摘要： Disclosed is fiber-reinforced thermoplastic resin pellets that satisfy the quality stability (homogeneous impregnation, deterioration prevention of reinforcing fiber) of the molding material and the strength performance of the molded product, using natural discontinuous fiber as the reinforcing fiber, and a manufacturing method of the pellets. A plurality of spun yarns with No. 5 to 80 counts are twisted 10 to 200 turns/m and pultruded when fiber-reinforced thermoplastic pellets containing natural fiber as the reinforcing fiber are manufactured by the impregnating pultrusion method.
