The invention belongs to the technical field of processing and manufacturing of sandwich composite material pressure-resistant shells, and particularly relates to a sandwich composite material pressure-resistant shell trepanning reinforcing structure and an assembling method thereof. Comprising a built-in reinforcing ring, an inner bushing, an outer bushing, an outer threaded sleeve and a composite material insulating filling layer, the built-in reinforcing ring is nested in the opening of the sandwich composite material pressure-resistant shell; the inner bushing is inserted into the built-in reinforcing ring from the inner side; the outer bushing is inserted into the built-in reinforcing ring from the outer side; the outer threaded sleeve is sequentially inserted into the inner bushing and the outer bushing from outside to inside; according to the invention, the built-in reinforcing ring, the inner bushing, the outer bushing, the outer threaded sleeve and other strength reinforcing structures are arranged at the opening of the sandwich composite material pressure-resistant shell, so that the pre-tightening force of the reinforcing structures on the sandwich composite material can be ensured, and the composite material insulating filling layers are arranged between the metal piece and the upper and lower surface layers of the sandwich structure; and the problem of electrochemical corrosion of the reinforcing structure in a marine environment can be avoided.
本发明属于夹层复合材料耐压壳加工制造技术领域,尤其涉及一种夹层复合材料耐压壳开孔加强结构及其装配方法。包括内置增强环、内衬套、外衬套、外螺纹套筒、复合材料绝缘填充层;内置增强环嵌套在夹层复合材料耐压壳的开孔处;内衬套从内侧插入内置增强环;外衬套从外侧插入内置增强环;外螺纹套筒从外向内依次插入内衬套和外衬套;本发明及其装配方法,通过在夹层复合材料耐压壳体开孔处设置内置增强环、内外衬套与外螺纹套筒等强度加强结构,可确保加强结构对夹层复合材料的预紧力,在金属件与夹层结构上下表层之间设置复合材料绝缘填充层,可避免加强结构在海洋环境下发生电化学腐蚀问题。
