The invention relates to the technical field of composite materials, in particular to a folding variant light structure and a fold sandwich structure using the same, and the folding variant light structure comprises a flexible layer and a rigid layer fixedly arranged on the upper surface of the flexible layer; the rigid layer comprises a plurality of rigid units which are distributed at intervals in an array mode, each rigid unit comprises two parallelogram blocks which are symmetrically distributed left and right at intervals, and the two parallelogram blocks are distributed in an inverted-V shape. The fold sandwich structure comprises the folding variant light structure, and skin layers are fixedly connected to the upper surface and the lower surface of the folding variant light structure. The stacking structure composed of the flexible layers and the parallelogram blocks is folded to form a rigid-flexible three-dimensional structure, so that the folding structure has the advantages of high strength and light weight, the folding process is simple, the size can be adjusted according to actual requirements, and the application flexibility and convenience of the structure are greatly improved.
本发明涉及复合材料技术领域,具体为折叠变体轻质结构及使用该结构的褶皱夹心结构,折叠变体轻质结构包括柔性层,以及固定设于柔性层上表面的刚性层;刚性层包括若干个间隔阵列分布的刚性单元,刚性单元包括两个左右间隔对称分布的平行四边形块,两个平行四边形块呈倒V字形分布。褶皱夹心结构包括上述的折叠变体轻质结构,折叠变体轻质结构的上表面和下表面均固定连接有蒙皮层。本发明通过将由柔性层和平行四边形块构成的层叠结构折叠,形成刚柔相间的立体结构,具有高强度和轻质化的优点,折叠工艺简单,可以根据实际需求进行尺寸调整,大大提高了结构的应用灵活性和便捷性。
