    This second edition of a widely used text offers an integrated and completely up-to-date coverage of composite materials. Focusing on the relationship between structure and properties, it provides a well- balanced treatment of the mechanics and the materials science of composites, while not neglecting the importance of processing. Includes almost all essential areas necessary to understand this group of materials in detail, and how to use them for different applications. Includes special types of composites used as engineering materials, the behavior of composite materials under different types of loading conditions, composites with special property profiles, and design aspects of composites materials. This updated 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.
