Use of plastics in automobile will grow by 75% in 2020

Time:2017-02-17

Industry experts predict that in 2020, each car in the use of plastic will be from 200 kg to 350 kg in 2014. At the same time, the carbon fiber will also appear three times in the automotive market growth, predicts 2030, auto manufacturing carbon fiber usage will increase to 9800 tons, and in 2013 the figure was 3400 tons.


Car has led the rapid growth of the chemical industry, the next 17 years, auto output will double again, according to the survey of the ihs automotive information, a total of 2003 cars in 2003, to 2020, that figure will reach 104.1 million, which much of the growth will be driven by the rapid development of the Chinese market.


From the actual situation, automobile manufacturers to reduce vehicle weight, accord with the emission standards established by the government adopted new materials. The United States, for example, corporate average fuel economy standards (CAFE), force car makers to reduce fuel consumption, European vehicle road load and greenhouse gas emissions must be reduced by 30%, etc., this a series of policies required to adopt more advanced automotive engine, gearbox and hybrid technology, among them, the use of carbon fiber and polymer and composite materials can make the body weight decreased by 25% to 25%.


Composite materials are not accounted for "half"


In most cases, the mainstream of the traditional metal processing produce cost-effective method to reduce weight in order to improve the competitiveness, on the premise of safe, cost effective supply chain, manufacturing chamber of commerce to make bolder - using composite materials.

Plastic into auto industry already has a period of time, such as polycarbonate glass instead of the common glass, on the road car almost every station has a P headlights and PC/PMMA tail lights. PC next goal is to the window, however the cost problem and regulatory limits the development of the material.


Windows PC materials will lead to more innovation, such as the component can be integrated in the glass, Windows/light/column board collection together, make the integral style of the car and the price to make a change, maybe it is a revolutionary innovation.


Auto glass and trim some automakers use plastic or composite material, is seeking to change the car outside act the role of the road, trying to use these materials in automobile body panel, with the development of more sophisticated.


What material is still in groping


Carbon fiber has been used in the manufacture of the top racing, that is, using carbon fiber body panels, including grade A cladding, door plank, the dashboard and hood, to reduce automobile weight, even if such high costs of carbon fiber, hindered the development of the market.


Just cost problem, the chemical industry has been given a definite answer, foam, plastic and fiber composite material mixture, using standard extrusion plastic and glass fiber in the bubble structure. The material can be greatly reduced on the basis of original weight, while maintaining the integrity of the structure. Bayer materials science and technology in the exhibition of 2013 k on the material, the use of carbon fiber and polymer and composite materials after weight can reduce 25% to 70%, and the manufacturers can accept price range.


Basf has become a leader of lightweight revolution, has proposed the impregnating resin fiber development solution, and further optimize the structure of mould and plastic in the production of lightweight. This material has been used in the daily life in the vehicle. For example, this solution can be used in mass production of cars, but now only support the technology shift of auto parts. Experts predict that by 2020, these materials will bring in the automobile industry concept breakthroughs and new design storm.


Supply chain risk become obstacles


While the new material in the auto industry a bright future, but there is a big potential supply chain risk. Composite materials and the advanced plastic manufacturers need to invest huge costs and in operation worldwide supply base, in addition, the reliability and reproducibility of the products is crucial, although profitable, but the crude oil and raw materials can directly influence the manufacturing cost.


With a small supply base of raw materials to produce will be very easy to interference, such as evonik industries group of polyamide 2011 factory fire explosion, caused the world within the scope of polyamide stop supply raw materials, the material using the auto industry in a big range, evonik took nearly two years to regain the market.
