PROBLEM TO BE SOLVED: To provide a method of manufacturing a body structure for a spacecraft, which reliably protects a spacecraft body against vibrations and impacts at a launch, and which achieves significant weight saving and manufacturing cost reduction.SOLUTION: A method of manufacturing a body structure for a spacecraft includes: a cutting step (S1) of cutting a fiber-reinforced resin prepreg or semi-preg laminate into each of a shape of a first regular-hexagonal main plate constituting a shell, shapes of three second regular-hexagonal main plates and shapes of three square auxiliary plates; a first press step (S2) of molding the shell by heating and pressurizing the cut laminate by a molding tool so that the second main plates and the auxiliary plates can be circumferentially and alternately connected to sides of the first main plate, respectively; and a joining step (S5) of joining joint surfaces of the pair of shells molded in the first press step.

    【課題】打上時の振動や衝撃から宇宙機本体を確実に保護し、大幅な軽量化と製造コストの削減を実現した宇宙機用構体の製造方法を提供する。【解決手段】宇宙機用構体の製造方法は、繊維強化樹脂のプリプレグ又はセミプレグの積層体を、殻を構成する正六角形の第1主板、3枚の正六角形の第2主板、及び3枚の正方形の副板それぞれの形状に裁断する裁断工程(S1)と、第1主板の各辺に第2主板及び副板が周方向に交互に接続されるように、裁断された積層体を成形型により加熱及び加圧して殻を成形する第1プレス工程(S2)と、第1プレス工程で成形された一対の殻の接合面同士を接合する接合工程(S5)とを含む。【選択図】図2
