Information

Industry experts predict that in 2020, the use of plastic for each car will reach 350 kg from 200 kg in 2014. At the same time, carbon fiber will also show a threefold increase in the automotive manufacturing market. It is expected that by 2030, the carbon fiber use in the automotive industry will increase to 9,800 tons, compared with 3,400 tons in 2013.

  Automobiles have led the rapid growth of the chemical industry. In the next 17 years, the output of automobiles will double. According to the HIS Automotive Information Survey, the total number of automobiles in 2003 was 56.9 million, and this number will reach 104.1 million, and most of this growth will be driven by the fast-growing Chinese market.

  Judging from the actual situation, auto manufacturers began to adopt new materials in order to reduce the weight of cars and meet the emission standards set by the government. For example, the US Company ’s Average Fuel Economy Standard ( CA FE) mandates car manufacturers to reduce fuel consumption. European car road loads and greenhouse gas emissions must be reduced by 30%. This series of policies requires cars to use more advanced engines and variable speeds. Box and hybrid technology, in which the use of carbon fiber and polymer and composite materials can reduce the weight of the car body by 25% -70%.

  Composite materials have not yet accounted for "half of the country"

  In most cases, mainstream auto manufacturers will use traditional metal processing methods to reduce weight and produce cost-effective to improve competitiveness. Under the premise of ensuring a safe supply chain and cost-effectiveness, manufacturers will make bolder adjustments-using composite materials.

  Plastics have entered the automotive industry for some time. For example, polycarbonate glass replaces ordinary glass. Almost every car driving on the road has a P headlight and PC / PMMA taillight. The next goal of the PC is the car window, however, cost issues and regulatory issues limit the development of this material.

  The use of PC materials for car windows will bring more innovations. For example, the components can be integrated in the glass, and the windows / lights / barriers are combined to make a change in the overall style and price of the car. Maybe this will be a revolutionary Innovation.

  Some automotive manufacturers have adopted plastic or composite materials for automotive glass and interiors. They are currently seeking to change the road of automotive exteriors and try to use these materials in body panels to bring more subtle development.

  What kind of material is still being explored

  Carbon fiber has always been used to manufacture the most high-end racing cars, that is, using carbon fiber to make body panels, including A-class exterior wall panels, door panels, instrument panels and hoods, to reduce the car's own weight, even if this high cost of carbon fiber hinders its development market.

  Regarding cost, the chemical industry has given a definite answer-a mixture of foam, plastic and fiber composite materials, using standard extruded plastic and glass fibers sandwiched in the foam structure. The material can greatly reduce the weight on the original basis, while maintaining structural integrity. Bayer MaterialScience has exhibited this material at the 2013K exhibition. After using carbon fiber and polymer and composite materials, the weight can be reduced by 25% -70%, and it is within the price range acceptable to the manufacturer.

  BASF has become a leader in the lightweight revolution. At present, it has proposed a development solution for impregnating resin fibers, and deeply optimized the lightweight structure in the production of molds and plastics. This material has been used in everyday vehicles. For example, this solution can be used in mass-produced vehicles, but so far the technology only supports the replacement of auto parts. Experts predict that by 2020, these materials will bring a conceptual breakthrough and a new design storm in the automotive industry.

  Supply chain risk becomes an obstacle

  Although the prospects for new materials in the automotive industry are bright, there are significant potential risks in the supply chain. Composite materials and advanced plastics manufacturers need to invest huge expenses and supply bases worldwide. In addition, the reliability and reproducibility of the products are crucial. Although the profits are considerable, crude oil and raw materials can directly affect the manufacturing. cost.

  The production of raw materials with a small supply base can also be easily disturbed. For example, in 2011 the Evonik Industrial Group ’s polyamide factory fire and explosion caused the worldwide supply of polyamide raw materials to stop. This material is widely used in the automotive industry. It took nearly two years for Evonik to regain the market.
