Carbon Fiber Instead Of Metal Becomes The New Favorite Of Luxury Cars

Decades ago, some experts prophesied. carbon fibre It will replace metals to make automobile structural parts. Now this prediction has become a reality. Carbon fiber reinforced polymer (CFRP) has attracted the attention of many luxury car manufacturers due to its small quality, high strength, high rigidity and good corrosion resistance.

Carbon fiber reinforced polymer matrix Compound material It has sufficient strength and stiffness, which is suitable for making the lightest material of main structural parts such as car body and chassis. It is predicted that the application of CFRP can reduce the weight of vehicle body and chassis by 40%~60%, which is equivalent to 1/3~1/6 of steel structure weight.

The weight reduction effect of carbon fiber reinforced polymer (CFRP) has been studied in the British material system laboratory. The results show that the carbon fiber reinforced polymer material is 172kg heavy, while the steel body weight is 368kg, and the weight loss is about 50%. However, due to the high cost of carbon fiber manufacturing, the application of carbon fiber reinforced composites in automobiles is limited. It has been applied only to some F1 racing cars, super sports cars and small batch vehicles, such as cornssag, Lexus LFA, and Japan's Refitting Factory. At present, BMW M3, which is equipped with carbon fiber roof, is also officially released in China. The carbon fiber Limited Edition released by the same time is based on the roof of the car, which is equipped with carbon fiber front spoiler, tail wing, interior details and other components.

Carbon fiber is also environmentally friendly. Wear-resisting The feature is applied to the brake pad, but the products containing carbon fiber composite material are extremely expensive, so the brake disc is mainly used in the high-end cars at present.

Carbon fiber brake discs are widely used in racing cars, such as F1 racing cars. It can reduce the speed of the vehicle from 300km/h to 50km/h at the distance of 50m. At this point, the temperature of the brake disc will rise to more than 900 degrees, and the brake disc will turn red because it absorbs a lot of heat. Carbon fiber brake discs can withstand high temperatures at 2500 degrees Celsius and have excellent braking stability. {page_break}

Although carbon fiber brake discs have excellent performance in deceleration, it is not practical to use carbon fiber brake discs in mass production vehicles.

Because the performance of carbon fiber brake discs can reach the best when the temperature reaches above 800 C. That is to say, after several kilometers of driving, the vehicle's braking device can enter the best working condition, which is not suitable for most short distance vehicles. In addition, carbon fiber brake discs wear rapidly, and the manufacturing cost is very high.

Carbon fiber car seat heating pad is a breakthrough in the application of carbon fiber in the automotive industry. Carbon fiber heating element technology is becoming more and more popular in automobile matching. It will completely replace the traditional seat system. At present, almost all the high-end and luxurious cars in the world are equipped with this seat heating device, such as Mercedes Benz, BMW, Audi, Volkswagen, Honda, Nissan and so on.

Carbon fiber thermal load carbon fiber is a highly efficient thermal conductive material with a thermal efficiency of up to 96% and evenly distributed in the heating pad to ensure uniform heat in the heating area of the seat. release The carbon fiber line and the uniform temperature distribution ensure that the heating pad is used for a long time to keep the leather on the seat surface smooth and intact. No trace marks, no local discoloration. When the temperature exceeds the set interval, the power is cut off automatically, and the temperature can not be automatically adjusted when the temperature is required.

Carbon fiber has infrared wavelengths suitable for human absorption. It has a health promoting function and can reduce driving fatigue and comfort.
