摘要：
The present invention relates to a process for preparing molded articles of fiber-reinforced thermoplastic resin (FRTP) by conducting laminated molding of:(a) prepregs comprising woven reinforcing fibers impregnated with thermoplastic resin and containing at least one notch, and(b) sheet prepreg comprising unidirectionally arranged reinforcing fibers impregnated with thermoplastic resin and containing at least one notch in a direction traversing the unidirectionally arranged fibers. The molded articles of FRTP obtained by the process of this invention are high quality products free from warpage, torsion and uneven strength.
