With the development of the automobile industry and the large-scale application of engineering plastics in automobiles, automobile bumpers, as an important safety device, are also on the road of innovation. At present, in addition to maintaining the original protection function of the front and rear bumpers of the car, it is also necessary to pursue the harmony and unity with the body shape, and pursue its own lightweight.
The benefits of plastic bumpers
From the safety point of view, the car bumper can play a buffering role in the event of a low-speed collision accident and protect the front and rear car bodies; from the appearance point of view, it is decorative and becomes an important part to decorate the appearance of the car; at the same time, the car bumper also has Certain aerodynamic effects. The advantages of plastic bumpers are:
Control manufacturing costs and reduce weight
It is undeniable that the original intention of using plastic materials for automobile bumpers is to save costs. Plastic bumpers not only save manufacturing costs, but are also relatively easy to produce. And after the cost of car manufacturing is controlled, the price of the final product in the hands of consumers will be more reasonable.
Modern automobile production has been modularized. In addition to the use of high-strength materials for the body, many components will be made of materials that are lightweight, corrosion-resistant, easy to process, easy to form, and easy to maintain and replace. It is reported that for every 100kg reduction in the weight of traditional fuel vehicles, the fuel consumption per 100 kilometers is reduced by 0.3-0.6L, and the CO2 emission is reduced by 5-8g.
In addition to the front and rear bumpers of the car, some exterior parts of the body, such as fenders, may also be made of lightweight materials such as plastics. Of course, some top sports cars will also use a lot of carbon fiber materials to replace metal materials on the body, the purpose is very simple: the body is lighter, the braking is faster and safer, and it is more fuel efficient.
