Book Description
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.

Book Description
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.

Book Description
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.

Book Description
The Mechanics of Adhesion shows that adhesion science and technology is inherently an interdisciplinary field, requiring fundamental understanding of mechanics, surfaces, and materials. This volume comprises 19 chapters. Starting with a background and introduction to stress transfer principles; fracture mechanics and singularities; and an energy approach to debonding, the volume continues with analysis of structural lap and butt joint configurations. It then continues with discussions of test methods for strength and constitutive properties; fracture; peel; coatings, the case of adhesion to a single substrate; elastomeric adhesives such as sealants. The role of mechanics in determining the locus of failure in bonded joints is discussed, followed by a chapter on rheology relevant to adhesives and sealants. Pressure sensitive adhesive performance; the principles of tack and tack measurements; and contact mechanics relevant to wetting and surface energy measurements are then covered. The volume concludes with sections on fibermatrix bonding and reinforcement; durability considerations for adhesive bonds; ultrasonic non-destructive evaluation of adhesive bonds; and design of adhesive bonds from a strength perspective. This book will be of interest to practitioners in the fields of engineering and to those with an interest in adhesion science.

Book Description
Glass fibres are melt-spun, silica-based inorganic materials. Their main application is in glass fibre-reinforced composites, which account for more than 90% of all fibre-reinforced composites currently produced. Nevertheless, improvement of the key properties of composites remains challenging. The objective of this reprint is to focus on actual research topics related to glass fibres comprising multifunctional nanostructured surfaces, e.g., graphene, which can lead to electrically conductive fibres and their interphases in composites that are capable of uptake under a variety of mechanical, chemical, humidity, and thermal conditions for in situ sensing functions. Sizing of glass fibres help to protect the filaments from failure during processing and improves wetting and adhesion strength. Furthermore, the interphase may be varied by suppressing or promoting heterogeneous nucleation of a thermoplastic matrix and, thus, the transcrystalline layer can improve the mechanical performance. Improved interfacial shear strength was shown with chitosan as a coupling agent in phosphate glass fiber/polycaprolactone composites. Modulus mapping of plasma-synthesised interphases in glass fibre/polyester composites was used to examine the local mechanical properties across the interphase region. In addition, numerous analytical techniques were applied to investigate changes within the surface of unsized boron-free E-glass fibers after thermal conditioning at temperatures up to 700 °C.

Book Description
This volume consists of the state-of-the-art reports on new developments in micromechanics and the modeling of nanoscale effects, and is a companion book to the recent Kluwer volume on nanomechanics and mul- scale modeling (it is entitled Trends in Nanoscale Mechanics). The two volumes grew out of a series of discussions held at NASA Langley Research Center (LaRC), lectures and other events shared by many researchers from the national research laboratories and academia. The key events include the 2001 Summer Series of Round-Table Discussions on Nanotechnology at ICASE Institute (NASA LaRC) organized by Drs. V. M. Harik and M. D. Salas and the 2002 NASA LaRC Workshop on Multi-scale Modeling. The goal of these interactions was to foster collaborations between academic researchers and the ICASE Institute (NASA LaRC), a universi- based institute, which has pioneered world-class computational, theoretical and experimental research in the disciplines that are important to NASA. Editors gratefully acknowledge help of Ms. E. Todd (ICASE, NASA LaRC), the ICASE Director M. D. Salas and all reviewers, in particular, Dr. B. Diskin (ICASE/NIA, NASA LaRC), Prof. R. Haftka (University of Florida), Dr. V. M. Harik (ICASE/Swales Aerospace, NASA LaRC), Prof.
