Book The Interfacial Interactions in Polymeric Composites

Download or read book The Interfacial Interactions in Polymeric Composites written by Güneri Akovali and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer composites represent materials of great and of continuously growing importance. Their potential for application appears to be limitless. They have been the subject of numerous studies both at academic and industrial levels. Much progress has been made in the incisive formulation of composites; sophisticated methods of property evaluation have been developed in the past decade and many, largely empirical solutions have been proposed to resolve the problem of their long-term performance under typical conditions of use (i. e. the use of silane or titane coupling agents to enhance adhesion within composite materials). Assuredly one of the most essential factors in the performance of these systems is the condition of the interface and interphase among the constituents of a given system. It has become clear that it is the interface/interphase, and the interactions which take place in this part of a system, which determine to a significant degree the initial properties of the material. In order to achieve leadership in the formulation and application of polymer composites, it is evident that in depth understanding of interfacial and interphase phenomena becomes a prerequisite.

Book Electropolymerization on Carbon Fibers Effects on Composite Properties

Download or read book Electropolymerization on Carbon Fibers Effects on Composite Properties written by R. V. Subramanian and published by . This book was released on 1976 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interface tailoring in carbon fiber-polymer composites by means of electrochemical polymerization has been investigated. It was expected that fiber-matrix adhesion and composite mechanical properties can be modified by the electrochemical formation of polymer layers of varying structure and properties on carbon fibers prior to their incorporation in a polymer matrix. Techniques were developed first for producing thin polymer coatings on carbon fibers by using the latter as electrodes in an electrolytic cell containing the monomer. Composite specimens were prepared by the incorporation of the coated fibers in an epoxy matrix. It was demonstrated that, in fact, the effect of the surface treatment on the interfacial properties of the resulting composite was manifested in variations of the measured interlaminar shear and impact strengths of the composite specimens. The increase in interlaminar shear was considered to be the result of improved fiber-matrix adhesion when compared to composite specimens prepared from untreated carbon fibers. The corresponding reversed trend in impact strength values was attributed to the effect of excessive fiber-matrix adhesion in causing brittle failure of the composite. It was significant, when in exception to this general trend, it was also found that both interlaminar shear and impact strengths could simultaneously be increased.

Book The Structural Integrity of Carbon Fiber Composites

Download or read book The Structural Integrity of Carbon Fiber Composites written by Peter W. R Beaumont and published by Springer. This book was released on 2016-11-26 with total page 954 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a diverse compilation of inter-disciplinary chapters on fundamental aspects of carbon fiber composite materials and multi-functional composite structures: including synthesis, characterization, and evaluation from the nano-structure to structure meters in length. The content and focus of contributions under the umbrella of structural integrity of composite materials embraces topics at the forefront of composite materials science and technology, the disciplines of mechanics, and development of a new predictive design methodology of the safe operation of engineering structures from cradle to grave. Multi-authored papers on multi-scale modelling of problems in material design and predicting the safe performance of engineering structure illustrate the inter-disciplinary nature of the subject. The book examines topics such as Stochastic micro-mechanics theory and application for advanced composite systems Construction of the evaluation process for structural integrity of material and structure Nano- and meso-mechanics modelling of structure evolution during the accumulation of damage Statistical meso-mechanics of composite materials Hierarchical analysis including "age-aware," high-fidelity simulation and virtual mechanical testing of composite structures right up to the point of failure. The volume is ideal for scientists, engineers, and students interested in carbon fiber composite materials, and other composite material systems.

Book Engineered Interfaces in Fiber Reinforced Composites

Download or read book Engineered Interfaces in Fiber Reinforced Composites written by Jang-Kyo Kim and published by Elsevier. This book was released on 1998-10-21 with total page 416 pages. 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.

Book Controlled Interphases in Composite Materials

Download or read book Controlled Interphases in Composite Materials written by Hatsuo Ishida and published by Springer Science & Business Media. 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.
