The advantages of carbon fiber composite materials in auto parts

Carbon fiber composite material with high strength, high modulus, flexible molding process, high temperature, low thermal expansion coefficient, light weight effect is obvious, used in aerospace, sports equipment, automotive high-speed rail, medical equipment and other fields, especially In the body structure, the lightweight effect is obvious. Xiaobian to talk about the following carbon fiber composite materials used in the automotive parts on the edge.

1) density is small, only 1.7g / cm ^ 3, is a quarter of steel to meet the requirements of lightweight vehicles, so as to achieve energy-saving emission reduction, reduce environmental pollution.
 

2) high strength, the tensile strength is several times as much steel, impact resistance, and for automotive body, due to the role of shock absorption, improve the safety of the car.
 

3) plasticity is better, according to the need to make a variety of complex parts, but also can be zero for the whole, access to the overall structure of the whole. Take the seat as an example, if it is iron, need to weld 50-60 parts, and carbon fiber composite material only a few components can be, greatly improve the production efficiency.

From the realization of the effect of lightweight, in the body parts of the use of carbon fiber reinforced materials, at least can reduce the quality of 20% to 30% or more. According to the study, the vehicle can reduce energy consumption by 6% for every 10% reduction in fuel consumption, which is conducive to energy conservation and reduce emissions. Costs, in less than 20,000 batches per year, due to the need to save expensive metal stamping, welding production equipment and mold investment, the use of composite materials, the overall cost of metal body than the metal body nearly 800 US dollars, according to an annual output of 2 Million calculations, saving $ 16 million per year. Therefore, the carbon fiber reinforced materials in the future development of environmentally friendly models, with strong competitiveness and good social benefits.
 

At present, carbon fiber composite materials are mainly used in small batch models, limousines and Fl car body parts, engine parts, transmission systems, chassis systems and other parts. Such as Ferrari F430 equipped with brake discs, Mazda RX-8 drive shaft, Toyota 1 / X hybrid car body skeleton. Located in Jiangsu, Wuxi VIA New Materials Technology Co., Ltd. strong technical force, and has a number of car manufacturers to cooperate for its production of rear-view mirror shell, vehicle power battery box, energy box and other carbon fiber auto parts, in the new material research and development And the application of the road has made remarkable achievements.
