ABSTRACT:
The production process of the present invention can significantly suppress the fuzzing on the surface of the composite material and substantially prevents the accumulation of fractured fibers in the nozzle causative of the breaking of a strand and so on, so that it becomes possible to enhance the take-up speed of the strand and so on, and can provide a long-fiber-reinforced composite material excellent in the dispersion of the fibers in the composite material and the impregnation of a resin. The process comprises impregnating a continuous reinforcing fiber with a molten thermoplastic resin while pulling the fiber, and is characterized in that, after the fiber is impregnated or coated with a molten resin, the resultant fiber is continuously pultruded while squeezing excess resin and the pultruded fiber is passed through a shaping nozzle to regulate the shape to a desired one.
