Carbon Fiber Materials for Compressive Structures

Carbon fiber materials have become an ideal choice for compressive structures of deep-sea submersibles due to their excellent properties such as low density, high strength, fatigue resistance, and corrosion resistance.

China's unique ultra strong carbon fiber submarine can easily withstand enormous pressure in the deep sea of 6000 meters. The diving ability at this depth far exceeds that of any active nuclear submarine. The hull of the new submarine, with a wall thickness of only 3 centimeters, can withstand a water pressure of up to 90 megapascals, more than twice that of the previous Titan submersible. The breakthrough of this technology is due to the in-depth research and innovation of Chinese scientists in the water pressure resistance, low temperature resistance and other properties of carbon fiber composite materials.
