The light composite spherical pressure-resistant structure comprises a hollow ceramic ball lining and a CFRP outer layer, the outer surface of the hollow ceramic ball lining is coated with the CFRP outer layer, and the CFRP outer layer and the hollow ceramic ball lining are matched to form the ceramic-CFRP composite spherical pressure-resistant structure. According to the invention, the hollow ceramic ball lining and the CFRP outer layer are combined, so that the application limitation of single ceramic and single CFRP materials in deep sea engineering is overcome; after underwater implosion occurs, compared with a single ceramic structure, the collapse rate of the ceramic-CFRP composite spherical pressure-resistant structure is obviously slowed down, and a pressure peak curve of a surrounding flow field is also obviously reduced, so that the influence of implosion on the structure and the surrounding flow field is weakened, and a better implosion protection effect is achieved; the structure is simple and clear, the weight reduction effect is remarkable, the multiple effects of safety, light weight and the like are achieved, compared with a traditional pressure-resistant structure, the weight reduction effect is obvious, and therefore the overall cruising ability is improved, and great significance is achieved for design, manufacturing and protection of the deep sea submersible.
本发明提供了一种用于深海内爆防护的轻质复合球形耐压结构及深海潜器,包括空心陶瓷球内衬和CFRP外层,所述CFRP外层包覆在所述空心陶瓷球内衬的外表面,二者配合形成陶瓷‑CFRP复合球形耐压结构。本发明通过空心陶瓷球内衬和CFRP外层相结合,克服了单陶瓷与单CFRP材料在深海工程中应用的局限性;在发生水下内爆后,与单陶瓷结构相比,陶瓷‑CFRP复合球形耐压结构的坍塌速率得到明显减缓,周围流场的压力峰值曲线也得到显著降低,从而削弱了内爆对结构自身及周围流场的影响,具有较好的内爆防护效果;结构简明,减重效果显著,达到了安全性、轻量化等多重功效,相较于传统耐压结构有较明显的减重效果,从而提高整体续航能力,对深海潜器的设计、制造及防护意义重大。
