Why hasn’t carbon fiber been fully covered on rail transit?

With the increasing application of carbon fiber composite materials, it is well known that carbon fiber composite materials have very high strength properties, and there are cases where carbon fiber products are used in many industries, where rail transit is relatively common. An industry that has received unanimous praise. VIA New Materials also cooperates with China Railway and CRRC. The actual products include high-speed rail locomotives, instrument tables, high-speed rail sidewalls, etc., but for the time being, no high-speed rail is made of carbon fiber. In fact, it is related to many aspects
An important reason why carbon fiber composite materials are applied to the Zhongdao transportation industry is that it has a great relationship with the overall lightness of the carbon fiber products produced by this material, which can greatly reduce the weight of rail transit vehicles. The research on vehicle lightweight is divided into two directions, one is lightweight design, and the other is the use of lightweight materials. At present, the lightweight design of aluminum alloys has reached the bottleneck, and further weight reduction will inevitably affect other properties
So far, carbon fiber composite materials have become a new choice for people.
Nowadays, the more popular high-speed trains, in order to ensure safety, the whole body is made of stainless steel, and other parts are mostly made of aluminum alloy, just to meet the performance of the prestige, but the weight of each model is still very high. It is heavy and requires more energy consumption. After the carbon fiber material products are applied to the high-speed rail, the self-weight of the vehicle will be lower. According to the law of energy conservation, F=MA, the mass star is lighter, allowing the train to move. The energy consumption is also lower, and the inertia of the vehicle is also lower, and the vehicle starts and stops more quickly, including the reduction of the weight, which will also reduce the wear of the axle and wheels, and the service life will be longer.
In addition to being light in quality, Naxuan fiber products have very high strength, which can have better performance advantages in the application of rail transit products, which greatly improves the safety of high-speed trains. And a series of performances have a good performance, so that carbon fiber products have a presence in rail transit.
The performance of the Pobyway material is good, but there are many reasons why the carbon fiber material is still not fully used in Gaojian. Nowadays, more parts are still the main component. This aspect is because the price of carbon fiber material is relatively expensive. In addition, the mechanical properties of carbon fiber materials are very high, but the performance in the actual verification of such a product has not been able to be analyzed in batches for actual combat applications.
Then, in rail transit, high-speed rail products often require vehicle inspection. Sometimes it is necessary to remove the car paint and then inspect the cracks. If carbon fiber materials are used for the entire maintenance, Zhou Yu cannot be determined. Maybe There are certain security risks
