibers through an impregnation chamber comprising a mixture containing precursors and initiators that polymerize when heated above a reaction temperature to produce impregnated continuous reinforcing fibers, wherein the temperature of the impregnation chamber is below the polymerization temperature of the precursors and initiators in the impregnation chamber; wrapping the continuous reinforcing fibers with strands of curable matrix material having a lower melting point than a melting point of the continuous reinforcing fibers, the continuous reinforcing fibers being selected from the group consisting of metallic wire, carbon fibers, polyolefin fibers, polyester fibers, and aromatic polyamide fibers; directing the wrapped continuous reinforcing fibers through a heated curing die to melt the matrix material about the wrapped continuous reinforcing fibers and cure the matrix material so as to produce a solid fiber reinforced composite; and 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.
