    摘要： A composite molded article which is produced by joining multilayer boards composed of fiber-reinforced thermoplastic resin onto the surface of a core material made of a foamed resin, and its production method. The composite molded article is constituted by a core material which is composed of a foamed resin molded into a desired shape, and the multilayer boards which are produced such that a plurality of prepregs containing reinforcement fiber by a volume content of not less than 30% and not more than 85% are laminated with the direction of the reinforcement fiber being different with respect to each other, and are heated to not less than a melting temperature of a thermoplastic resin contained therein so as to mutually glue the prepregs, and to remove air contained inside. When the composite molded article is produced, the multilayer boards having been molded into shapes adapted to a shape of the core material are heated to not less than the melting temperature of the thermoplastic resin and are pressed and glued to the core material to make the composite material article.

    摘要： Method and apparatus for manufacturing a sheet-prepreg reinforced with fibers wherein a sheet of fibers such as warp or woven fibers such as fabrics is conveyed between a pair of band belts one of which is coated with a film of thermoplastic resin which has been heated higher than its softening point to enhance resin-impregnating efficiency and prevent the impregnated resin from contacting air. Further, when the sheet of fibers or woven fibers is conveyed in this manner, the molten resin is not maintained on the manufacturing line, thereby preventing it from being deteriorated by heat. The apparatus can be thus kept under operation for a long time and the sheet-prepreg reinforced with the fibers can be made much higher in quality and the deterioration of the impregnated resin can be further delayed.

    摘要翻译： 制造用纤维增强的片材预浸料的方法和装置，其中将诸如织物之类的经纱或织造纤维的纤维片材在一对带带之间输送，其中一条带带被涂覆有已经被加热的热塑性树脂膜 比其软化点提高树脂浸渍效率并防止浸渍树脂与空气接触。 此外，当以这种方式输送纤维或织造纤维时，熔融树脂不会保持在生产线上，从而防止其被热损坏。 因此，该设备可以长期保持运行，并且可以使用纤维增强的片材预浸料的质量高得多，并且可以进一步延迟浸渍树脂的劣化。
