Advantages of carbon fiber in automobile:
The first advantage of using carbon fiber wheel is lightness. Carbon fiber is a new type of fiber material with high strength and high modulus fiber with carbon content of more than 95%. Its weight is lighter than aluminum, but its strength is higher than steel, with corrosion resistance and high modulus. The carbon fiber wheel has a carbon aluminum two-piece design, all carbon one, and all carbon two-piece design. At present, carbon aluminum two-piece wheels are the most popular in the market. The rims are made of carbon fiber materials, and the spokes are made of lightweight alloy, which is about 35~45% of the same size aluminum alloy wheels.
More energy-saving. According to the data of the automobile research department, every 1kg of unsprung mass reduction is equal to 10kg of unsprung mass reduction. Every 10% reduction of the body can reduce 5-6% of the fuel consumption and 6-8% of the emissions. The use of carbon fiber wheels is 60% of the weight of forged aluminum alloy rims of the same size. Therefore, the weight reduction of the body is also of great significance to environmental protection.
Better handling and braking. Using carbon fiber wheel rim , because the elastic modulus of carbon fiber can reach 200 (gm^-200), the higher the elastic rate, the smaller the elastic deformation after stress. Similar to latex mattress, its comfort is better and its handling is great. After replacing the lightweight carbon fiber wheel hub, the suspension response speed of the car has been significantly improved. The faster and easier the acceleration, the better the braking performance.
