NOVELTY - Production of a molded article made of fiber-reinforced thermoplastic material, comprises knead melting a composition comprising a thermoplastic material in its solid state and reinforcing fibers, which are sized with a material, which contains a polymer(s) consisting of polyurethane, polyurea, and isocyanate derivatives polyurethane, or isocyanate derivatives of polyurea.    USE - The process is for production of a molded article or molded part made of fiber-reinforced thermoplastic material, i.e. polyolefin or polypropylene. The article is a battery tray (claimed) mountable to a structural component of an associated automotive vehicle.    ADVANTAGE - The process provides molded parts having highly oriented or ordered positioning and distribution of reinforcement fibers length, relative to fluid flow into the associated mold cavity. The polymeric material demonstrates superior strength and durability. The article has at least one cantilever and a tensile strength at break of greater than or equal to20000 pounds/square inch (psi). The molded parts are resistant to degradative materials present, in the automotive device, such as battery acid.    DETAILED DESCRIPTION - Production of a molded article made of fiber-reinforced thermoplastic material, comprises knead melting a composition comprising a thermoplastic material in its solid state and reinforcing fibers, where thermoplastic material of the composition has a melt flow index of greater than or equal to25 g/10 minutes according to ASTM D1238, and where reinforcing fibers of the composition have an average length greater than 0.375 inch, and are sized with a material, which contains a polymer(s) consisting of polyurethane, polyurea, and isocyanate derivatives polyurethane, or isocyanate derivatives of polyurea, where reinforcing fibers are filamentized in a homogenous dispersion throughout the solid polymeric material; transferring the knead melted material into a closed cavity mold device; and upon solidification, removing a finished articles from the mold device.
