摘要
结合桥梁加固工程实际,选择了合适的树脂体系,应用湿法成型预浸料制造技术,在外场制备了半固化状态的碳纤维预浸带,此预浸带有一定的柔韧性,在施工过程中能与待加固界面充分的接触,达到了良好的工艺性。并对固化后的碳纤维复合材料板进行了性能测试:抗拉强度>2875MPa,弹性模量>158.5GPa,断后伸长率1.7%。
The resin systems were selected according to the bridge strengthening requirements and wet winding method was used to fabricate the half-curing prepregs outfield. The fabricated prepregs have good process performance for its flexibility, which lead the prepregs contact the strengthened surface closely. The mechanical properties of the cured CFRP were tested. The experiment results show that the tensile strength reaches 2 875 MPa and tensile modulus reaches 158.5 GPa and the failure elongation is 1.7%.
