Plastic helps to reduce the amount of light fuel oil consumption
Plastic helps to reduce the amount of light fuel oil consumption
Lightweight materials such as plastic than conventional high speed steel (HSS) and aluminum in strength, impact resistance, easy forming, heat preservation, beautiful sex and vibration and noise control has a better performance, at the same time can reduce the body weight, be the first choice of the automotive lightweight alternatives.
"Light and luxurious" became the slogan of this session at the north American international auto show in Detroit. For every 10 percent reduction in the weight of a car, fuel consumption decreases by 6 percent to 8 percent, while reducing emissions by 5 to 6 percent. Therefore, all major automobile manufacturers compete for the light quantification to improve fuel efficiency and contribute to the sustainable development of the industry. As the green tide sweeps around the world, different environmental policies have been launched, such as the CAFE standard that the United States will implement in 2025. The eu is considering stricter emissions standards for carbon dioxide by 2020; China on October 1, 2013, tightening below 1.6 liters and for energy conservation and environmental protection car promotion policy to implement higher emission standards and so on, which have encouraged industry towards the direction of lightweight, energy saving and environmental protection.
Recently, the American chemistry council (ACC) plastic branch of new automotive plastic planning blueprint, according to the need to display more the ability of plastics and polymer composites, to expand the use of these materials in automotive applications.
The group released its first blueprints for car use in 2001, most recently in 2009. Latest version called "automotive plastics and polymer composites technology planning blueprint", aims to build a framework, enlarging the plastic penetration and polymer composites in the automotive industry, especially application focused on weight loss and achieve fuel efficiency standards.
According to the national highway traffic safety administration and the state environmental protection agency's corporate average fuel consumption (CAFE) standards, carmakers need up to 50 MPG by 2025 or more fuel efficient. The blueprint says automakers are increasingly considering using plastics as lightweight alternative materials for traditional materials. For example, carbon fiber reinforced composites are 50 percent lighter than conventional steel and 30 percent lighter than aluminum.
According to the American chemical industry association, plastic now makes up about 50% of the car's volume, and the total weight of the components is less than one percent of the weight of the car. On average, a car with more than twenty thousand pieces of different plastic parts, including such as interior parts, from inside the car seat base, instrument panel, so that the external body panels, such as bumper, windshield, headlights, recently the application of plastic has extended to the hood and components under the hood, underlines the importance of plastics in automobile industry. In addition, safety regulations also help the car's plasticization process, such as the country is considering installing a device that can absorb energy before the car bumpers system.
In order to improve the market competitive advantage, automobile manufacturers have developed and adopted lightweight design models to meet the requirements of customers for energy conservation, safety and comfort. In recent years, plastic production technology has been continuously improved, and new materials such as complex, modified plastic and reinforced plastics have emerged, consolidating the position of plastics in the automobile industry. Among them, BMW, Toyota, Volkswagen, Daimler and others have been the first to develop carbon fiber reinforced plastic, as a car shell. The Great Wall is made into a panoramic skylight with polycarbonate. Beiqi fukuda used glass fiber reinforced plastic to build parts of auto parts.
