Abstract
A production method for a fiber-reinforced thermoplastic resin composite material, the method using a crosshead die () that has a maximum aperture height of 1 mm or more, wherein reinforcing fibers are supplied in a reinforcing fiber bundle to the crosshead die (), the reinforcing fibers are conjugated with a melted thermoplastic resin, and the conjugate is brought into contact with a pressurization surface that is at or below the solidification temperature of the thermoplastic resin, is pressurized, and is shaped to have a thickness that is 50% or less of the aperture height.
