The result of the authors? 40 years of experience in durability testing, this book describes the advanced testing methodology based on the viscoelasticity of matrix polymer. After a short introduction to the viscoelastic behavior of fiber-reinforced plastics, the text goes on to review in detail the concepts of static, fatigue and creep strengths in polymer composites. An application-oriented approach is adopted such that the concepts developed in the book are applied to real-life examples. Indispensable information for materials scientists and engineers working in those industrial sectors concerned with the development and safe use of polymer composite-based products.
Yasushi Miyano and Masayuki Nakada are Professors in the Materials System Research Laboratory at the Kanazawa Institute of Technology, Japan. Their research is focused on the prediction methodology for the long-term creep and fatigue lives of polymer composites based on the time-temperature superposition principle. Prof. Miyano and Prof. Nakada are fellows of the Japanese Society of Mechanical Engineers, the Japanese Society of Composite Materials, and the Society for the Advancement of Material & Process Engineering.
