Abstract
A method for making a fiber-reinforced thermoplastic polymer composition and forming a fabricated article therefrom. A thermoplastic polymer, a masterbatch comprising an elastomer and a reinforcing fiber material are compounded, extruded and immediately formed into a fabricated article. The fabricated article is formed by compression molding, vacuum forming, thermoforming, injection molding, blow molding, profile extrusion or combinations thereof.
Claims17
A method of making a fiber-reinforced thermoplastic polymer composition and forming a fabricated article therefrom comprising the steps of:
- (1) introducing into an extruder a thermoplastic polymer,
- (2) introducing into the extruder a masterbatch comprising an elastomer,
- (3) plasticating the thermoplastic polymer and the masterbatch in the extruder forming a molten thermoplastic polymer composition,
- (4) introducing a reinforcing fiber material into the molten thermoplastic polymer composition,
- (5) extruding a molten, fiber-reinforced thermoplastic polymer composition and (6) forming a fabricated article comprising the fiber-reinforced thermoplastic polymer composition.
