To achieve weight savings and reduced manufacturing time in coupled parts with complex shapes in aircraft structures.SOLUTION: The present invention includes: a hot-press process (S200) in which a first thermoplastic composite material including first reinforcing fibers is hot-press molded to produce a first intermediate material having a main structural region in which the first reinforcing fibers are arranged to extend along a direction corresponding to a main load direction acting on the joint component; an injection molding process (S300) to produce a second intermediate material having a complex structural region and a main structural region made of a second thermoplastic composite material by injection molding the second thermoplastic composite material containing second reinforcing fibers shorter than the first reinforcing fibers and bonding it to an end face of the first intermediate material; a fusion bonding process (S400) in which end faces of a plurality of second intermediate materials to each other to produce a joint part having a hollow structure.SELECTED DRAWING: Figure 5
【課題】航空機構造の複雑な形状を有する結合部品において、軽量化および製造時間の短縮を達成する。【解決手段】第1強化繊維を含む第1熱可塑性複合材料をホットプレス成型することにより、結合部品に作用する主荷重方向に対応する方向に沿って第1強化繊維が延びるように配置された主構造領域を有する第1中間材を製造するホットプレス工程(S200)と、第1強化繊維よりも短い第2強化繊維を含む第2熱可塑性複合材料を射出成型して、第1中間材の端部に接合することにより、第2熱可塑性複合材料からなる複雑構造領域と主構造領域とが接合された第2中間材を製造する射出成型工程(S300)と、複数の第2中間材の端面を相互に融着することにより、中空構造を有する結合部品を製造する融着工程(S400)と、を含む。【選択図】図5
