  • Publication number: 20170001385
    Abstract: A method for preparing a high quality thermoplastic prepreg, includes: laminating a thermoplastic resin film having a crystallization degree in a range of 1 to 20% on at least one surface of a matrix fiber; and heating the laminate to a higher temperature than a melting point of the film, then, pressing the same. The method uniformly impregnates a matrix fiber with a thermoplastic resin, has a short curing cycle in the formation, and involves no random modification in alignment of fibers in the matrix fiber due to a low crystallization degree of the impregnated thermoplastic resin, thereby increasing rigidity of a formed product and enabling reduction of thickness. Thus produced prepreg has a low weight variation per unit area.
