    摘要： A method of manufacturing a composite includes bringing a first surface of a first base in which a first fiber base that is to constitute the first base is impregnated with a first resin into contact with a second surface of a second base in which a second fiber base that is to constitute the second base is not impregnated with a second resin, and impregnating the second fiber base with a portion of the first resin with which the first fiber base is impregnated.

    摘要： Provided are a continuous fiber-reinforced resin molding having high adhesion and compatibility in an interface between continuous reinforcing fibers and a synthetic resin, and in which a low occurrence of voids in the interface and adequate strength can be realized, and a method for manufacturing the same. A continuous fiber-reinforced resin molding comprising a synthetic resin and continuous reinforcing fibers having a substantially circular cross section, the continuous fiber-reinforced molding being characterized in that the number of continuous reinforcing fibers where the porosity in a peripheral-edge region separated by one tenth the radius of a single continuous reinforcing fiber from the peripheral edge part of the continuous reinforcing fibers in the interface between the synthetic resin and the single continuous reinforcing fiber in a cross section orthogonal to the length direction of the continuous reinforcing fibers is at least 10% of the total number of continuous reinforcing fibers.

    摘要： A production method for a fiber-reinforced resin molded object is provided whereby a large apparatus is not used when molding, by heating and pressing, a fiber-reinforced resin base material that includes a matrix resin, a molded object with excellent precision and quality can be obtained, and for which work is simple.
    The production method includes arranging, on an inner surface of a lower mold 3, a fiber-reinforced resin base material 1 obtained by impregnating a matrix resin into reinforcing fibers; filling a core space 5 of the mold, in which the fiber-reinforced resin base material 1 is arranged, with a powder mixture 2a that has liquidity and that includes thermally expandable microcapsules and another powder; sealing the lower mold 3 and an upper mold 4; heating at from a heat expansion starting temperature to a maximum expansion temperature of the thermally expandable microcapsules to cause the thermally expandable microcapsules to expand; and pressing the fiber-reinforced resin base material 1 against the inner surface of the lower mold 3 to produce a molded object.
