The gas cylinders which are wound by carbon fiber composite materials have the advantages of light weight, strong carrying capacity, good antiknock performance and low manufacturing cost. At present, most commonly used pressure vessels are made of steel, which has great limitations in terms of mechanical properties; for high-pressure vessels, the wall thickness can only be increased to improve the bearing performance. The new carbon fiber composite pressure vessel is made of a thin metal or non-metallic liner and is made of carbon fiber with higher strength. When the pressure cylinder capacity is increased, the weight can be reduced by 50 compared with the same volume of metal gas cylinder. %. In terms of safety performance, the pressure gas cylinder wound by the multi-layer fiber can ensure the safe operation of the gas cylinder and have sufficient time for emergency treatment even if the inner liner leaks. In the production process, the carbon fiber cylinder manufacturing process is much simpler than the complicated process of the steel container. Usually, the special CNC winding machine is used to wind the carbon fiber in the outer layer of the aluminum liner, which has high precision and saves cost.
The application of carbon fiber-wound gas cylinders mainly includes compressed gas cylinders for vehicles, lightweight pressure vessels for aerospace power systems, and high-pressure vessels for gas transportation. In recent years, the market has become more optimistic about the increase in demand for pressure vessels. One of the reasons is the low-cost breakthrough of fuel cells, such as the mass production of Toyota's fuel cell vehicle MIRAI, which will bring strong demand for high-pressure hydrogen cylinders. The second is the shale gas collection industry in Europe and the United States. The transportation and storage of shale gas require safe, stable and economical high-pressure gas cylinders, which will promote the demand for carbon fiber pressure vessels. Although the market for pressure vessels is currently small, it has a large room for growth.
