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.
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.
