섬유 강화 수지 재료로 이루어지고, 경량화와 뛰어난 강도를 양립할 수 있는 중공 구조체를 제공한다. 제 1 강화 섬유와 제 1 매트릭스 수지를 함유하는 제 1 섬유 강화 수지 재료로 이루어지는 제 1 성형체와 제 2 강화 섬유와 제 2 매트릭스 수지를 함유하는 제 2 섬유 강화 수지 재료로 이루어지는 제 2 성형체와 결합되어 지고 중공 구조를 갖는 중공 구조체로서, 상기 중공 구조체의 축 방향에 대해 수직 방향의 임의의 단면에 있어서 상기 제 1 성형체의 구조의 압축 강도 Sc 및 상기 제 2 성형체의 구조의 인장 강도 St의 비 Sc / St가 다음 식 (1)을 만족하는 것을 특징으로 하는 중공 구조체. (σc / σt) × (Hc / Ht) <(Sc / St) <(σt / σc) × (Hc / Ht) (1)

    A hollow structure body capable of balancing weight reduction and excellent strength, the hollow structure constituted by a fiber-reinforced resin material, is provided. The hollow structure body has a hollow structure, in which a first shaped product constituted by a first fiber-reinforced resin material containing first reinforcing fibers and a first matrix resin and a second shaped product constituted by a second fiber-reinforced resin material containing second reinforcing fibers and a second matrix resin are combined, wherein in an arbitrary cross section in a direction perpendicular to an axial direction of the hollow structure, a ratio Sc/ St between compressive strength Sc of a structure in the first shaped product and tensile strength St of a structure in the second shaped product satisfies formula (1): Ãc / Ãt * Hc / Ht < Sc / St < Ãt / Ãc * Hc / Ht
