Available in PDF, EPUB and Kindle. Book excerpt: Over the last forty years I have been lucky enough to have experienced a unique career researching and developing composite materials, in both industry and academia, during a time of unprecedented expansion in the global composites business. Over that time, I have been involved in areas as diverse as the development of new and novel fibre and composite products through to fundamental materials research. My research efforts have been focussed in three main areas; the fibre-matrix interface region, fibre reinforcements and in particular glass fibres, and the structure-(re)processing-performance relationships of reinforced thermoplastics. The published output of that work is collected together in this series of volumes. The 19 papers collected in this volume summarise my twenty-five years of research on interface and interphase carried out while I was employed in industrial Research and Development laboratories. Much of the performance of fibre-reinforced polymer composites is defined by the structure and properties of the fibre-matrix interface region in these composites. The study of adhesion in this interface region can be divided into three general question or challenges. 1) How best to measure and characterise the level of adhesion? 2) Understanding what controls, and how to optimise, the level of adhesion. 3) Relating that level of adhesion to macroscopic composite performance. The research conducted throughout my career has addressed all three of these issues at some point and so the papers is this volume will address aspects in all three of these categories.

The published output of that work is collected together in this series of volumes. The challenges faced by the experimental scientist in composite materials ranges across many scales from nanoscale to macroscale and across many disciplines from glass science, physical and organic chemistry, polymer science through to mechanics. Generating new knowledge and understanding across this spectrum of subjects often requires the development of new, or modification of existing, testing and characterisation methods. Along the way it is often necessary to re-examine the accepted understanding of existing test methods and the in-depth researching of new materials can often lead to new and improved understanding of the analysis methods themselves. The 26 papers collected in this volume summarise a forty year journey through the analysis and characterisation of fibres, sizings, interfaces and composite materials.

This book was released on 2012-12-06 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third International Conference on Composite Interfaces (ICCI-III) was held under the auspecies of ASM International, The Aluminum Company of America (Alcoa), The Edison Polymer Innovation Co. (EPIC), Case Western Reserve University, Nippon Glass Fiber Co., Nitto Boseki Co., Office of Naval Reserach (ONR), SAMPE Japan, Teijin Co., Mobay Co., Union Carbide Co., and Vetrotex Sain-Gobain. The underlying philosophy of the conference continues to be the promotion of fundamental understanding of the structure and role of composite interfaces. With the growth of composite interface studies, the research direction naturally changes from characterization and understanding of interfacial structure to controlling this structure. For this reason, the conference was subtitled, "Controlled Interphase Structure." The rather unfamiliar phrase "interphase" is used to emphasize the interfacial region whose properties are different from the bulk. The importance of the interphase to the mechanochemical properties has been rapidly recognized among composite researchers in recent years. The conference incorporated nine sessions. No concurrent sessions were planned because of the strong interest among panicipants and organizers to intennix researchers from different disciplines. Papers presented were redistributed in Pans I throught V. Because of this, both the conference and proceedings are not organized based on the traditional disciplines or materials, but rather around concepts.

Available in PDF, EPUB and Kindle. Book excerpt: Interfaces in Metal Matrix Composites, Volume 1 presents the position of the science of interfaces, as well as the necessary background for the effort in progress to apply these materials. The book discusses the mechanical and physical aspects of the interface; the effect of the interface on longitudinal tensile properties; and the effect of the filament-matrix interface on off-axis tensile strength. The text also describes the role of the interface on elastic-plastic composite behavior; the effect of interface on fracture; and the interfaces in oxide reinforced metals and in directionally solidified eutectics. The effect of impurity on reinforcement-matrix compatibility is also considered. Metallurgical engineers and people involved in the study of materials science will find the book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: Interfacial Phenomena in Composite Materials '91 is a collection of papers dealing with the science of composite interfaces, with emphasis on theoretical modeling, test methods, and characterization methods of polymer matrix, metal, or ceramic matrix composites. One paper reviews the micromechanical test methods used in evaluating mechanical properties of fiber-matrix interface. Another paper shows that the critical fiber length cannot always be considered a material constant in the framework of load transfer models based on the shear lag theory. Microwave plasma treatment is a quick technology to change fiber surface structure as the oxidation or the roughening of the fiber increases fiber-matrix adhesion. Another paper evaluates the effect of improved adhesion on mechanical performance under static, dynamic, and impact conditions. It also examines the role of fiber anisotropy on the performance of high performance polyethylene/epoxy composites. By using the Laser Raman Spectroscopy, the investigator can analyze the effects of the fiber surface treatment, the fiber modulus, the curing temperature on the Shear strength, and the fracture mechanics of the interface. The collection can be read profitably by chemists, biochemists, and academicians involved in material compound research.

Available in PDF, EPUB and Kindle. Book excerpt: The proper choice of technology is a complex decision, particularly for developing countries, as it depends not only on local needs and conditions but also, importantly, on the national political context and, increasingly, on the international environment. This technological choice carries with it the genetic code of the nation's future development. Many developing countries which lack the needed infrastructure do not have real options; others with a reservoir of scientific and engineering skills and explicit SIT strategies, can indeed choose between alternatives. Turning to the technologies themselves, these cover a wide spectrum: traditional technologies that are low-cost, low-energy and often better suited to meet basic needs; more sophisticated technologies which are highly knowledge-intensive and require large capital outlays for research, product design and manufacturing; and still others which depend upon a blending of modern technology with traditional methods to create products and processes more suited to local needs. Even within the group of advanced technologies, there is considerable differentiation, and those at the lower end of the product cycle are clearly within reach by the newly industri alizing countries.

Available in PDF, EPUB and Kindle. Book excerpt: The study and application of composite materials are a truly interdisciplinary endeavour that has been enriched by contributions from chemistry, physics, materials science, mechanics and manufacturing engineering. The understanding of the interface (or interphase) in composites is the central point of this interdisciplinary effort. From the early development of composite materials of various nature, the optimization of the interface has been of major importance. While there are many reference books available on composite materials, few of them deal specifically with the science and mechanics of the interface of fiber reinforced composites. Further, many recent advances devoted solely to research in composite interfaces have been scattered in a variety of published literature and have yet to be assembled in a readily accessible form. To this end this book is an attempt to bring together recent developments in the field, both from the materials science and mechanics perspective, in a single convenient volume. The central theme of the book is tailoring the interface properties to optimise the mechanical peformance and structural integrity of composites with enhanced strength/stiffness and fracture toughness (or specific fracture resistance). It deals mainly with interfaces in advanced composites made from high performance fibers, such as glass, carbon, aramid, ultra high modulus polyethylene and some inorganic (e.g. B/W, A12O3, SiC) fibers, and matrix materials encompassing polymers, metals/alloys and ceramics. The book is intended to provide a comprehensive treatment of composite interfaces in such a way that it should be of interest to materials scientists, technologists and practising engineers, as well as graduate students and their supervisors in advanced composites. We hope that this book will also serve as a valuable source of reference to all those involved in the design and research of composite interfaces. The book contains eight chapters of discussions on microstructure-property relationships with underlying fundamental mechanics principles. In Chapter 1, an introduction is given to the nature and definition of interfaces in fiber reinforced composites. Chapter 2 is devoted to the mechanisms of adhesion which are specific to each fiber-matrix system, and the physio-chemical characterization of the interface with regard to the origin of adhesion. The experimental techniques that have been developed to assess the fiber-matrix interface bond quality on a microscopic scale are presented in Chapter 3, along with the techniques of measuring interlaminar/intralaminar strengths and fracture toughness using bulk composite laminates. The applicability and limitations associated with loading geometry and interpretation of test data are compared. Chapter 4 presents comprehensive theoretical analyses based on shear-lag models of the single fiber composite tests, with particular interest being placed on the interface debond process and the nature of the fiber-matrix interfacial bonding. Chapter 5 is devoted to reviewing current techniques of fiber surface treatments which have been devised to improve the bond strength and the fiber-matrix compatibility/stability during the manufacturing processes of composites. The micro-failure mechanisms and their associated theories of fracture toughness of composites are discussed in Chapter 6. The roles of the interface and its effects on the mechanical performance of fiber composites are addressed from several viewpoints. Recent research efforts to augment the transverse and interlaminar fracture toughness by means of controlled interfaces are presented in Chapters 7 and 8.

This book was released on 2013-03-08 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of composite materials to engineering components has spurred a ma jor effort to analyze such materials and the structures made from them. Most researchers workin~ in mechanics of composite structures understand that composite materials pro vide umque advantages but also present complex and challenging problems to researchers. The complex inelastic behavior and variety of failure modes of composite structures are a result of the strength and stiffness properties of constituents and their complex interac tions. Macromechanical constitutive models based on gross composite properties cannot realistically represent local interactions, and thus have serious limitations. The composite materials that are of most interest to engineering applications are often "brittle" in their behavior, in the sense that the strength and life of the material systems is controlled or greatly influenced by events or processes which involve volumes of material whose dimen sions are small compared to the global dimensions of the element. This is also true in ductile systems where local nonlinearity may contribute to local behavior which controls global response.
