  • Publication number: 20210108042
    Abstract: A fiber-reinforced resin prepreg and a molded article obtained by molding a molding material including the fiber-reinforced resin prepreg are described. The fiber-reinforced resin prepreg contains a carbon fiber bundle and a matrix resin composition. The ipa value of the carbon fiber bundle measured by an electrochemical measurement method is 0.14 ?A/cm2 or more. The impact strength of a film obtained by solidifying the matrix resin composition under particular molding conditions is 12.0 kJ/m or more.

  • Publication number: 20200377681
    Abstract: Provided is a fiber-reinforced thermoplastic resin prepreg which exhibits high interfacial adhesion between reinforcement fibers and a matrix resin, while having excellent interlaminar fracture resistance. The fiber-reinforced thermoplastic resin prepreg of the present invention comprises: a matrix resin comprising a polyarylketone resin and a polyetherimide resin; and a carbon fiber, wherein the polyetherimide resin in the matrix resin comprises a polyetherimide resin having a structural unit represented by Formula (1), an amount of the polyetherimide resin in the matrix resin (100% by mass) is 3% by mass to 25% by mass, and an amount of the polyarylketone resin in the matrix resin (100% by mass) is 75% by mass or more.
