英文摘要： The deep-sea buoyancy material is key marine engineering material for ocean development, ocean exploration, marine engineering equipment installation and maintenance as well as offshore oil drilling and other areas. This study is mainly designed for optimizing materials system of deep-sea buoyancy material (for solving the contradiction of low density and high strength), analyzing the compression damage mechanism of deep-sea buoyancy material and the dynamic compression deformation behavior under hydrostatic pressure (simulated deep-sea environmental conditions), building a simulation environment performance evaluation methods of seep-sea buoyancy material and study the reliability analysis methods of application, establishing the damage failure mode of deep-sea buoyancy material and their factors, and then establishing microscopic damage mechanism of the buoyancy material. Based on the study of simulation dynamic compression behavior of deep-sea buoyancy material, the dynamic damage mechanism of the buoyancy material under simulated environmental conditions and reliability analysis methods of service will be revealed. This study could provide the theoretical foundation for the development, production, application of deep-sea buoyancy material and provide protection for reliability applications of buoyancy material.
