In the automotive industry, the original motivation for plastics to replace glass for window manufacturing was to reduce fuel consumption by reducing vehicle body weight, but today, other factors are becoming more important than this original need. Improvements in the car's drag coefficient make the effect of reducing the weight of the windows less noticeable on the car. Studies have shown that "the effect of reducing the weight of each vehicle by 30 to 40 kilograms through the use of plastic is not as good as the effect of lowering the center of gravity of the whole vehicle and optimizing the load distribution of the front and rear axles." This provides the best motivation for the search for the car. Learn to express new directions and play a substantial role in improving driving pleasure while improving safety.
In addition, the plasticity of plastic is unmatched by glass. Some geometric shapes with beautiful shapes are almost impossible for glass to achieve continuous large-scale production in recent years. And due to some characteristics of plastic itself, although the hardness is low, it is not as good as glass in terms of wear resistance. However, plastic can be designed into a more rigid geometric shape, and the hardness can be improved by surface coating, so it is worse than glass in terms of safety. . In physical collisions, plastic structures can reduce the number of fragments due to their better toughness. Maintaining the integrity of the surviving enclosure as much as possible is also important for safety in the event of an accident.
Of course, the advantages of light weight have not been obscured by the moon because of the above advantages. In the follow-up steering technology, the weight of glass components is the biggest obstacle to testing the life of the steering mechanism and affecting the flexibility of structural design. The huge volume and weight of the reflective light distribution, especially the vibration inertia during operation, make the follow-up mechanical structure face difficulties. After high-power LED lighting and plastic parts, there is no need for the reflector cup and the excellent plasticity of the plastic. etc. can be integrated into a smaller structure, making the follow-up steering light and flexible. In addition, in the 1-liter economy cars launched by some international companies, the degree of plasticization is still the most important factor in reducing weight and reducing the number of assemblies.
