To provide composite spars with integrated sacrificial surfaces.SOLUTION: Composite assemblies are described that include composite spars that are co-cured with one or more sacrificial members on their flanges, forming an integrated sacrificial surface for the composite spars. In one embodiment, the composite assembly includes a composite spar having a web and flanges that project from sides of the web. The composite assembly further includes a sacrificial member of composite materials co-cured with the composite spar on an outer surface of at least one of the flanges. In addition, the sacrificial member has an outer surface that has been machined into conformance with an inner surface of at least one skin panel for an aircraft structure to form a contact surface with the at least one skin panel.SELECTED DRAWING: Figure 2

    【課題】一体化された犠牲表面を備えた複合スパーを提供する。【解決手段】フランジ上の1つ又は複数の犠牲部材と共硬化されて、複合スパー用の一体化された犠牲表面が形成される、複合スパーを含む複合アセンブリが説明されている。一実施形態では、複合アセンブリは、ウェブと、ウェブの側面から突出するフランジとを有する複合スパーを含む。複合アセンブリは、フランジの少なくとも1つの外面上に複合スパーと共硬化された複合材料の犠牲部材を更に含む。更に、犠牲部材は、少なくとも1つのスキンパネルとの接触面を形成するように、航空機構造用の少なくとも1つのスキンパネルの内面に一致するように機械加工された外面を有する。【選択図】図2
