Research Progress of Lightweight Marine Buoyancy Materials
"A strong maritime nation"is a major strategic task for realizing China's national rejuvenation.Buoyancy materials,as one of the key auxiliary materials for the exploitation of marine resources,have the characteristics of low density,high strength,low water absorption and resistance to hydrostatic external pressure.However,the requirements for buoyancy materials in different ocean depths are slightly different.Therefore,this paper briefly introduced the advantages,shortcomings,applicability and developments of natural buoyancy materials,chemical buoyancy composites,hollow glass microsphere buoyancy composites,ceramic micro-beaded buoyancy composites,metal-matrix buoyancy composites,and so on.Multi-functional composite is a major development direction of buoyancy materials,such as cushioning,high and low temperature resistance,shielding wave absorption,high flame retardancy and low dielectric constant.The research progresses and application ranges of buoyancy materials in lightweight,water absorption,mechanics and temperature resistance were introduced,such as the 10 000-meter-level manned submersible("Struggler"),1 000-meter-level intelligent deep-water drilling platform("Deep Blue Exploration"),100-meter-level deep-sea floating wind power platform("Offshore Guanlan"),ocean-surface buoys of navigation satellite systems.
