1. eVTOL
Carbon fiber is the main body structure material of eVTOL and meets the requirements of lightweight and high strength. Current mainstream eVTOL design solutions use carbon fiber as the main body structure material, and more than 90% of the composite materials used are carbon fiber. From the perspective of composite application scenarios, about 75-80% are used in structural components and propulsion systems, followed by internal applications such as beams and seat structures accounting for 12-14%, and battery systems, avionics equipment and other small applications accounting for 8 -12%. Judging from the design plans announced by EHang Intelligent, Xpeng Huitian, Fengfei Aviation and other leading eVTOL manufacturers in China, the fuselage structures are all made of carbon fiber composite materials, and the rotor blades of Xpeng Huitian Voyager X2 and The landing gear is also made of carbon fiber composite. According to calculations, the demand for carbon fiber for a single eVTOL is between 100-400kg. According to data from Cirium, as of May 23, global eVTOL orders are approximately 6,300. Assuming that they are all released before 2030, it is expected to drive demand for thousands of tons.
2. Sports and leisure
In the sports and leisure market, carbon fiber is mainly used in high-end sports and leisure markets such as golf clubs, hockey sticks, tennis rackets, fishing rods, bicycle frames, skis, and rowing boats. The application of this block is mainly based on the lightweight, high strength, high modulus, corrosion resistance and other characteristics of carbon fiber. For example, golf clubs made of carbon fiber composite materials are nearly 50% lighter than metal clubs, and carbon fiber bicycles are 40% lighter than aluminum materials and achieve higher frame accuracy. Carbon fiber for fishing rods, rackets, skis, golf clubs and other sporting goods mostly use large tow carbon fiber (≥24K). In Asia, more carbon fiber is used to make athleisure products than in any other region in the world. In Asia, especially in China, carbon fiber is increasingly used to make tubular composite objects such as golf clubs and tennis rackets, and other sporting goods include fishing poles, arrowheads, ski equipment, racing cars, bicycle frames, rackets, and baseball bats. and sports walls.
3. Musical instruments
Traditional wooden violins generally need to be stored under constant temperature and humidity conditions, and the temperature and humidity should not be too high. Even then, wooden violins will crack and corrode due to the action of moisture and microorganisms in the air, and their acoustic quality will increase over time. Severe decline. Carbon fiber violins can avoid these shortcomings of wooden violins, mainly because carbon fiber composite materials have the characteristics of high temperature resistance, corrosion resistance, moisture resistance, dimensional stability and antimicrobial properties. If made of carbon fiber, the violin's tone can still be maintained for a long time. Very good original features. The resonance soundboard is an important part of the piano. It plays a role in resonating, beautifying and radiating the vibrating sound of the strings. Traditional piano solid wood soundboards mainly include solid wood soundboards and three-layer solid wood composite soundboards. The former is extremely demanding in material selection, such as wood. The number of natural defects contained, the texture color difference between woods, the growth ring width and variation coefficient of wood have extremely high requirements, and the stability is poor; the latter reduces the requirements for material selection, and the dimensional stability has improved, but it still exists Shortcomings include low material yield and poor vibration uniformity of the entire soundboard. At present, soundboards made of carbon fiber composite materials have good vibration conductivity and mechanical properties, dimensional stability and stable pronunciation effect. The vibration of the soundboard is spread evenly in all directions, and the cost is reduced.
