  • Publication number: 20240400453
    Abstract: Provided is a concrete reinforcing composite material that is impregnated with a thermoplastic resin having excellent alkali resistance and handleability. In a concrete reinforcing composite material 10, a core material 12 is formed from a fiber bundle of reinforcing fibers. The core material 12 is covered with a coating layer 14 made of a thermoplastic resin. The core material 12 is impregnated with the thermoplastic resin. The thickness of the coating layer 14 is 84 ?m or more. The fiber volume content Vf of the core material 12 is 60% or more.

  • Patent number: 11603442
    Abstract: An object of the present invention is to provide a fiber-reinforced thermoplastic resin sheet which can be manufactured into a molded body exhibiting excellent appearance quality as well as exhibits both high moldability and strength and a manufacturing method of such a fiber-reinforced thermoplastic resin sheet. The present invention relates to a fiber-reinforced thermoplastic resin sheet which is a random laminated body of a tape-shaped unidirectional prepreg and contains spread reinforcement fibers and a polymer (a) and in which the polymer (a) is a polymer of at least a bisphenol A type epoxy compound represented by Formula (1): where n is an integer of 1 to 4 and a bisphenol compound selected from the group consisting of bisphenol A, bisphenol F, bisphenol S, bisphenol B, bisphenol E, and bisphenol P.
