Manufacturing process of carbon fiber car accessories and its advantages to car manufacturing
Carbon fiber car accessories are generally manufactured by molding, vacuum introduction, autoclave and other processes. What advantages can carbon fiber car accessories bring to car making? I'll give you an introduction today.
1. Improve the level of body development
Because carbon fiber composite has stronger plannability than metal, it is easier to channel, modularize and integrate the body development. In this way, the hybrid body structure of carbon fiber body and metal channel can achieve modularization and integration for the traditional car body structure, greatly reduce the types of parts, reduce tooling investment and shorten the development cycle.
2. Lightweight
After the application of carbon fiber in car, the remarkable benefit to car manufacturing is the lightweight of car, which directly affects the improvement of energy saving, acceleration and braking function. Generally speaking, the vehicle weight is reduced by 10%, the fuel consumption is reduced by 6% ~ 8%, the emission is reduced by 5 ~ 6%, the 0-100km / h acceleration is increased by 8 ~ 10%, and the braking distance is shortened by 2 ~ 7m.
3. Security
Lightweight body can make the center of gravity of the whole car move down, improve the operation stability of the car, the operation of the vehicle will be more safe and stable. Carbon fiber composite material has excellent energy absorption rate. The energy absorption ability is six to seven times that of steel and three to four times that of aluminum, which further ensures the safety of the car.
4. Reliability
Carbon fiber composites have higher fatigue strength. The fatigue strength of steel and aluminum is 30-50% of the tensile strength, while the fatigue strength of carbon fiber composites can reach 70-80%. Therefore, the fatigue reliability of carbon fiber composites used in cars is greatly improved.
5. Comfort
Carbon fiber composite has higher damping, light alloy needs 9 seconds to stop the sensation, carbon fiber composite can stop in 2 seconds, so the application of carbon fiber in cars, the improvement of vehicle NVH (noise, vibration and sound vibration roughness) is the same, will greatly enhance the comfort of cars.
