Abstract: A sandwich laminate, includes as a layer forming a core, a sheet-form intermediate substrate obtained by impregnating a mat composed of reinforcement fibers with a thermoplastic resin; and, as layers forming a skin, sheet-form intermediate substrates obtained by impregnating a mat composed of reinforcement fibers or continuous reinforcement fibers with a thermoplastic resin, wherein at least the sheet-form intermediate substrate used as the layer forming a core has a thermal expansibility, the usable temperature region of a thermoplastic resin (A) constituting the layers forming a skin and that of a thermoplastic resin (B) constituting the layer forming a core overlap each other over a temperature range of at least 5° C., and the thermoplastic resin (A) has a temperature region where it does not melt at a lower limit of the usable temperature region of the thermoplastic resin (B).

Abstract: A method is described for manufacturing a molded product having a recessed/protruding part from a molded substrate (A) including reinforcing fibers and a matrix resin by press molding, the method comprising: a step (I) of placing the molded substrate (A) between molds including an upper mold and a lower mold and deforming the molded substrate (A) in an in-plane direction by heating and pressing the molds; and a step (II) of deforming the molded substrate (A) in an out-of-plane direction by depressurizing the molds subsequent to the step (I), wherein a deformation rate ratio T represented by the following formula (1) is within a range of 0.1 to 1: T=X/Z (1) where X and Z are as defined.

Abstract: A structure material includes a resin, reinforced fibers, and voids. The structure material includes a volume content of the resin being within a range of 2.5% by volume or more and 85% by volume or less, a volume content of the reinforced fibers being within a range of 0.5% by volume or more and 55% by volume or less, the voids being contained in the structure material in a rate within a range of 10% by volume or more and 97% by volume or less, a thickness St of the structure material satisfying a conditional expression: St≥Lf2·(1−cos(θf)), and a specific bending modulus of the structure material represented as Ec1/3·ρ−1 being within a range of 3 or more and 20 or less, and a bending modulus Ec of the structure material being 3 GPa or more.
