    摘要: A male joint includes a male joint main body and a valve element provided coaxially with a central axis of the male joint main body. The valve element includes a shaft portion and a valve portion coaxially provided at a tip end of the shaft portion. The valve portion has a first surface intersecting with the central axis and a second surface that is connected to an outer edge of the first surface and extends along the central axis from the first surface to a base end at a base end portion. The valve portion further comprising a groove having an annular shape centered on the central axis at a side portion and a deformation portion on a base end side of the groove.

    摘要: Provided are a composite material that adequately obtains the effect of carbon nanotubes, a prepreg in which the composite material is used, a carbon-fiber-reinforced molded article having greater resistance to the progression of the interlayer peeling crack, and a method for manufacturing the composite material. A composite material includes a carbon fiber bundle in which a plurality of continuous carbon fibers are arranged, carbon nanotubes adhering to respective surfaces of the carbon fibers, and a plurality of fixing resin parts partly fixing the carbon nanotubes on the surfaces of the carbon fibers, where the fixing resin parts cover 7% or more and 30% or less of the surfaces of the carbon fibers to which the carbon nanotubes adhere.
