European and American countries have made significant progress in the material research and development of anti-collision systems for elevated bridges. The application of a series of new materials not only improves the performance of anti-collision systems, but also extends the service life of elevated bridges. This article will explore the progress of new materials for elevated collision prevention systems in Europe and America from the professional perspective of Chongqing Julei Machinery Equipment Co., Ltd., a well-known domestic shock absorber manufacturer.

1、 Carbon fiber reinforced materials: a perfect combination of lightweight and strength

Carbon fiber reinforced materials have been widely used in European and American elevated anti-collision systems due to their lightweight, high strength, corrosion resistance, fatigue resistance, and other characteristics. Compared to traditional steel, carbon fiber reinforced materials can significantly reduce the weight of collision prevention systems, alleviate the overall load of elevated bridges, while maintaining or even improving collision prevention effectiveness. Chongqing Julei Machinery Equipment Co., Ltd. is closely monitoring this trend and has attempted to introduce carbon fiber materials into some of its products to enhance their competitiveness.

2、 High damping rubber: absorbs impact and protects the structure

High damping rubber is another popular new material in European and American elevated anti-collision systems. It has good shock absorption and energy absorption performance, which can effectively absorb impact energy during vehicle impact and protect the elevated bridge structure from damage. The use of high damping rubber not only improves the safety of the collision avoidance system, but also reduces the noise and vibration caused by impact, improving the quality of life of surrounding residents.

3、 Self repairing concrete: intelligent response to crack challenges

Self repairing concrete is a major highlight of the new materials used in European and American elevated anti-collision systems. By adding special repair agents or microorganisms to concrete, once cracks appear, these repair agents or microorganisms can fill the cracks, thereby maintaining the integrity and durability of the concrete structure. The application of this innovative material significantly reduces the maintenance cost and difficulty of elevated bridges, and extends their service life.

4、 Application prospects and challenges

The widespread application of new materials in the anti-collision system of European and American elevated bridges marks a new level of anti-collision technology for elevated bridges. However, the application of these new materials also faces challenges in terms of cost, construction techniques, and other aspects. In the future, with the reduction of material costs and improvement of construction techniques, these new materials are expected to be promoted and applied in more fields.

5、 Conclusion

Chongqing Julei Machinery Equipment Co., Ltd., as a leader in the shock absorber industry, has always been committed to technological innovation and product upgrades. We will continue to monitor the progress of new materials for elevated collision prevention systems in Europe and America, and actively introduce and apply these new materials to provide customers with safer, more efficient, and reliable shock absorption products. At the same time, we also look forward to strengthening exchanges and cooperation with domestic and foreign peers to jointly promote the healthy development of the shock absorber industry.
