Durability Of Carbon Fiber Reinforced Plastics

"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 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.

Reinforced plastics are becoming widely adopted for long-term structural use-in everything from buildings and bridges to boats and swimming pools. However, the lifetimes being sought are far greater than the whole history of reinforced plastics production! Reinforced Plastics Durability explores the strength and weathering characteristics which make the material ideal for numerous applications, but also alerting the user of wear and corrosion-with studies of the processes and mechanisms which cause the deterioration. Written especially for first-time users of reinforced plastics-engineers, designers, and managers alike-Reinforced Plastics Durability offers substantial introductory information with key concepts. Subsequent chapters examine the long-term threats to the integrity of reinforced plastics: outdoor weathering, solvent/water attack, high temperatures, and repetitive stress. To maximize durability, contributors to the book report on experience with specific applications over time; the possibility of repair; and use of computer techniques to predict durability. Despite mentioning many possible threats to durability, Reinforced Plastics Durability emphasizes the fact that reinforced plastics composites have performed very well in most of the application areas. Readers will be able to take advantage of that success-and to possibly take steps toward the next phase of refinements and improvements.

Carbon Fiber, Second Edition, brings together available information on the production, properties, application and future of carbon fibers.

Given the increasing use of fibre-reinforced polymer (FRP) composites in structural civil engineering, there is a vital need for critical information related to the overall durability and performance of these new materials under harsh and changing conditions. Durability of composites for civil and structural applications provides a thorough overview of key aspects of the durability of FRP composites for designers and practising engineers. Part one discusses general aspects of composite durability. Chapters examine mechanisms of degradation such as moisture, aqueous solutions, UV radiation, temperature, fatigue and wear. Part two then discusses ways of using FRP composites, including strengthening and rehabilitating existing structures with FRP composites, and monitoring techniques such as structural health monitoring. Durability of composites for civil and structural applications provides practising engineers, decision makers and students with a useful and fundamental guide to the use of FRP composites within civil and structural engineering. Provides a thorough overview of key aspects of the durability of composites Examines mechanisms of degradation such as aqueous solutions, moisture, fatigue and wear Discusses ways of using FRP composites, including strengthening and rehabilitating existing structures
