In the present study, tensile tests were carried out to investigate the tensile behaviors of textile reinforced mortar (TRM) composite specimens. The TRM specimens were composed of one layer of carbon fibers, as the reinforcement, and aluminum cement-based mortar, as the matrix. The primary parameter of the test specimens was the anchorage method, which was newly developed to improve the tensile behavior of the composite: spreading the ends of fiber filaments, reinforcing the ends of fiber filaments using glass fiber reinforced polymer tabs or steel rebars, and coating the ends of fiber filaments with aluminum oxide powder. From the test results, it was found that most TRM specimens using developed anchorage methods exhibited ductile behavior. Moreover, the use of the developed anchorage methods could increase the cracking strength and peak strength of the composite specimens up to 66.1 and 97.9%, respectively. The failure mode of the test specimens was governed by a partial rupture of carbon fibers, except for the BASE specimen and specimen reinforced with steel rebars. Finally, the tensile stress–strain relationship of TRM specimens was idealized as bilinear stress–strain response curves following the guidance specified in ACI 549.4R-13.

不同锚固方法表征的碳纤维纺织增强砂浆 (TRM) 的拉伸性能

在本研究中，进行了拉伸试验以研究织物增强砂浆 (TRM) 复合材料试样的拉伸行为。TRM 试样由一层碳纤维作为增强材料和铝水泥基砂浆作为基质组成。试样的主要参数是锚固方法，这是新开发的以改善复合材料的拉伸行为：展开纤维长丝的末端，使用玻璃纤维增​​强聚合物片或钢筋增强纤维长丝的末端，以及涂层纤维丝的末端带有氧化铝粉末。从测试结果中发现，大多数使用开发的锚固方法的 TRM 试样都表现出延展性。而且，使用开发的锚固方法可以将复合试件的开裂强度和峰值强度分别提高到 66.1% 和 97.9%。试样的破坏模式由碳纤维的部分断裂控制，除了基础试样和钢筋增强的试样。最后，按照 ACI 549.4R-13 中规定的指导，将 TRM 试样的拉伸应力-应变关系理想化为双线性应力-应变响应曲线。
