Carbon overwrapped pressure vessels

Carbon overwrapped pressure vessels are a high-performance product that combines advanced material technology with precision manufacturing processes, and play a vital role in many fields.

1. Structure and manufacturing process

This pressure vessel is mainly composed of an inner liner and a carbon fiber winding layer. The inner liner is usually made of metal or high-performance polymer materials, which plays a basic role in sealing and containing the medium. The carbon fiber winding layer is its core feature. Carbon fiber has excellent properties such as high strength, low density, and high modulus. During the manufacturing process, the carbon fiber is tightly wound around the inner liner at a specific angle and number of layers through precise winding equipment. The winding process requires strict control of parameters such as tension and winding angle to ensure that the carbon fiber layer can evenly share the pressure and achieve the best mechanical properties of the structure.

2. Performance advantages

High strength and lightweight

The high strength of carbon fiber enables pressure vessels to withstand extremely high pressures, whether it is storing high-pressure gas or withstanding pressure loads under special working conditions. At the same time, the low density of carbon fiber allows the entire container to be lightweight while ensuring strength. For example, in the aerospace field, reducing every gram of weight has a significant impact on the performance of the aircraft. Carbon overwrapped pressure vessels can reliably store propellants and other media while reducing weight.

Corrosion resistance

Carbon fiber itself has good chemical stability and is not easily corroded. This feature allows the container to be used in some harsh chemical environments, such as when storing corrosive gases or liquids, reducing the risk of corrosion and extending the service life of the container.

Good fatigue performance

Carbon overwrapped pressure vessels show excellent fatigue performance in long-term pressure alternating environments. It can withstand multiple cycles of pressurization and decompression without easily causing structural damage, ensuring safety and reliability during long-term use.

3. Application fields

Aerospace

In spacecraft and aircraft, it is used to store various media such as fuel and oxygen. The lightweight feature helps to improve the payload capacity of spacecraft and the fuel efficiency of aircraft.

Automotive industry

In the field of new energy vehicles, especially hydrogen fuel cell vehicles, it is used to store high-pressure hydrogen. Its high strength and safety meet the needs of the car during driving.

Energy field

In energy-related application scenarios such as natural gas storage and compressed air energy storage, Carbon overwrapped pressure vessels can store energy media efficiently and safely, improving energy utilization efficiency.
