    • The present invention is directed to an in-line compounding and molding process for making fiber reinforced polypropylene composite parts and articles that exhibit beneficial mechanical and aesthetic properties imparted by such process and compositions. The in-line compounding and molding process includes the steps of providing an in-line compounding and molding machine comprising a twin screw extruder fluidly coupled to an injection molder; extrusion compounding in the twin screw extruder a composition comprising at least 30 wt% polypropylene, from 10 to 60 wt% organic fiber, from 0 to 40 wt% inorganic filler, and from 0 to 0.1 wt% lubricant to form a melt extrudate; conveying the melt extrudate to the injection molder; and molding the melt extrudate in the injection molder to form a part or article. Fiber reinforced polypropylene articles formed from the in-line compounding and molding process have flexural modulus of at least 300,000 psi and exhibit ductility during instrumented impact testing. Fiber reinforced polypropylene articles formed from the process of the present invention are particularly suitable for making household appliances, automotive parts, and boat hulls.

    • Processes for making fiber reinforced polystyrene compositions from organic fibers, inorganic filler and atactic polystyrene based polymer. The process includes extruding the polymer, the fiber and the filler to form a fiber reinforced polystyrene resin, which is molded to form a ductile article with a high flexural modulus. Organic fiber is unwound from spools, fed to the hopper, and dispersed vi twin screws with conveying and kneading elements. The extrusion compounding and molding processes may be fluidly coupled to provide an in-line compounding and molding process for producing the fiber reinforced polystyrene composites. Colored fiber may also be incorporated into the process to yield articles with a cloth-like appearance. The processes for making fiber reinforced polystyrene compositions are suitable for making molded articles including household appliances, automotive parts and boat hulls.
