The invention discloses a reinforced composite sandwich shell suitable for a large-depth underwater vehicle, and belongs to the technical field of pressure-resistant shells of underwater vehicles, the reinforced composite sandwich shell comprises a first shell and a second shell, the first shell sleeves the outer side of the second shell, a net-shaped sandwich reinforcing layer is arranged between the first shell and the second shell, and the net-shaped sandwich reinforcing layer is arranged between the first shell and the second shell. The net-shaped sandwich reinforcing layer comprises at least one first reinforcing rib and at least one second reinforcing rib, the at least one first reinforcing rib and the at least one second reinforcing rib intersect with each other to form a net-shaped structure, and the at least one first reinforcing rib and/or the at least one second reinforcing rib cling to the inner wall face of the first shell and the outer wall face of the second shell at the same time. According to the reinforced composite sandwich shell suitable for the large-depth underwater vehicle, the buckling resistance of the shell can be remarkably improved, the phenomenon that delamination or instability is generated among all layers of structures of the shell when the shell bears the radial external pressure effect is avoided, and then the rigidity of the shell is effectively improved.
本发明公开了一种适用于大深度潜航器的增强复合夹芯壳,属于潜航器的耐压壳技术领域,包括第一壳体和第二壳体,第一壳体套设在第二壳体外侧,第一壳体和第二壳体之间设置有网状夹芯加强层,网状夹芯加强层包括至少一个第一加强筋和至少一个第二加强筋,至少一个第一加强筋和至少一个第二加强筋相互交叉,形成网状结构:且至少一个第一加强筋和/或至少一个第二加强筋同时紧贴第一壳体的内壁面和第二壳体的外壁面。本发明提供了一种适用于大深度潜航器的增强复合夹芯壳,其能够显著提升壳体的抗屈曲能力,避免壳体在承受径向外压作用时,壳体各层结构之间产生脱层或失稳的现象,进而有效提升该壳体的刚度。
