Carbon fiber reinforced resin matrix composites are important materials for the production of weapons and equipment. In fighter jets and helicopters, carbon fiber composites are used for special functional components of the main structure of the aircraft, sub-structures and special parts of the aircraft. Foreign countries have applied carbon fiber/epoxy and carbon fiber/double horse composite materials to the fuselage fuselage, main wing, vertical tail, flat tail and skin, which have played an important role in weight reduction and greatly improved the performance of anti-fatigue and corrosion resistance. The data shows that the front fuselage section with composite structure can reduce the quality by 31.5% compared with the metal structure, reduce the parts by 61.5%, reduce the fastener by 61.3%, and the composite vertical stabilizer can reduce the quality by 32.24%.

High-mode carbon fiber is lightweight, rigid, dimensionally stable, and thermally conductive, so it has long been used in satellite structures, solar panels, and antennas. Expanded solar panels on today's artificial satellites are mostly made of high-mold carbon fiber composite materials, and some key components on the space station and the world's round-trip transportation system often use high-mold carbon fiber composite materials as the main material.

3. Marine engineering equipment and high-tech ships

The "Notice" requires vigorous development of deep sea exploration, resource development and utilization, offshore operations support equipment and its key systems and special equipment. Carbon fiber materials have become an indispensable material for deep sea exploration and deep sea oil development. Carbon fiber umbilical pipe reinforcement rods, anchoring tethers, oil production risers, flexible risers and other structural components are increasingly used in deep sea oil platforms.

The production depth of oil and gas fields is generally above 3000m, and the exploration depth is above 4000m. The structural design of oil and gas fields must meet the 25-year maintenance-free standard. The traditional offshore oil and gas field related materials are steel, such as the tether that anchors the platform to the seabed and the pipe that connects the oil wellhead to the platform. The weight of steel ropes and pipes increases the floating size of the platform and increases energy consumption. Steel is also highly corrosive under seawater immersion. The working life is only two to three years. The cost of periodic maintenance and cable maintenance is extremely high. In contrast, the performance of carbon fiber materials has obvious advantages, such as a working platform of 1500m water depth, steel ropes weigh about 6000t, and the quality of carbon fiber composites is only 1000t. In addition, its high strength, high modulus, excellent fatigue resistance and corrosion resistance make it a working life of more than 25 years, greatly reducing maintenance costs. In high-tech ships, the application of carbon fiber materials is also gradually developed. For example, the development and utilization of carbon fiber ship structural parts such as carbon fiber reinforced concrete watertight cover plates have a significant impact on the speed and energy consumption of ships.

Under this circumstance, the government's strict fuel economy standards and carbon dioxide emission regulations have made it necessary for new energy vehicles to choose carbon fiber composite materials. The weight of electric vehicles is more than 200-300 kg than that of traditional cars. In order to ensure that electric vehicles have better driving range and affordable cost, the weight of electric vehicles must be reduced by more than 50%. Among all lightweight materials, carbon fiber composites are the only advanced materials that can replace steel parts, reduce weight by 50-60%, and provide the same strength.

In addition to the appearance of the cover, bogies, cars, interiors, equipment warehouses, friction materials, battery boxes, etc. are all applications of carbon fiber composites.
