ABSTRACT:
A fiber reinforced thermoplastic resin shaped article is prepared by supplying a preheated fiber reinforced thermoplastic resin sheet between upper and lower molds, positioning the upper and lower molds so that a clearance between the upper and lower molds at the time of the completion of mold clamping is larger than a thickness of the unpreheated fiber reinforced thermoplastic resin sheet, and supplying a molten thermoplastic resin in a recess provided in at least one of the upper and lower molds through a resin passage provided in the mold so that a portion formed from the molten thermoplastic resin in the recess is integrated by fusion with a portion formed from the fiber reinforced thermoplastic resin sheet.
