The third edition of Krishan Chawla's widely used textbook, Composite Materials, offers integrated and completely up-to-date coverage of composite materials. The book focuses on the triad of processing, structure, and properties, while providing a well-balanced treatment of the materials science and mechanics of composites. In this edition of Composite Materials, revised and updated throughout, increasing use of composites in industry (especially aerospace and energy) and new developments in the field are highlighted. There is a new chapter on non-conventional composites, which covers polymer, metal and ceramic matrix nanocomposites, self-healing composites, self-reinforced composites, biocomposites and laminates made of metals and polymer matrix composites. The third edition, featuring all figures in color, also includes new solved examples and problems as well as increased coverage of: Carbon/carbon brakes. Composites for civilian aircraft and jet engines. Second generation high-temperature superconducting composites. Composites for use in windmill blades. WC/metal particulate composites. Examples of practical applications in various fields are given throughout the book, and extensive references to the literature are provided. The book is intended for use in graduate and upper-division undergraduate courses, and as a reference for the practicing engineers and researchers in industry and academia.

Composite Materials Science and Engineering focuses on the structure-property relationships in composite materials. A detailed description is given of how microstructure of different fibers (such as glass, Kevlar, polyethylene, carbon, boron, silicon, carbide, alumina etc.) controls their characteristics. The important role of interface in composite materials is discussed. Up to date information about the recent advances in polymer matrix-, metal matrix-, and ceramic matrix composites is provided. Micro- and macromechanical aspects of composite materials as well as their strength, fracture, and design aspects are described in detail - always emphasizing the basic theme of how the structure controls the resultant properties. Extensive use is made of micrographs and line drawings to bring home to the reader the importance of structure-property relationships in composites. Throughout the book, examples are given from practical applications of composites in various fields. Extensive references to the literature, general bibliography, as well as practice problems are provided. The book is intended for undergraduates (senior level) and first year graduate students as well as the practicing engineer/scientist in the industry.

With contributions from leading experts in their respective fields, Metal and Ceramic Matrix Composites provides a comprehensive overview of topics on specific materials and trends. It is a subject regularly included as a final year option in materials science courses and is also of much industrial and academic interest. The book begins with a selection of chapters describing the most common commercial applications of composite materials, including those in the aerospace, automotive, and power generation industries. Section 2 outlines manufacturing and processing methods used in the production of composite materials ranging from basic aluminium matrix composites, through particle reinforced composites, to composites using novel matrix fibres such as titanium-silicon carbide and ceramics. Section 3 is devoted to the mechanical behaviour of different matrix materials and structure-property relations, with particular attention paid to failure and fracture mechanisms. The final section considers those new fibres and composite materials currently in development, including high strength copper composites, porous particle composites, active composites, and ceramic nanocomposites.

Composite superconductors offer the solution to a wide range of problems, the principal of which are thermomagnetic instability, instability of the superconducting state with respect to strong pulsed perturbations, heat release under varying external conditions, and inadequate strength and plasticity. The macroscopic properties of composite superconductors, and the processes that occur in them are studied in the rapidly developing subject of the physics of composite superconductors.

Applications of superconductivity at the boiling temperature of liquid nitrogen continue to challenge physicists, materials scientists and engineers all over the world eight years after the discovery of high temperature superconductivity. The key to a solution of today's problems lies in the optimization of the defect structure in well-oriented oxide materials as well as in a fundamental understanding of the magnetic microstructures in the mixed state and how they are affected by the crystallographic nature ('dimensionality') of these materials. Fifteen invited overview lectures as well as approximately 150 contributed papers highlight the state of the art in this important field of superconductivity and review our current knowledge of critical currents in superconductors.

Compound superconductors with the Al5 structure carry the promise of the second generation in practical superconductivity. They will provide higher operating magnetic fields at higher tem peratures than the preceding alloy superconductors. To fulfill this promise, their brittle nature must be accommodated in a fila mentary structure. Achieving this has been no simple task and imaginative research and clever production techniques have led to many usable conductor configurations. In addition, several new and exciting possibilities are being proposed; for example, in situ processing promises easier production with improved strain toler ance. It is timely, therefore, to take measure of what we have achieved and to assess our understanding so that we may choose, with some confidence, paths for future research and potential ap plications. To meet these needs, the International Cryogenic Materials Conference Board has sponsored this special topic conference on Filamentary Al5 Superconductors bringing together superconductiv ity researchers, superconducting wire producers, and high field magnet users to discuss current research problems. That the in formation exchange was intensive and successful is evidenced by the excellent papers in this volume. In order to capture some of the synergistic wisdom generated in discussions at the conference several people were asked to assemble and interpret the comments and concerns of the fusion, high energy physics, solid state phys ics, and metallurgy groups.
