To provide a composite structure that has a low expansion coefficient and a high specific rigidity.SOLUTION: In a composite structure, a plurality of ribs 6b made of carbon fiber reinforced plastic for supporting skins 6a are provided in the portions where there is no aluminum honeycomb 7 between the skins 6a of a frame 6 made of carbon fiber reinforced plastic. The skins 6a include a portion in which the fiber direction of the carbon fiber reinforced plastic for constituting the skin 6a is in a direction in which thermal expansion of the aluminum honeycomb 7 is suppressed, and the rib 6b includes a portion in which the fiber direction of the carbon fiber reinforced plastic for constituting the rib 6b corresponds to the stand-up direction of the rib 6b.SELECTED DRAWING: Figure 3
【課題】低膨張率かつ比剛性の高い複合構造体を提供する。【解決手段】複合構造体は、炭素繊維強化プラスチック製の枠体6のスキン6aの間のアルミハニカム7のない部分に、スキン6aを支持する炭素繊維強化プラスチック製のリブ6bを複数設けている。スキン6aは、それを構成する炭素繊維強化プラスチックの繊維方向が、アルミハニカム7の熱膨張を抑制する方向となる部分を含み、リブ6bは、それを構成する炭素繊維強化プラスチックの繊維方向がリブ6bの起立方向に一致する部分を含む。【選択図】図3
