Abstract: The present invention is directed generally to cloth-like fiber reinforced polypropylene compositions, and the beneficial mechanical and aesthetic properties imparted by such compositions. The cloth-like fiber reinforced polypropylene compositions include at least 25 wt % polypropylene based polymer, from 5 to 60 wt % organic reinforcing fiber, from 0 to 60 wt % inorganic filler, and from 0.1 to 2.5 wt % colorant fiber. A method of making fiber reinforced polypropylene compositions and molding articles there from is also disclosed and includes the steps of twin screw extrusion compounding the composition to form a resin and injection molding the resin to form a cloth-like article. Articles molded from these fiber reinforced polypropylene compositions have a flexural modulus of at least 300,000 psi, exhibit ductility during instrumented impact testing, and exhibit a cloth-like appearance. The cloth-like fiber reinforced polypropylene compositions of the present invention are particularly suitable for making molded articles including, but not limited to household appliances, automotive parts, and boat hulls.

Abstract: The present invention is directed generally to processes for making fiber reinforced polypropylene resins including at least 25 wt % polypropylene based polymer, from 5 to 60 wt % organic fiber, and from 0 to 60 wt % inorganic filler. The process includes extrusion compounding the polypropylene based polymer, the organic fiber, and the inorganic filler to form a fiber reinforced polypropylene resin, which is subsequently molded to form an article with a flexural modulus of at least 300,000 psi, that exhibits ductility during instrumented impact testing (15 mph, −29° C., 25 lbs). Twin screw extruder compounding processes where the organic fiber is continuously fed to the extruder hopper by unwinding from one or more spools, and uniformly dispersed in the fiber reinforced polypropylene resin by twin screws having a combination of conveying and kneading elements are also disclosed.
