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.
