摘　　要：针对舰船航煤管路应急修复补强技术难度大、安全风险高、适用性数据缺乏的现状,首先在分析了典型航煤管路结构特点、渗漏原因及应急修复补强技术要求的基础上,设计了航煤管路复合材料应急修复补强技术方法,并提出了树脂体系选材和优化路径;然后,基于缺陷管路环向应力、轴向应力补强要求,设计了修复补强纤维层数;最后,制作了6种典型航煤管路渗漏结构模型,并运用上述方法进行了应急修复,随后开展了基体耐油性试验、修复后管路密性试验、强度试验和耐久性评估。试验验证结果表明:该复合材料应急修复补强方法实用可操、安全可靠,能有效解决舰船航煤管路应急修复技术难题。To deal with issues such as great difficulty in technology, high security risk and being lack of usability data in emergency repair and strengthening of warship jet fuel pipelines, the features of warship jet fuel pipelines, causes of leakage, and technical requirements of emergency repair and strengthening are analyzed. The methods of emergency repair and strengthening are designed. Then, an approach of selecting and optimizing a suitable resin system is proposed. The number of layers is calculated based on the strengthening requirement of circumferential stress and axial stress. Six lea- kage structure models of warship jet fuel pipelines are established and applied to emergency repair. The experiments of oil resistivity, tightness, strength and durability of pipelines show lhat these methods are practical, simple, safety and reliable, which resolve the difficulty in technology of emer- gency repair and strengthening of warship jet fuel.
