Given such advantages as low weight compared to strength and toughness, laminated composites are now used in a wide range of applications. Their increasing use has underlined the need to understand their principal mode of failure, delamination. This important book reviews key research in understanding and preventing delamination. The first part of the book reviews general issues such as the role of fracture mechanics in understanding delamination, design issues and ways of testing delamination resistance. Part two describes techniques for detecting and characterising delamination such as piezoelectric sensors, the use of lamb waves and acoustic emission techniques. The next two sections of the book discuss ways of studying and modelling delamination behaviour. The final part of the book reviews research on delamination behaviour in particular conditions such as shell and sandwich structures, z-pin bridging and resin bonding. With its distinguished editor and international team of contributors, Delamination behaviour of composites is a standard reference for all those researching laminated composites and using them in such diverse applications as microelectronics, aerospace, marine, automotive and civil engineering.

Fiber composites, like metals, exhibit a form of degradation in service described as fatigue. Engineers must understand composite fatigue because it is a causative agent of design and structural failures. Engineers need to increase their knowledge of the mechanisms which result in degradation in order to predict the life of a composite under specified conditions and produce composites with greater durability. This book provides an extensive account of contemporary research on fatigue from a selection of internationally recognized researchers. Part one introduces the concept, delivering a historical review of the fatigue behavior of fiber-reinforced plastics and illustrating fatigue test methods and fatigue under multiaxial stress systems. The second part reviews current research on micromechanical aspects, emphasizing long-term behavior, interface performance, delamination, and damage accumulation. The next two sections cover the analysis and testing of fatigue behavior and detail physical, micromechanical, computational, statistical, and life-prediction models for constant and variable stress. The final parts offer an overview of the wide range of composite fatigue-related problems experienced by engineers in aerospace, marine, and structural engineering.

In the last quarter century, delamination has come to mean more than just a failure in adhesion between layers of bonded composite plies that might affect their load-bearing capacity. Ever-increasing computer power has meant that we can now detect and analyze delamination between, for example, cell walls in solid wood. This fast-moving and critically important field of study is covered in a book that provides everyone from manufacturers to research scientists the state of the art in wood delamination studies. Divided into three sections, the book first details the general aspects of the subject, from basic information including terminology, to the theoretical basis for the evaluation of delamination. A settled terminology in this subject area is a first key goal of the book, as the terms which describe delamination in wood and wood-based composites are numerous and often confusing. The second section examines different and highly specialized methods for delamination detection such as confocal laser scanning microscopy, light microscopy, scanning electron microscopy and ultrasonics. Ways in which NDE (non-destructive evaluation) can be employed to detect and locate defects are also covered. The book’s final section focuses on the practical aspects of this defect in a wide range of wood products covering the spectrum from trees, logs, laminated panels and glued laminated timbers to parquet floors. Intended as a primary reference, this book covers everything from the microscopic, anatomical level of delamination within solid wood sections to an examination of the interface of wood and its surface coatings. It provides readers with the perspective of industry as well as laboratory and is thus a highly practical sourcebook for wood engineers working in manufacturing as well as a comprehensively referenced text for materials scientists wrestling with the theory underlying the subject.

Much of the early, pioneering work on the properties of composites under impact is still conceptually relevant, yet the results of many such analyses are outdated. The accuracy of these results depend specifically on the materials used (fibre, resin), interface, and method of fabrication. Development of new materials, cost effective design, and analysis and prediction of structural behaviour have all established a need for timely, wide ranging research on impact behaviour. Impact Behaviour of Fibre-Reinforced Composite Materials and Structures brings together - for the first time - state-of-the-art research from the most recent works of leading, international experts. An important new study, this book extensively investigates impact response, damage tolerance, and failure of fibre-reinforced composite materials and structure, from a number of expert viewpoints. This book explores the nature of modern polymer composites based on glass, carbon, aramid, ceramic and polymer fibres in a polymer matrix, and details various ways of analysing the impact process. Impact Behaviour of Fibre-Reinforced Composite Materials and Structures will prove itself a valuable tool for research and development engineers, structural engineers, materials scientists, designers, and students and researchers of related disciplines.

The growing use of polymer composites is leading to increasing demand for fractographic expertise. Fractography is the study of fracture surface morphologies and it gives an insight into damage and failure mechanisms, underpinning the development of physically-based failure criteria. In composites research it provides a crucial link between predictive models and experimental observations. Finally, it is vital for post-mortem analysis of failed or crashed polymer composite components, the findings of which can be used to optimise future designs. Failure analysis and fractography of polymer composites covers the following topics: methodology and tools for failure analysis; fibre-dominated failures; delamination-dominated failures; fatigue failures; the influence of fibre architecture on failure; types of defect and damage; case studies of failures due to overload and design deficiencies; case studies of failures due to material and manufacturing defects; and case studies of failures due to in-service factors. With its distinguished author, Failure analysis and fractography of polymer composites is a standard reference text for researchers working on damage and failure mechanisms in composites, engineers characterising manufacturing and in-service defects in composite structures, and investigators undertaking post-mortem failure analysis of components. The book is aimed at both academic and industrial users, specifically final year and postgraduate engineering and materials students researching composites and industry designers and engineers in aerospace, civil, marine, power and transport applications. Examines the study of fracture surface morphologies in uderstanding composite structural behaviour Discusses composites research and post-modern analysis of failed or crashed polymer composite components Provides an overview of damage mechanisms, types of defect and failure criteria

GET BOOK

This book presents novel methods for the simulation of damage evolution in aerospace composites that will assist in predicting damage onset and growth and thus foster less conservative designs which realize the promised economic benefits of composite materials. The presented integrated numerical/experimental methodologies are capable of taking into account the presence of damage and its evolution in composite structures from the early phases of the design (conceptual design) through to the detailed finite element method analysis and verification phase. The book is based on the GARTEUR Research Project AG-32, which ran from 2007 to 2012, and documents the main results of that project. In addition, the state of the art in European projects on damage evolution in composites is reviewed. While the high specific strength and stiffness of composite materials make them suitable for aerospace structures, their sensitivity to damage means that designing with composites is a challenging task. The new approaches described here will prove invaluable in meeting that challenge.
