The purpose of aligning short fibers in a fiber-reinforced material is to improve the mechanical properties of the resulting composite. Aligning the fibers, generally in a preferred direction, allows them to contribute as much as possible to reinforcing the material. In some cases, the mechanical properties of these aligned, short-fiber composites can approach those of continuous-fiber composites, with the advantages of lower production costs and greater ease of production. Since its publication, this book has been consistently recognized as one of the most important contributions to this field.

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.

Second edition (1997): We have taken this opportunity to revise the original and to add new information about developments since 1990. . . . Since 1990 there have been considerable changes in the nature of the fibers being produced, the production methods and in consumers values and expectations. . . . Since 1990, the march of high-tech fibers has continued with an ever-increasing sub-division to meet the specialised applications, as in high-performance, high-function and high-sense fibers. New research and development has produced fibers with high tenacity and modulus to give the super-fibers now used as industrial materials. . . . [n]ew . . . ultrafine fibers can emulate the functionality and ambience of biological fibers. The synthetic cellulosics have made a particular resurgence since 1990, and the various solvent-spun fibers . . . are now making a great impact on the market. They now offer the processability of synthetics along with the in-built advantages of natural cotton. We hope . . . that the approach of the 1st edition is now extended to illustrate the dynamism of this frontier industry, pointing the way forward into the next century. If you think fiber technology is a mature technology, this new book may change your mind. It examines many new high-performance, application-specific synthetic fibers recently introduced. Included are details of chemistry, research and development, properties and performance, processing, and specific industrial, consumer and medical applications. This extensive survey of new fibers and fiber technology serves the information needs of all those involved in the development and commercialization of new and improved fibers. (It also provides fascinating reading for all those interested in this subject.)

This book has its recent origins in a Master's course in Polymer Engineering at Manchester. It is a rather extended version of composite mechanics covered in about twenty five hours within a two-week intensive programme on Fibre Polymer Composites which also formed part of the UK Government and Industry-sponsored Integrated Graduate Development Scheme in Polymer Engineering. The material has also been used in other courses, and in teaching to students of engineering and of polymer technology both in the UK and in mainland Europe. There are already many books describing the analysis of and mechanical behaviour of polymer/fibre composites, so why write another? Most of these excellent books appear to be aimed at readers who already have a substantial understanding of stress analysis for linear elastic isotropic materials, who are thoroughly at home with mathematical analysis, and who seem often not to need much of the reassurance which numerical examples and illustrated applications can offer. In teaching the mechanics of composites to many groups of scientists, technologists and engineers, I have found that most of them need and seek an introduction before consulting the advanced texts. This book is intended to fill the gap. Throughout this text is interspersed a substantial range of examples to bring out the practical implications of the basic principles, and a wide range of problems (with outline solutions) to test the reader and extend understanding.

The emergence of synthetic ceramics as a prominent class of materials with a unique combination of properties has been an important part of the materials-science scene over the past 20 years. These 'high-technology' ceramics have varied applications in areas utilizing their exceptional mechanical, thermal, optical, magnetic or electronic properties. A notable development of the 1970s was that of 'Si-based' ceramics (Si3N4' SiC and 'Sialons') as high-temperature engineering solids. More recently the zirconia-based ceramics have evolved as a class of material with significant improvements in fracture-toughness. In the 1980s we are on the threshold of development of ceramic-matrix composites with the promise of over coming major limitations in engineering design with 'brittle' ceramics and the development of novel properties unattainable with monolithic micro structures. Throughout this period there have been significant but less well-publicized developments in the field of glass-ceramics and glasses. It is the purpose of this publication to review selected topics within this important area of materials science. A key element in understanding the relation between properties and microstructure is a knowledge of atomic arrangement in ceramic phases. Recent developments in NMR and X-ray absorption spectroscopies have had considerable impact on studies of atomic co-ordination in glasses and crystalline ceramic materials and are reviewed in Chapters 1 and 2. Glass-ceramics are derived from the parent glasses by controlled crystal lization and have properties dictated, in part, by the efficiency of crystal nucleation within the glass volume.

Thermoplastic Aromatic Polymer Composites: A Study of the Structure, Processing and Properties of Carbon Fibre Reinforced Polyetheretherketone and Related Materials deals with the field of thermoplastic composite materials through a study of carbon fiber reinforced polyetheretherketone. The book is composed of twelve chapters. The first four chapters are an introduction and basic learning of thermoplastic composite materials. These chapters include discussions on the components of thermoplastics, product forms, and the microstructure of aromatic polymer composites. The processing and manufacturing technology, including the fundamental operations, control, and the wide implications of manufacturing the composite material, are analyzed. The service performance structure of three interactions, namely, material, design, and processing, are illustrated. The strength of thermoplastic composites is then considered through an analysis of both shear and extensions with elastic modulus, but in the case of material strength, the differences between tension and compression properties should be taken into account. The book also notes that the durability, temperature sensitivity, and environmental resistance should likewise be regarded for a structural composite to have practical value and satisfactory performance. Lastly, the text explains that the numerous applications of thermoplastic structural composites, such as in medicine, aviation, marine and space technology, automotive, and industrial machinery, are all important and a rigorous evaluation is therefore necessary. The book finally suggests that the research into the future developments in the thermoplastic structural composites and the trend toward new design strategies and processing technology are important in optimizing the composite's great potential. Industrial researchers in the field of chemistry and polymer composites, students, and academicians interested in the design and application of polymer composites will find this book relevant.

Natural Fiber-Reinforced Biodegradable and Bioresorbable Polymer Composites focuses on key areas of fundamental research and applications of biocomposites. Several key elements that affect the usage of these composites in real-life applications are discussed. There will be a comprehensive review on the different kinds of biocomposites at the beginning of the book, then the different types of natural fibers, bio-polymers, and green nanoparticle biocomposites are discussed as well as their potential for future development and use in engineering biomedical and domestic products. Recently mankind has realized that unless the environment is protected, he himself will be threatened by the over consumption of natural resources as well as a substantial reduction in the amount of fresh air produced in the world. Conservation of forests and the optimal utilization of agricultural and other renewable resources like solar, wind, and tidal energy, have become important topics worldwide. With such concern, the use of renewable resources—such as plant and animal-based, fiber-reinforced polymeric composites—are now becoming an important design criterion for designing and manufacturing components for a broad range of different industrial products. Research on biodegradable polymeric composites can contribute, to some extent, to a much greener and safer environment. For example, in the biomedical and bioengineering fields, the use of natural fiber mixed with biodegradable and bioresorbable polymers can produce joint and bone fixtures to alleviate pain in patients. Includes comprehensive information about the sources, properties, and biodegradability of natural fibers Discusses failure mechanisms and modeling of natural fibers composites Analyzes the effectiveness of using natural materials for enhancing mechanical, thermal, and biodegradable properties

This book is an extended version of the proceedings of the Symposium on Polymer Composites, Interfaces, which was held under the auspices of the Division of Polymer Chemistry, American Chemical Society (ACS) during the annual ACS meeting in Seattle, March, 1983. The importance of the interface in composite materials has been recognized since the inception of modern composite technology. Specifically, silane coupling agents were developed for glass fiber reinforced compOSites at a very early date. Ever since then the diversity of composite materials and the development of various surface treatment methods have led to the establishment of an "interface art." A trial-and-error approach has dominated the interfacial aspects of composite technology until very recently. With the advent of modern analytical techniques for surface characterization, it became possible to study detailed surface and interface structures. It was hoped that this symposium would catalyze such a fundamental and scientific approach in composite studies. For this reason, the symposium was structured to verify the influence of interfacial structures on the mechanical and physical performance of composites and to improve our knowledge of the microstructure of composite interfaces. As the word ·composite" indicates, interdisciplinary interaction is indispensable for proper understanding of multiphase systems.
