摘要： Provided is a fiber reinforced thermoplastic resin molding material including: a thermoplastic resin [A]; a resin impregnated reinforcing fiber filament [E] obtained by impregnating reinforcing fibers [B] with a resin [D] having melt viscosity at 200°C lower than melt viscosity of the thermoplastic resin [A]; and a reinforcing fiber modifier [C] that has melt viscosity at 200°C lower than the melt viscosity of the thermoplastic resin [A] and a difference in solubility parameter value from the thermoplastic resin [A] equal to or larger than 1.0, the molding material including 50 to 98.9 parts by weight of the thermoplastic resin [A]; 1 to 40 parts by weight of the reinforcing fiber [B]; 0.1 to 10 parts by weight of the reinforcing fiber modifier [C]; and 0.2 to 12 parts by weight of the resin [D] relative to total 100 parts by weight of the thermoplastic resin [A], the reinforcing fiber [B], and the reinforcing fiber modifier [C], wherein the resin impregnated reinforcing fiber filament [E] is coated with a resin composition including the thermoplastic resin [A] and the reinforcing fiber modifier [C]. Also provided is a thermoplastic resin molded article having excellent impact strength, whereby fiber break of reinforcing fibers is suppressed when impact is applied to the molded article.
