美国肯塔基大学的研究小组最近尝试在一些大桥上粘贴一层薄薄的碳纤维板,使桥更加坚固。美国有30%以上的桥梁已经不符合要求,必须采用高强度的材料加固才能继续使用。这项尝试将为整修桥梁打下了基础。某些桥的梁柱在建造时使用了足够的钢筋水泥,现在工人们使用环氧胶水把薄薄的碳纤维板粘贴在跨梁上,然后再刷上一层环氧胶水用来加固。据估计,施工后的桥梁寿命可达50年左右。原本这项技术用于加固飞机的机身,如今却开始应用于桥梁的整修。它的好处是材料非常轻薄灵活,
A team from the University of Kentucky in the United States recently attempted to stick a thin layer of carbon fiber on some bridges to make the bridge stronger. More than 30% of bridges in the United States have failed to meet the requirements and must be reinforced with high-strength materials to continue their use. This attempt will lay the foundation for the renovation of the bridge. Beams and columns of some bridges were constructed with enough steel and cement. Workers now use epoxy glue to attach thin carbon fiber sheets to the beams, and then apply a layer of epoxy glue to reinforce it. It is estimated that the life span of the bridge after construction can reach about 50 years. The original technology used to reinforce the fuselage of the aircraft, but now it has begun to apply to the renovation of the bridge. Its advantage is the material is very thin and flexible,
