Die toepassing van koolstofvesel in hoëspoed spoor, metro busse en nuwe energie voertuie

        The subway bus is a brand-new means of transportation, and the way of riding and running is the same as that of the subway. The basic features of subway buses that have appeared in the domestic market in recent years are one-step boarding, fully flat floors, and large passages. The advantages are convenience, high speed, comfort and safety. This kind of urban public transport pursues low energy consumption, greenness and environmental protection. Carbon fiber composite materials are used in large quantities in the body materials, which can reduce the weight of the car body. A carbon fiber composite subway bus was recently released in China. 100% of the domestic carbon fiber composite material is used. The weight reduction of the whole vehicle can reach 2,600 to 3,000 kilograms, and the ride efficiency is increased by at least 50%. The standing area of the same number of seats has been increased by more than 60%, which greatly reduces energy consumption, realizes economical and efficient operation, and achieves the goal of energy saving and emission reduction, which contributes to the green and low-carbon development of public transportation.

       Industry experts predict that if carbon fiber composite materials are more affordable in terms of raw material prices and process costs, the application ratio of carbon fiber composite materials in high-speed rail may reach about 30% in the future. Now carbon fiber composite materials can meet the basic requirements of rail vehicle interior trims and non-main load-bearing structural parts, covering strength and stiffness, weight reduction, etc. For most cabin components, such as toilets and lavatories, body panels, seats, water tanks, etc., carbon fiber composite materials not only reduce weight, but also have the advantages of fatigue resistance and corrosion resistance.

       For traditional fuel vehicles, every 10% reduction in the weight of the car body can increase the fuel efficiencyof the car by six to eight percent. The experimental data shows that for every 100 kilograms in the weight of the car,the fuel consumption of 0.3L to 0.6 can be saved by driving 100 kilometers, and the carbon dioxide emission will alsobe reduced by about one kilogram.For new energy vehicles, lightweighting is more far-reaching, because now the soft underbelly of new energy vehicles is battery life. Using carbon fiber composite materials instead of traditional metal materials is a very effective way to reduce the weight of new energy vehicles. Because carbon fiber composite materials are not only light in weight, high in strength, but also have good energy absorption effect. When the car is hit, the carbon fiber composite material can absorb the huge impact force caused by the collision, play a good buffer and shock absorption effect, reduce the car debris caused by the impact, and effectively improve the safety of the car.
