To further reduce a weight of a sandwich structure used as a structural component for a small aircraft such as air mobility.SOLUTION: There is provided a sandwich structure that is a structure in which a honeycomb core or a foam core is sandwiched on both sides with at least one layer of carbon fiber reinforced plastic. The sandwich structure has a thickness of the one layer of carbon fiber reinforced plastic of 0.05 mm or more and 0.15 mm or less, and a thermosetting resin is directly bonded to the honeycomb core or foam core without interposing any other layer between the thermosetting resin as a matrix reinforced with carbon fibers contained in the carbon fiber reinforced plastic and the honeycomb core or foam core.SELECTED DRAWING: Figure 1

    【課題】空モビリティのような小型の航空機の構造部材として用いられるサンドイッチ構造体を一層軽量化することである。【解決手段】サンドイッチ構造体は、ハニカムコア又はフォームコアの両側をそれぞれ少なくとも一層の炭素繊維強化プラスチックで挟んだものである。このサンドイッチ構造体は、前記炭素繊維強化プラスチックの一層の厚さが0.05mm以上0.15mm以下であり、かつ前記炭素繊維強化プラスチックに含まれる炭素繊維で強化されたマトリクスとしての熱硬化性樹脂と前記ハニカムコア又はフォームコアとの間に他の層を介在させずに、前記熱硬化性樹脂が前記ハニカムコア又はフォームコアに直接接合している。【選択図】 図1
