摘　　要：玻璃纤维复合材料在输油气管道上已有应用,但是在输送航空原油的高压管道上应用较少,由于传统修复方式存在不同程度的局限性,而玻璃纤维有较高的比强度和比模量,因此尝试采用高强玻璃纤维补强技术对航油管道缺陷进行修复,在此技术应用之前,开展了玻纤补强修复的性能测试试验验证其可靠性。本文主要采用静水压爆破试验方法进行玻纤补强的有效性验证,并对其修复效果进行分析评价。由试验结果得出,玻璃纤维复合材料依靠自身抗拉强度抑制缺陷膨胀、延迟缺陷屈服,并在管件屈服后分担主要载荷,能够达到补强修复的作用,可安全应用在航油管道的缺陷修复中。Fiberglass composite materials have been applied in oil and gas pipelines,but it is less commonly used in high-pressure pipelines transporting aviation crude oil.Due to the limitations of traditional repair methods,fiberglass has higher specific strength and modulus.Therefore,high-strength fiberglass reinforcement technology is attempted to repair defects in aviation oil pipelines.Before this technology is applied,We conducted performance tests on fiberglass reinforcement and repair to verify its reliability.This article mainly uses the hydrostatic blasting test method to verify the effectiveness of fiberglass reinforcement,and analyzes and evaluates its repair effect.According to the experimental results,fiberglass composite materials rely on their own tensile strength to suppress defect expansion,delay defect yield,and share the main load after pipe yield,which can achieve the effect of reinforcement and repair,and can be safely applied in defect repair of aviation oil pipelines.
