The invention relates to a corrugated structure-based sliding type flexible composite material skin. The corrugated structure-based sliding type flexible composite material skin is composed of a composite material corrugated plate, composite material thin plates and an elastomer layer. The connection relations of the composite material corrugated plate, the composite material thin plates and the elastomer layer are as follows: the composite material thin plates are bonded on the horizontal cementing surfaces of the composite material corrugated plate; the left side of each composite material thin plate is cemented on a corresponding horizontal cementing surface at a wave crest, and is in lap joint with one composite material thin plate at an adjacent wave crest at the right side; and the elastomer layer is tightly attached to the composite material thin plates. The characteristic that the composite corrugated plate has large rigidity in a corrugated direction and the characteristic that the composite thin plates have large out-of-plane rigidity are combined, and therefore, a large deformation function can be achieved, out-of-plane aerodynamic loads can be resisted. The corrugated structure-based sliding type flexible composite material skin has the advantages of simple structure and low weight. The flexible skin scheme for a morphing wing is practical and feasible.

    一种基于波纹结构的滑动式柔性复合材料蒙皮,由复合材料波纹板、复合材料薄板和弹性体层组成。其连接关系如下:复合材料薄板粘接在复合材料波纹板的水平胶结面上,复合材料薄板左侧胶接在波峰处的水平胶接面上,搭接在右侧相邻波峰处的复合材料薄板上,弹性体层紧密贴合在复合材料薄板上。本发明将复合材料波纹板在波纹方向上具有大刚度和复合材料薄板具有大面外刚度的特点结合起来,能够实现大变形功能,且能抵抗面外气动载荷,具有结构简单和重量轻的有点,是一种实用可行的变体机翼柔性蒙皮方案。
