How to make carbon fiber materials for automobile
June 08, 2021
Maybe the process is like this, just the difference between manual and mechanical, because the fiber material is a kind of fiber through this adhesive to stick the fine fibers together. The strength and other properties of materials are affected by the quality and maturity of the process, and the quality of the fiber has a greater impact on the material. Generally speaking, the strength of fiber material in one dimension is very high. There is a video of a carbon fiber mountain bike made by a foreign Cowman himself, which is also made by sticking the filament on the mold in this way. Because carbon fiber composite has better designability than metal, it is easier to carry out the platform, modularization and integration of body development. Compared with the traditional carbody structure, the hybrid structure of carbon fiber carbody and metal platform can achieve modularization and integration, greatly reduce the types of parts, reduce the investment of mold and shorten the development cycle.
Generally, molding, vacuum introduction, hot pressing groove and other methods are used to make parts. Outstanding advantages of carbon fiber in automobile manufacturing industry: 1. After carbon fiber lightweight is applied to automobile, the most obvious benefit to automobile manufacturing is the lightweight of automobile. The most direct effect is energy saving, acceleration and improvement of braking performance. Overall, the vehicle weight is reduced by 10%, fuel consumption is reduced by 6% ~ 8%, emission is reduced by 5 ~ 6%, acceleration performance is improved by 8-10%, and braking distance is shortened by 2-7 M; The lightweight body can make the center of gravity of the whole vehicle move down, improve the vehicle handling stability, and make the vehicle driving safer and more stable. Carbon fiber composite has excellent energy absorption capacity, which is 6-7 times of steel and 3-4 times of aluminum, so as to further ensure the safety of automobile; 3. Carbon fiber composite has high shock absorption performance. Light alloy needs 9 seconds to stop vibration, while carbon fiber composite can stop vibration in 2 seconds. Therefore, the application of carbon fiber composite in automobile has the same contribution to the improvement of vehicle NVH (noise, vibration and acoustic roughness), which will greatly improve the comfort of automobile driving.
