As a new high-tech material, carbon fiber has higher cost than traditional metal materials, but it has special significance in improving product performance and accelerating industrial upgrading. The State Council issued the "Notice on Made in China 2025" clearly stated high-end CNC machine tools and robots, aerospace equipment, offshore engineering equipment and high-tech ships, advanced rail transit equipment, energy-saving and new energy vehicles, power equipment, agricultural machinery and equipment, and biology. In the key development areas such as medicine and high-performance medical equipment, carbon fiber materials have different forms of application in these fields.

1. 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.

Second, agricultural machinery and equipment

China Manufacturing 2025 Strategy requires the development of advanced agricultural machinery and equipment used in major production processes such as breeding, cultivation, planting, management, transportation, transportation and storage of bulk grain and strategic economic crops, accelerating the development of high-end agricultural equipment and key core components, and improving Agricultural machinery equipment information collection, intelligent decision-making and precision operation capabilities.

As a large agricultural country, how to focus and effectively detect the growth of crops and spraying pesticides is one of the problems that high-end agricultural equipment is actively solving. It has the advantages of saving pesticides, high precision, and good control effect. The agricultural plant protection machine can be operated remotely. The way to help spray workers avoid direct contact with pesticides, improve the safety of spraying operations, and reduce resource costs to a large extent in a more precise way. UAVs for agricultural monitoring can timely and accurately grasp the growth of crops and provide reliable information for agricultural measures.

Carbon fiber composite materials such as carbon fiber blades, carbon fiber casings, and carbon fiber wall tubes have become mainstream materials for the manufacture of unmanned plant protection machines. Carbon fiber material with a specific gravity of only one quarter of steel, good flexibility, high specific strength, tensile strength is more than 10 times that of ordinary steel, excellent creep resistance and shock resistance, and good durability and durability. Corrosive, it has a certain tolerance to acid, alkali, salt and atmospheric corrosion, which can effectively extend the service life of the drone.
