&Nbsp Of High-Tech Fiber And Composite Materials Can Not Be Further Understood.

China should strengthen high-tech fiber and

At the Shanghai motor show this year, the CAS advanced technology research institute pioneered a carbon fiber electric vehicle that was really on the bright side, and many visitors stopped to wait and see.

Premier Wen Jiabao, who has gone to visit, particularly encouraged the Chinese Academy of Sciences to dare to break through, be good at innovation, and achieve breakthroughs in the field of new energy vehicle development and its industrialization.

This concept is small, but it is a small car at the QQ level, but it is the small car that has an extraordinary skill.

The car, which is developed independently from the drive train to the overall frame, is driven by pure electric drive. The maximum speed can reach 100 km / h, which can run continuously for more than 100 km.

What is more noticeable than the electric drive is its high rigidity body.

The car abandoned the traditional steel structure and made of carbon fiber material. The amount of carbon fiber reached 21 kilograms. With other lightweight materials, the amount of composite material in the vehicle reached 31.36 kilograms, which was more than 60 kilograms lighter than that of steel. The ultra lightweight body made the vehicle energy consumption decrease.

What is worth mentioning is the carbon fiber composite used in the body.

While the weight of the vehicle is greatly reduced, the impact resistance of the material is much higher than that of steel, especially the steering wheel made of carbon fiber. The mechanical strength and impact resistance of the steering wheel are increased by 35% and 20% respectively.

The strength of the vehicle is also 20% to 30% stronger than that of an ordinary material vehicle.

According to the head of the advanced technology research institute of the Chinese Academy of Sciences, although the car has been developed for several months, it has exhibited itself in the major exhibitions such as the industrial fair and the high tech fair.

It is understood that although the car is only a laboratory product, its market reaction has exceeded the expectations of R & D personnel.

On display several times, people feel the strong market demand of products.

During the exhibition, the CAS exhibitors continuously received the order contract.

However, when we turn our attention to the developed countries such as Europe, America and Japan, we cannot help but sigh the huge gap.

At present, the developed countries have been ahead of us in the understanding and successful development of the production of carbon fiber composite materials for automobiles. They have also taken a big step in the application of new materials for carbon fiber. They have also realized that the promotion of low carbonization of vehicles and the promotion of green production of vehicle materials will surely lead to a revolutionary change in the automotive industry.

At present, Germany and Japan have been considering the realization of mass production of carbon fiber vehicles in the next two or three years.

The German carbon fiber company established a joint venture with BMW in 2009. It invested 100 million US dollars to build a carbon fiber factory in the United States. The purpose is to make carbon fiber composite materials widely used in the manufacture of BMW cars, so as to make the BMW car leading to lightening.

Coincidentally, the Japanese Dongli company invested $24 million 300 thousand in 2008 to build an automobile center, and made the carbon fiber composite material for the first time in the manufacture of Mercedes Benz, reducing the weight of the vehicle by more than 10%.

In recent years, the world's major automobile manufacturers have joined hands with CFRP manufacturers to accelerate the application of CFRP in the automotive industry, so as to achieve vehicle weight reduction and energy saving.

However, there is a big gap between China and the developed countries in the field of development and application. The main reason is that the ideological understanding lagged far behind the developed countries, and there is a lack of integrity and foresight in industrial planning and development.

According to the insiders, during the "12th Five-Year" period, China will vigorously develop the new energy industry and focus on the development of energy saving.

The electric vehicle developed by the Academy of advanced science and technology of the Chinese Academy of Sciences can fill the gap of our country, though it has a long way to go from mass production to the project, but after all, it is our own "original works" with complete independent intellectual property rights.

If the relevant departments of the state are fully aware of the importance of high-tech fiber and composite materials for new energy vehicles and new energy industries, and take effective policy guidance, China hopes to shorten its gap with developed countries through its own strength.

China's automobile production and marketing in 2010 exceeded 1 million 800 thousand vehicles, ranking first in the world.

The demand for weight reduction and the requirements for safety, comfort, energy conservation and environmental protection will inevitably create strong demand for carbon fiber and composite materials.

The use of Airbus A380 composite material has reached 85%. The large number of composite materials used by automobiles is lagging behind the field of large aircraft manufacturing. But this is the general trend. We can not afford to lose sight of the opportunity.
