The lightweight of automobile refers to reducing automobile as much as possible under the premise of ensureing the intensity and security performance of automobile
Kerb weight reduce fuel consumption to improve the dynamic property of automobile, reduce exhaust pollution.It is demonstrated experimentally that car mass drops
It is at half, fuel consumption can also reduce nearly half.Vehicle weight often mitigates 10%, and fuel efficiency can be improved 5%~7%；Vapour
Vehicle kerb weight often reduces 100 kilograms, and fuel consumption per hundred kilometers can reduce by 0.3~0.6 liter；Exhaust emissions can reduce by 8~11 grams.By
In environmental protection and energy-efficient needs, the lightweight of automobile has become the trend of world car development.Existing body of a motor car is most
It is made, thus had the disadvantage that by fiberglass and iron plate：First, it is light to automobile cannot to meet people for car body weight weight
The demand of quantization, while also exacerbating the consumption of the energy；Second, the prices of raw materials are expensive and complex manufacturing technology, mold are various
Etc. causing, the production cost is very high；Third, vehicle body energy-absorbing buffering ability is poor, impact strength and yield tensile strength up for
Improve；4th, glass fibre reinforced plastics body does not have deformation restorability usually all to be needed when vehicle body is collided and is deformed
It replaces or by external force reparation.
In view of the foregoing drawbacks, the generally use almag of domestic automobile lightweight at present replaces traditional fiberglass or iron plate
As the material of body of a motor car, the weight that body of a motor car considerably reduces body of a motor car is made using magnesium-aluminium alloy material, for
The consumption of energy consumption is reduced in vehicle traveling process, while also adding somewhat to the intensity and yield tensile strength of vehicle body.
But use magnesium alloy to make body of a motor car and also need numerous molds, it needs to carry out complicated process, production process is multiple
It is miscellaneous and not easy to operate.
Meanwhile not destroy former vehicle vehicle paint, enhancing former vehicle vehicle paint protective effect, exempting the expenses such as glaze-sealing film-coating, some vehicles
Main selection pastes macromolecule polymeric material film in bodywork surface, but vehicle body needs to paint again once being generated cut by scraping
When, it has to film is torn, waste is caused.
