Koyanagi presents a concise and practical guide to using a micromechanics approach to predict the strength and durability of unidirectionally aligned continuum carbon fiber reinforced plastics (CFRPs). As the use of composite materials in becomes more widespread in various fields, material durability is becoming an increasingly important consideration, particularly with regard to UN Sustainable Development Goals. Using more durable composite materials would help with achieving these goals. Because the failure of composite materials proceeds via the accumulation of micro failures and micro damage, a micromechanics approach is indispensable for estimating precise durability. In this practical guide, Koyanagi describes this approach and explains the precise durability of the composite materials with regard to the time dependence of micro failures. This book first explains the strength and durability of unidirectionally aligned continuum CFRPs. It then individually addresses fiber, resin, and the interface between the two on the basis of their micromechanics and introduces these components’ time and temperature dependences. Koyanagi uses finite element analysis and theoretical models to integrate the characteristics of the three components to explain the macro properties of the CFRPs. Various characteristics regarding strength and durability of CFRPs are also presented. This book is a valuable resource for researchers in academia and industry who work with composite materials. It will enable them to design composite structures, ensure their durability, evaluate them, and develop more durable composite materials.

The usage of composites is a broad and growing area of scientific research, especially in developed and developing countries. These materials are used in a broad range of applications in both structural and civil engineering sectors. In many of these applications FRPs are exposed to one or more environmental influences, so they need to be designed to meet durability requirements to withstand even the harshest of environments. Aging and Durability of FRP Composites and Nanocomposites focuses on the latest developments in durability and long-term ageing studies of composite materials especially for those used in civil and structural engineering applications. The book will be a valuable reference resource for materials scientists and engineers who want to learn more about the long-term service life and durability behaviour of composites under different environmental conditions. - Discusses composites and polymer nanocomposites - Reviews different types of aging processes and degradation mechanisms in composites - Covers different types of accelerated aging tests - Presents theory, modeling, and simulation studies of aged composites and nanocomposites - Looks at recent trends and future possibilities

Carbon fiber-reinforced polymers (CFRP) have been widely used as externally epoxy-bonded reinforcement for repair and retrofit of existing concrete structures. As the use of CFRP in construction increases, it is essential to consider the long term behavior. In this study, concrete specimens with externally bonded CFRP composite systems were exposed to various accelerated ageing environments: different elevated temperature water immersion, varying relative humidity exposure, real-time solar exposure, pressurized hygrothermal exposure, and fatigue loading. Three-point loading test and direct tension test were used to evaluate the flexural and tensile strength of CFRP specimens. This research recommends that the durability strength reduction factor be defined as the ratio of the flexural strength of a test specimen after exposure for 60 days at 60C to the strength of a control specimen at the initiation of exposure. Test specimens, exposure environments, testing procedures, and field application environments are selected to assure uniform reporting, testing and application of durability strength reduction factors. Two exposure environments are recommended for design, wet and air. Water can diffuse through concrete and accumulate on the epoxy/concrete interface in a wet environment and is the default condition for design. An air environment precludes water accumulation but requires engineering design and validation to guarantee compliance. The resulting durability strength reduction factor may be used to (a) calculate the reduced strength for environmental exposure, (b) qualify a specific CFRP system, (c) compare durability reduction factors to those provided by system suppliers, and (d) confirm compliance with project specifications.

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 is concerned with the development and safe use of polymer composite-based products.
