LONG FIBER REINFORCED POLYAMIDE66

Long fiber reinforced thermoplastics (LFRT) are produced by pultrusion technology in which the long fibers are fully impregnated thus delivering optimal reinforcement to the plastic matrix. Unlike conventional short-fiber reinforced materials, the longer fibers present in molded parts mechanically interact with each other to form an internal glass fiber “skeleton” that limits anisotropic shrinkage and greatly reduces warpage. The combination of mechanical properties, impact and creep resistance, and low warpage imparted by these LFRT products make them suitable candidates for metal replacement. Tool housings, luggage racks, fan shrouds, wheel and gears are but a few of the current uses of LFRT. The LFRT technology is not just limited to glass. It may employ glass fibers, stainless steel, carbon, aramid or other reinforcing fibers to deliver the property balance required for a wide range of demanding uses. Conventional plastics forming methods such as injection molding, blow molding, rotocasting and profile extrusion can be used with LFRT products where typical fiber lengths range about 10 mm.
