| 摘 要： | 针对现有复合材料加强筋存在的弹性模量低、断裂延伸率小、成本高等问题, 以成本低廉的钢纤维作为主要增强材料, 建立了一种新型混杂型复合材料加强筋的理论模型。分别制备了玻璃纤维复合材料加强筋和新型混杂型复合材料加强筋试样, 测试并分析了其单轴拉伸行为, 并进行了加速腐蚀试验。结果表明: 这种新型混杂型复合材料加强筋的弹性模量达142 GPa , 与玻璃纤维复合材料加强筋相比, 具有耐腐蚀、韧性好、成本低的特点。 |

| Abstract: | A new theoretical model of the hybrid composite rebar is proposed to counter the disadvantages such as low elastic modulus, low elongation after break and high cost of current composite rebars. The glass composite rebars and hybrid composite rebars were fabricated. The single axial tensile behavior and accelerating corrosion properties were tested and analyzed. The results show that the tensile modulus of the new hybrid rebar is 142 GPa. Compared with the glass composite rebar, the new hybrid composite rebars possess the characteristics of corrosion resistance, good ductility and low cost. |
| Keywords: | hybrid composite rebar ductility modulus |
