Repair of Polymer Composites: Methodology, Techniques, and Challenges discusses fundamental issues related to the repair of composites and their suitability in various industrial sectors, such as aerospace, automotive, marine and construction, etc. The repair of composites is complex and requires a thorough understanding of the various types of damage mechanisms in order to apply the appropriate NDT techniques. This book explores these issues in significant detail and presents systematic procedures and methods, thus serving as a useful reference for both undergraduate and postgraduate students, academic researchers, engineers and other professionals who are interested in this exciting field of research.
