The alloy is applied to the energy absorber of pedestrian protection, and the long glass fiber reinforced polypropylene is applied to the instrument panel and inner door module to make its self-weight less than

Automotive engineering plastics will replace more metal parts

The above. In addition to the British land rover, lamborghini, Mercedes

, BMW
i.
Series and many other models widely use more advanced automotive engineering plastics. Some experts even predict that the innovative application of new materials in the future may subvert the traditional automobile.
With smog, energy conservation and stricter fuel consumption regulations, Chinese automakers are sparing no effort to develop lightweight technologies for their vehicles. As we all know, the lightweight of automobile is mainly reflected in the optimization design of automobile, alloy material and non-metallic material application, which in turn is the lightweight weight reduction of automobile

. Zheng kai told reporters, engineering plastics and other non-metallic materials of the "weight reduction" effect is obvious, its main role in the car is to make the car lightweight. At present, more and more automobile parts begin to use engineering plastics instead of metal parts.
The application of automotive engineering plastics is increasing year by year

Gao song, a material engineering engineer at beiqi foton engineering research institute, said in an interview on Sunday.
Zhi-guo qian, chief engineer of Beijing institute of chemical industry research and development center, with plastic instead of metal parts, can not only reduce vehicle weight, reduce fuel consumption and emissions, can also increase the power, comfort and safety of cars, so it is widely used in automotive power and chassis systems, both inside and outside decoration, automobile electronic components.
Gao song introduction, polyamide

Plastic body coverings are ideal for use in heavily polluted areas

Steel parts are easy to rust and corrode the metal if the paint surface is damaged or the anticorrosion is not done well in advance, but automotive plastics are highly corrosive. The corrosion resistance of plastics to acid, alkali and salt is greater than that of steel plate. In addition, the cost of replacing metal parts with plastic parts can be reduced

Domestic research on automotive engineering plastics should be accelerated
Engineering plastics have many advantages and are valued and widely used by European and American automobile enterprises. It is reported that in developed countries, the amount of plastic per car from the last century

And high-performance engineering plastics, etc., while domestic brands of cars in the application of plastic composites

Relatively few. This also reflects our vehicle lightweight technology level gap.
Zheng kai believes that engineering plastics should be more widely used in automobiles, but there is not enough attention paid to the application of automotive engineering plastics in China.
Gao said every application of plastics in automobiles involves solving problems in structural design, manufacturing process and equipment, material selection and modification. In addition, the surface or coating, connection, test evaluation and other problems must be solved. In her opinion, the whole vehicle enterprises should, according to the needs of independent development, require the plastic parts suppliers, material suppliers and the whole vehicle enterprises to join hands and conduct research on the application technology of parts according to the needs of the development of new models in the future. Basf officials told the reporters: "to make the car lighter and more energy efficient, basf automotive plastic is widely used in automotive interior and exterior trim, power transmission and chassis, plastic hub and other parts, some parts can replace aluminum alloy materials, its weight reduction effect is obvious.
Engineering plastics began to replace some aluminum alloy parts
to
2020
In 2018, the average amount of plastic used in cars will likely reach 50 percent

The above. With the wide use of new energy vehicles, the cost of aluminum alloy and magnesium alloy is too high, and most of them are imported. In the future, the roof, door, seat parts, wheel hubs, and peripheral structural parts of the car, and even the car body, may be converted to engineering plastics. In fact, some foreign high-end car doors and other parts have begun to use engineering plastics.

The front end bracket of the golf is made of basf engineering plastics. The lack of metal supports greatly reduces component weight, assembly time and cost.
At present, the body made of plastic has been widely used in small batch production of cars or some high-end models, such as BMW
