玻纤无屈曲织物/乙烯酯复合材料-混凝土柱增强系统的抗压破坏研究

Research on the Failure of the Concrete Column Cylinders Reinforced with Glass Non-crimp Fabric-Vinyl Ester Composite Wraps

采用由玻璃长丝纤维无屈曲织物与乙烯酯组成的复合材料对混凝土柱进行包裹增强。探讨了纯混凝土柱、不同复合材料包裹层数及不同纤维取向的织物增强试样在抗压试验过程中的破坏过程及形式 ;外界预冲击作用和环境因素———水与热的侵蚀对该复合材料 -混凝土增强系统抗压破坏的影响。为进一步提高其抗压破坏能力 ,并进入实际应用提供研究依据。

In this research,the concrete column cylinders are reinforced through composite wrap manufactured from glass non crimp fabric and vinyl ester resin.The compressive failure of these cylinders is observed and analyzed.The effect of the number of composite wrap layers,the fiber orientations of non crimp fabrics,external impact and environment factors on the compressive failure are discussed.The result can be used as a reference for further research and practical application.
