In addition to being used as a thermal insulation material in traditional use, carbon fiber is often used as a reinforcing material to be added to resin, metal, ceramics, concrete and other materials to form composite materials. Carbon fiber has become the most important reinforcing material for advanced composite materials. Because carbon fiber composite materials have the characteristics of lightness and strength, lightness and rigidity, high temperature resistance, corrosion resistance, fatigue resistance, good structural and dimensional stability, good designability, and large-area integral molding, they have been used in aerospace, defense, military, and civil industries. The various fields are widely used.
In recent years, carbon fiber, a high-strength and lightweight material, has been introduced by many automakers into their high-performance models, such as carbon fiber body covers, carbon fiber tails, and so on.
Considering the cost of carbon fiber itself and other input costs, few manufacturers have been willing to apply carbon fiber to civilian running shoes-wheels.
Now let me introduce you to the advantages of carbon fiber wheels
Carbon fiber is a new type of high-strength, high-modulus fiber with a carbon content of more than 95%. The weight is lighter than metal aluminum, but the strength is higher than steel, and it has the characteristics of corrosion resistance and high modulus. It is an important material with excellent mechanical properties in national defense, military and civilian applications. The carbon fiber wheel adopts a two-piece design, the rim is made of carbon fiber material, and the spokes are made of forged lightweight alloy. With forged rivets, the weight is about 40% lower than that of a general wheel of the same size.
2. Higher strength
The density of carbon fiber is 1/2 of aluminum alloy, but its strength is 8 times that of aluminum alloy. It is known as the king of black gold materials. Carbon fiber technology can not only make the body lightweight, but also strengthen the body's strength. The weight of a car made of carbon fiber is only 20% to 30% of that of an ordinary steel car, but the hardness is more than 10 times.
3. More energy saving
According to the research of relevant experts, the efficiency of reducing the unsprung mass of 1kg by using carbon fiber wheels can be equivalent to reducing the unsprung mass of 10kg. And every 10% reduction in vehicle weight can reduce fuel consumption by 6% to 8%, and reduce emissions by 5% to 6%. Under the same fuel consumption, a car can drive 50 kilometers per hour, which helps to improve The acceleration and braking performance of the car.
4. More durable performance
The constituent elements of carbon fiber composite materials are stable, and their acid resistance and corrosion resistance exceed those of metals. It also means that the designer does not need to consider the performance degradation caused by corrosion during the use of the product, which also provides more possibilities for reducing the weight of the car and improving the performance.
5. Better override
Carbon fiber wheels have a good shock absorption effect, and have the characteristics of stronger handling and higher comfort. After replacing the lightweight carbon fiber wheels, the suspension response speed of the car has been significantly improved due to the reduced unsprung mass, and acceleration is faster and easier.
