Serviceability Properties of Solid Buoyancy Materials for Deep-Sea HOV

Studying the evolution characteristics of damage strength and water absorption behavior hollow glass beads solid buoyancy materials used for manned submersibles in hyper-pressure environment will help people to understand mechanism induced submersibles. To explore influence different pressure, temperature, loading rate load cycle times on deformation, failure, buoyant materials, hydrostatic pressure tests under conditions are conducted this study. Based test data, nonlinear mechanical properties two obtained. The results show that affected by increase exponentially as increases. insignificantly affects compressive both materials. Ambient temperature has a great failure high-strength After cyclic loading, decreased, X-ray micro-CT showed internal had good shape no significant change breakage rate. material is mainly due resin base properties, resulting aging performance attenuation. research helpful further fracturing then play guiding role calculating counterweight submersible operation prediction maintenance
