    摘要: The thickness of a fiber-reinforced resin sheet having uniformly distributed and substantially unidirectional fibers is reduced by stretching a fiber-reinforced resin sheet starting material in intimate contact with a thermoplastic sheet having a tensile strength larger than the fiber-reinforced resin sheet. This is accomplished by heating the fiber-reinforced resin sheet at a temperature at which the resin in the fiber-reinforced resin becomes sticky and subjecting the sheets to a uniform compressive force to adhere the fiber-reinforced sheet to the thermoplastic resin sheet and then simultaneously stretching the thus-adhered sheets to form a thin fiber-reinforced sheet in which the direction of stretching is perpendicular to the direction of the fibers.

    摘要: The present invention relates to a process for the continuous production of prepreg sheets unidirectionally arranged in parallel which involves contacting a plurality of fiber bundles arranged unidirectionally in parallel with each other with a solvent and continuously taking up the individual fiber bundle units under tension over curved surfaces of spreader bodies, such as cylinders while in a wet state, thereby spreading out said fiber bundles over the curved surfaces by means of said tension and subsequently drying the thus-spread out fibers. The invention also contemplates impregnating the dried fiber bundles with a specified quantity of molten resin to prepare the final prepreg resin-containing sheets. According to applicants' method, the fiber bundles are spread with a solvent prior to being impregnated with a resin and this method greatly decreases the frictional resistance between the fiber bundles and the curved surfaces making it possible for the fiber bundles to be spread out by only using a slight tension.
