摘要
碳纤维增强复合材料(Carbon Fiber Reinforced Polymer,简称CFRP)是由碳纤维材料与基体材料按一定比例混合并经过一定的工艺复合形成的高性能新型材料,因其具有高强、轻质、耐腐蚀以及施工方便快捷等优点,被广泛用于结构加强及加固领域,国内外利用CFRP片材加固混凝土梁经历了一个漫长的过程。该文通过对CFRP片材预应力加固混凝土梁发展历程的总结,阐述各种CFRP片材预应力加固混凝土梁方法及其优缺点,为需要利用CFRP片材预应力加固混凝土梁的设计者提供参考。
Carbon Fiber Reinforced Polymer（CFRP）, made from mixing carbon fiber material and matrix material with a certain ratio,is proved a high-performance composite material. It is widely adopted in structural strengthening and reinforcement for its advantages of high strength, light weight,good corrosion resistance and fast construction. But the CFRP reinforced concrete beam has gone through a long process at home and abroad. Through summarizing the development of the CFRP pre-stressed reinforced concrete beam,the methods and the advantages and disadvantages of various pre-stressed reinforced concrete beams are elaborated for reference.
