Research on key technologies of deep diving submersible material development
The paper guided by the application requirements of deep diving submersible materials,the application status and development trend of the main pressure-resistant shell materials and solid buoyancy materials in various countries are deeply studied.By comparing and analyzing the mechanical properties,chemical components,and other indicators of materi-als,a series of technical bottlenecks encountered in the development of current deep submergence materials and correspond-ing solutions are proposed.Through in-depth analysis of key technologies and performance indicators of deep diving materi-als in various countries,it is found that their overall trend is towards high strength and low density.However,further improv-ing the performance indicators of materials leads to a series of defects such as lower toughness,poor welding performance,and higher water absorption.Therefore,try to develop new materials such as hollow ceramics and nanocomposites with ex-cellent performance.The ceramic composites and carbon nanotube-reinforced buoyancy materials,with their excellent struc-tural strength and compression resistance,will greatly improve the overall performance index of deep submergence equip-ment and become important materials for building deep submersibles in the future.
