    Abstract: A method for manufacturing a structure material is a method for manufacturing a structure material that includes a thermoplastic resin, reinforced fibers, and voids. The method includes: a first process for arranging a structure precursor comprising the thermoplastic resin and the reinforced fibers in a mold with a surface temperature of 80° C. or less; a second process for raising the surface temperature of the mold up to a temperature at which a storage elastic modulus (G′) of the structure precursor is less than 1.2×108 Pa; a third process for lowering the surface temperature of the mold down to a temperature at which the storage elastic modulus (G′) of the structure precursor is 1.2×108 Pa or more; and a fourth process for removing a structure material obtained after end of the third process from the mold.

    Abstract: Provided is a structure having excellent flexibility represented by elastic restoring from compression or tensile elongation at break, and excellent lightness. A structure according to the present invention includes reinforced fibers, first plastic, and second plastic that exhibits rubber elasticity at room temperature, the reinforced fibers being discontinuous fibers, and the first plastic and/or the second plastic coating a crossing point between the reinforced fibers in contact with each other.
