Application of plastic new material in automobile field

Published:2015-07-03

New material technology and nanotechnology, biotechnology, information technology integration, the trend of intelligent function material structure and function integration, obviously, low-carbon, green, renewable cycle and environmental friendly properties of materials have attracted much attention. In the new field of electronic information, biomedicine, energy conservation, environmental protection and intelligent traffic will be just unfolding, the functional, lightweight, miniaturization, green new materials demand; in this case, new plastic materials in various fields to accelerate the promotion of green, low carbon environmental protection has become the development of the plastics industry trend.

"This is the first large-scale use of carbon fibers for mass production." A body frame structure and full use of carbon fiber reinforced plastics manufacturing BMW I3 has attracted a lot of people come to visit, frame roof, silver black except with a cool, high performance plastics can not only reduce weight, from environmental protection effect, can reduce fuel consumption and carbon dioxide emissions.

"The car seat is also made of plastic, replacing metal with composites, which weighs 20% less than traditional seats." Shen Jiahong of BASF China Ltd. told reporters.

Site experts, automotive lightweight mainly reflected in the automotive optimization design, alloy materials and non-metallic materials applications, which in turn for the automotive lightweight, weight loss of 10% to 15%, 30% to 40%, 45% to 55%.

In fact, attaches great importance to reduce the carbon footprint of the automobile manufacturing industry has become the consensus of the day before, the Ministry issued "automobile harmful substances and Recyclable utilization management requirements (Draft)", "green" means that the industry will further strengthen the development of the tone.

The "requirements" put forward, the automobile production enterprises as the main responsibility for pollution control, should actively carry out ecological design, the structure and function of reasonable design, selection of non-toxic or low toxicity and low environmental protection materials and parts easy dismantling, utilization and application of high resource utilization, environmental pollution is small, easy to use green manufacturing technology the recovery.

Plastic materials have a lower carbon footprint than glass and metals because of their lighter quality. China's engineering plastics industry association secretary general Zheng Kai said, engineering plastics and other non-metallic materials "weight reduction" effect is obvious, more and more automotive parts began to use engineering plastics instead of metal parts.

It is reported that the developed countries will use plastic cars as an important symbol to measure the level of design and manufacturing level of the car, each car plastic content from the last century, in 90s 100 ~ 130kg increased to 152kg in 2004 and 174kg in 2006, now the amount is 230kg, the largest amount of German cars, accounting for more than 15% of vehicle materials. Experts predict that by 2020, the average amount of plastic vehicles will probably reach more than 500kg/ vehicles, accounting for more than 1/3 of the vehicle materials.

Many experts also said that foreign brands now have large-scale use of plastic composite materials and high performance engineering plastics, while the domestic brand cars in plastic applications for composite materials (weight ratio) is relatively small. This also reflects the level of our vehicle lightweight technology to be improved.
