The invention relates to a sandwich structure. The purpose of the present invention is to further reduce a sandwich structure used as a structural member of a small aircraft such as an air moving tool. The sandwich structure body is a structure body obtained by clamping the two sides of a honeycomb core or a foam core with at least one layer of carbon fiber reinforced plastic respectively. In the sandwich structure, the thickness of one layer of the carbon fiber reinforced plastic is 0.05 mm or more and 0.15 mm or less, and no other layer is sandwiched between the honeycomb core or the foam core and a thermosetting resin as a matrix reinforced by carbon fibers contained in the carbon fiber reinforced plastic, and the thermosetting resin is directly bonded to the honeycomb core or the foam core.
本发明涉及夹层结构体,目的在于进一步减轻用作空中移动工具那样的小型航空器的结构部件的夹层结构体。夹层结构体是将蜂窝芯或泡沫芯的两侧分别用至少一层碳纤维增强塑料夹住而得到的结构体。在该夹层结构体中,一层所述碳纤维增强塑料的厚度为0.05mm以上且0.15mm以下,并且由所述碳纤维增强塑料中包含的碳纤维增强的作为基体的热固性树脂与所述蜂窝芯或泡沫芯之间不夹入其他层,所述热固性树脂直接与所述蜂窝芯或泡沫芯接合。
