  • Tape-shaped prepreg and a method for production thereof
    Patent number: 11938655
    Abstract: The invention aims to provide a tape-shaped prepreg including unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and being high in handleability during molding and high in adhesiveness to other members. The tape-shaped prepreg includes unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and has an arithmetic average roughness (Ra) of 0.
    Type: Grant

  • UNIDIRECTIONALLY-ORIENTED TAPE-SHAPED PREPREG, AND MOLDED ARTICLE THEREOF
    Publication number: 20200131325
    Abstract: A tape-shaped prepreg includes unidirectionally-oriented reinforcing fibers, and a thermoplastic resin, which prepreg has a good and uniform tape thickness and tensile strength, and which allows for producing a final product at a low cost. The tape-shaped prepreg includes unidirectionally-oriented reinforcing fibers and a thermoplastic resin composition, and has an average thickness of 0.2 mm or more and 1.5 mm or less, a void content of 5% by volume or less, and a degree of dispersity of reinforcing fibers of 0.5 or less.
