Carbon fiber is known as the "king of new materials" and has excellent mechanical properties and chemical stability. The density is less than 1/4 of steel and the strength is 5 to 7 times that of steel. Ma Tianju, deputy general manager of the ZGHT Pressure Vessel Division, revealed in an interview that the Beidou high-pressure gas cylinders used pure titanium alloys in the early stage, which were very heavy. In the later stages, with the improvement of technology, they used titanium linings. High-strength carbon fiber wound composite, such a cylinder, the product becomes lighter, and the pressure bearing capacity becomes stronger.
