High-Performance Carbon Fiber Tube

Deep-Sea Exploration Carbon Fiber Pressure Hulls

Oceanographic Breakthrough Technology Engineered for 11,000m hadal zone operations, our filament-wound carbon tubes withstand 114MPa external pressure - equivalent to Mariana Trench conditions. Using a patented hybrid architecture of T800S carbon fibers and basalt fiber reinforcement, we achieve 18% improved implosion resistance compared to titanium alloys.
