Abstract
A fiber reinforced polypropylene composite interior trim cover panel. The interior trim cover panel is molded from a composition comprising at least 30 wt % polypropylene based resin, from 10 to 60 wt % organic fiber, from 0 to 40 wt % inorganic filler, and optionally from 0 to 0.1 wt % lubricant, based on the total weight of the composition, the interior trim cover panel having an outer surface and an underside surface. A process for producing an interior trim cover panel for a vehicle is also provided. The process includes the step of injection molding a composition to form the interior trim cover panel for a vehicle, the interior trim cover panel having at least an outer surface and an underside surface, wherein the composition comprises at least 30 wt % polypropylene, from 10 to 60 wt % organic fiber, from 0 to 40 wt % inorganic filler, and optionally from 0 to 0.1 wt % lubricant, based on the total weight of the composition.
