Abstract
A fiber-reinforced thermoplastic resin composite material comprises a thermoplastic resin, 5 to 80% by weight of a fiber reinforcing material having an average diameter ranging from 3 to 21 .mu.m and an average length ranging from 0.3 to 30 mm, and 0.01 to 5% by weight of carbon black whose aggregate size upon primary cohesion is not more than 60 nm. The composite material permits effective prevention of any snapping of glass fibers for reinforcement in molded articles which are colored black or gray due to the contribution of the carbon black having a specific aggregate size incorporated into the resin along with the fiber reinforcing material. Therefore, the composite material can provide molded articles excellent in mechanical strength, for instance, all of tensile strength, flexural strength and Izod impact strength.
