Nondestructive testing and evaluation of fiber reinforced composite structures Foreword by Prof. Shandong. Tu (Academician Chinese Academy of Engineering) Preface Chapter 1 Introduction and background of fiber reinforced composite materials Chapter 2 Introduction to nondestructive testing and evaluation of fiber reinforced composites Chapter 3 Visual testing for fiber reinforced composite materials Chapter 4 Non destructive evaluation (NDE) of aerospace composites: ultrasonic techniques Chapter 5 Infrared thermography testing and evaluation of fiber reinforced composite materials Chapter 6 Terahertz testing technique for fiber reinforced composite materials Chapter 7 Application of acoustic emission for the inspection of fiber reinforced composite materials Chapter 8 Other methods Chapter 9 – Important conclusions developments and future trends Appendix A: Examples of typical standards in relation to NDT techniques for the inspection of composite structures. This book presents a detailed description of the most common nondestructive testing(NDT) techniques used for the testing and evaluation fiber reinforced composite structures during manufacturing and or in service stages. In order to facilitate the understanding and the utility of the different NDT techniques presented the book first provides some information regarding the defects and material degradation mechanisms observed in fiber reinforced composite structures as well as their general description and most probable causes. It is written based on the extensive scientific research and engineering backgrounds of the authors in the NDT and structural health monitoring (SHM) of structural systems from various areas including electrical mechanical materials civil and biomedical engineering. Pursuing a rigorous approach the book establishes a fundamental framework for the NDT of fiber reinforced composite structures while emphasizing on the importance of technique’s spatial resolution integrated systems analysis and the significance of the influence stemming from the applicability of the NDT and the physical parameters of the test structures in the selection and utilization of adequate NDT techniques. The book is intended for students who are interested in the NDT of fiber reinforced composite structures researchers investigating the applicability of different NDT techniques to the inspections of structural systems and NDT researchers and engineers working on the optimization of NDT systems for specific applications involving the use of fiber reinforced composite structures.
