Industry experts predict that by 2020, every car

plastic

Its use will rise from 200kg in 2014 to 350kg. Carbon fibre is also expected to triple in the car manufacturing market, to 9,800 tonnes by 2030, up from 3,400 tonnes in 2013.

In the next 17 years, the output of automobiles will double again. According to HIS automobile information survey, the total number of automobiles in 2003 was 56.9 million, and the number will reach 104.1 million by 2020, and most of the growth will be driven by the rapidly developing Chinese market.

In practice, automakers are using new materials to reduce vehicle weight and meet government emissions standards. 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 70%.

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

In most cases, mainstream automobile manufacturers will adopt traditional metal processing methods to reduce weight and generate high cost performance to improve competitiveness. On the premise of ensuring safety supply chain and cost-effectiveness, manufacturers will make bolder adjustment -- using composite materials.

Plastics have been in the automotive industry for some time, such as polycarbonate glass replacing regular glass, and nearly every car on the road has a P headlight and a PC/PMMA taillights. The PC's next target is Windows, but cost and regulatory issues have limited the development of the material.

Windows made of PC materials will bring more innovations, such as components can be integrated in glass, Windows/light/panels together, making the overall style and price of the car change, which may be a revolutionary innovation.

Some car manufacturers already use plastic or composite materials for car glass and interiors, and are now looking to change the way car exteriors are done by finding ways to use these materials in body panels for more subtle developments.

The materials are still being explored

Carbon fiber has been used to make high-end racing cars, which use carbon fiber to make body panels, including a-class exterior panels, doors, dashboards and hoods, to reduce the car's weight, even as its high cost has hindered its market development.

The chemical industry has come up with a definitive answer to the question of cost -- a mixture of foam, plastic and fiber composites, sandwiched in a foam structure using standard extruded plastics and fiberglass. The material can be greatly reduced in weight on the original basis, while maintaining the integrity of the structure. Bayer materials technologies presented the material at the 2013K show, which USES carbon fiber and polymers and composites to reduce weight by 25 to 70 percent and is within the manufacturer's price range.

Basf has emerged as a leader in the lightweight revolution, and has developed solutions for impregnating resin fibers and further optimizing lightweight structures in mold and plastics production. The 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 replacement of car parts. Experts predict that by 2020, these materials will bring a storm of conceptual breakthroughs and completely new designs in the automotive industry.

Supply chain risk becomes an obstacle

While the prospects for new materials in the automotive industry are bright, there are significant potential risks in the supply chain. Composite and advanced plastics manufacturers operate with significant costs and a worldwide supply base, and product reliability and reproducibility are critical, although profitable, as crude oil and raw materials can directly affect manufacturing costs.

For example, in 2011, a fire and explosion occurred in the polyamide plant of evonik industrial group, which caused the suspension of the supply of polyamide raw materials worldwide. This material was widely used in the automobile industry, and it took evonik nearly two years to regain the market.
