摘要
本文针对单一纤维的FRP筋延性较差的缺点,开展了碳/玻混杂纤维复合材料筋生产工艺、受力性能的试验研究。结果表明:在拉伸试验中混杂纤维复合材料筋具有类似于普通钢筋的"屈服台阶",并对其基本物理力学性能的理论值与试验值进行了比较,结果吻合较好。为HFRP筋的工程应用提供了依据。
In this paper, aimed at the disadvantage of low ductility of simplex FRP bars, experimental research on the process and mechanical properties of carbon/glass HFRP bars are carried out. The results from tension test indicate that CG--FRP bars exhibit ＂yielding plateau＂ similar as steel bars, a comparison between theoretically and experimentally basic mechanical properties of CG-- FRP bars was investigated with coincidence results, which provide an evidence for the application of CG--FRP bars in the civil engineering.
