Advantages of carbon fiber car accessories
1. Drive shaft application. The stress situation of car transmission shaft is relatively complex. If we want to accept a large torque, we should fully consider the characteristics of carbon fiber composite material, such as anisotropy, high specific strength and relatively low specific modulus. Then, carbon fiber composite material transmission shaft can replace metal products to meet the application requirements. The carbon fiber transmission shaft can not only reduce the weight by 60%, but also has better fatigue resistance and durability.
2. The use of body and chassis. Because carbon fiber itself has enough strength and stiffness, it is the main structural parts of car body and chassis. By using this data, the weight of the car body and chassis can be reduced by 40% - 60%, which is equivalent to one third to one sixth of the weight of the steel structure. Now many racing car bodies and some modified car bodies use this kind of information.
3. The application of brake pads and the environmental protection and wear-resistant characteristics of carbon fiber car accessories are very suitable for brake pads. However, the price of this kind of products is relatively high, and they are generally used in high-end brand cars. The general brake disc will become red due to absorbing a lot of heat energy, and the carbon fiber brake disc can accept the high temperature of 2500 ℃, and has excellent braking stability, which greatly increases the driving safety.
The purpose of using carbon fiber car parts and carbon fiber motorcycle parts is to realize the lightweight of cars and motorcycles, and also to meet the rigid demand of cars and motorcycles. This can not only achieve the effect of energy saving and emission reduction, but also meet the fuel saving demand of car owners. Carbon fiber information is the mainstream information of cars and motorcycles in the future, and it is believed that it will be used more in the near future.
Now, the manufacturers of carbon fiber composite materials often use carbon fiber composite materials as raw materials for cutting. This method leads to an even utilization rate of only 50%, which means that nearly half of the valuable carbon fiber composite materials are wasted. In the development of Schuler and others, carbon fiber data can be used thoroughly without too much abandoned data. With the addition of output value, the production cost of original parts is reduced by more than half, and the production time is shortened by 30% to 40%.
The first step of the process is to use robot to spray short glass fiber foundation structure; the second step is to calculate the tensile strength of each part through the announced algorithm. Based on this data, another robot uses the process technology of Siemens and broetje to cover up the prepreg of carbon fiber tow, and uses apodium's 3D measurement system for optical control; the third process is to inject resin into the composite fiberboard. The resin is hardened under high pressure under the hydraulic press, and the forming of parts is completed. In this process, frimo's die technology is also used. According to the required wall thickness, the press can directly affect the deflection of the die. In this way, qualified parts can be produced from the beginning, and the scrap rate can be reduced to zero.
