The invention provides an inflatable unfolding composite material structure capable of being stiffened. The inflatable unfolding composite material structure is composed of an inner container, a composite material, a heating piece and an end cover. The inflatable unfolding composite material structure is folded in a specific folding mode, the cross section of the inflatable unfolding composite material structure is divided into three parts, the outermost layer is the heating piece, the outer layer is the composite material, the inner layer is the inner container, the inner container is made ofa high-molecular polymer material, and the composite material is composed of a base material and a reinforcing material. According to the inflatable unfolding composite material structure, the designable heating piece is attached to a crease area, in the folding and unfolding process, the heating piece is heated, and an unlocking state is provided, after unfolding is completed, the heating pieceis cooled, a locking state is provided, and the influence of creases on folds and stress concentration after unfolding is eliminated. The inflatable unfolding composite material structure has the advantages of being excellent in performance, simple in structure, high in designability, high in rigidity, integrated in rigidity and flexibility, good in structural stability, high in unfolding shape precision and high in reliability, and therefore the inflatable unfolding composite material structure has very good engineering application value.
本发明提供一种可刚化的充气展开复合材料结构,由内胆、复合材料、加热片、端盖构成。充气展开复合材料结构通过特定的折叠方式进行折叠,横截面分为三部分,最外层为加热片,外层为复合材料,内层为内胆,内胆的材质为高分子聚合物材料,复合材料的组分为基体材料和增强材料。本发明的充气展开复合材料结构在折痕区域贴上具有可设计性的加热片,在折叠展开过程加热加热片处于开锁状态,展开完成冷却加热片处于锁定状态,消除了折痕对展开后的褶皱与应力集中影响。本发明的充气展开复合材料结构具有性能优越、结构简单、可设计性强、刚度大、刚柔结合、结构稳定性好、展开形状精度高、可靠性较高的优点,因此,本发明有非常好的工程应用价值。
