To provide a component for an aircraft made of a composite material, which can be efficiently manufactured without use of autoclave molding and which has a curved structure.SOLUTION: A component for an aircraft made of a composite material has a laminated structure in which a plurality of composite material layers are stacked, and has a curved structure having a peripheral length difference in a longitudinal direction. The laminated structure is held in the whole component including the curved structure. In each composite material layer, a reinforcement fiber is made of a single continuous fiber that does not include a joint part, and a partial slit part is included. In addition, an open slit part, in which the slit part is in an open state, is included in the reinforcement fiber.SELECTED DRAWING: Figure 5
【課題】 オートクレーブ成形を用いることなく、効率的に製造することが可能な、湾曲構造を有する複合材料製航空機用部品を提供する。【解決手段】 複合材料製航空機用部品は、複合材料層が複数積層された積層構造を有するとともに、長手方向に周長差を有する湾曲構造を有する。積層構造は、湾曲構造を含む部品全体において保持される。それぞれの複合材料層では、強化繊維が、接合部を含まない単一の連続繊維で構成され、かつ、部分的な切込部を含み、さらに、強化繊維には、前記切込部が開いた状態である開切込部が含まれている。【選択図】 図5
