Abstract

Structural polymeric composite (SPC) materials have become increasingly popular in the automotive industry due to their lightweight potential, excellent fatigue, and impact resistance, superior damping behavior, and high strength and stiffness properties. The automotive sector shows a strong interest in enhancing the repair methods for SPC. However, with immature SPC design rules, production processes, and joining technologies, the safety and efficiency of composite automotive components will heavily rely on effective structural maintenance and repair. Despite its importance, minimal progress has been made in repairing SPC materials over the past decades. Consequently, there is a pressing need to enhance composite repair practices and foster innovation in this vital area. This paper aims to address this demand by focusing on repair techniques and covering various state-of-the-art processing steps associated with SPC materials in the automotive industry. The review contributes an overview of several crucial aspects of composite repair, encompassing advanced non-destructive testing (NDT) methods for damage assessment, machining of structural composites, and surface preparation techniques. Furthermore, it delves into scarfing repair methods, such as patching and bonding, along with repair monitoring and automation, case studies, and emerging trends in composite repair technologies.

结构性聚合复合材料的修复技术：汽车视角

结构聚合物复合材料（SPC）具有轻质、抗疲劳、抗冲击、阻尼性能优越、强度和刚度高等特点，因此在汽车行业越来越受欢迎。汽车行业对改进 SPC 的维修方法表现出浓厚的兴趣。然而，由于 SPC 设计规则、生产工艺和连接技术尚不成熟，复合材料汽车部件的安全性和效率将在很大程度上依赖于有效的结构维护和修理。尽管 SPC 十分重要，但在过去几十年中，SPC 材料的修复工作进展甚微。因此，迫切需要加强复合材料维修实践，促进这一重要领域的创新。本文旨在满足这一需求，重点介绍修复技术，并涵盖汽车行业中与 SPC 材料相关的各种最先进的加工步骤。综述概述了复合材料修复的几个关键方面，包括用于损伤评估的先进无损检测 (NDT) 方法、结构复合材料的机加工以及表面处理技术。此外，它还深入探讨了修补和粘接等疤痕修复方法，以及修复监测和自动化、案例研究和复合材料修复技术的新兴趋势。

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
