Abstract Fibre reinforced polymer (FRP) composites have attracted significant attention in repairing existing and deteriorating structures since the traditional rehabilitation techniques have several limitations in terms of durability, self-weight and complex installation process. Prefabricated FRP composite jackets are the preferred solution in repairing bridge piles located both underwater and above the waterline as they can be easily placed around the damaged pile to form a robust single-piece repair system. The structural continuity of the jacket in such a repair system is critical for effectively utilising its maximum strength. This study presents an extensive review of the current practices and new opportunities for using prefabricated composite jackets for structural repair. Important design considerations to effectively utilise prefabricated FRP composite jackets in repairing structures are presented and analysed. The review also identifies the challenges and highlights the future directions of research to increase the acceptance and use of emerging composite repair systems.

用于结构修复的最先进的预制 FRP 复合外套

摘要 由于传统修复技术在耐用性、自重和安装过程复杂等方面存在局限性，纤维增强聚合物（FRP）复合材料在修复现有和老化的结构方面引起了广泛关注。预制 FRP 复合护套是修复位于水下和吃水线以上的桥桩的首选解决方案，因为它们可以轻松地放置在损坏的桩周围，形成一个坚固的单件修复系统。在这种维修系统中，夹克的结构连续性对于有效利用其最大强度至关重要。本研究对使用预制复合护套进行结构修复的当前做法和新机会进行了广泛回顾。提出并分析了在修复结构中有效利用预制 FRP 复合外套的重要设计考虑因素。该审查还确定了挑战并强调了未来的研究方向，以提高新兴复合修复系统的接受度和使用率。
