This third edition of a bestseller offers a current perspective on the mechanics, characteristics, test methods, applications, manufacturing processes, and design aspects of composites. Highlighting materials such as nanocomposites and smart materials, the book contains new information on material substitution, cost analysis, nano- and natural fibers, fiber architecture, carbon-carbon composites, thermoplastics matrix composites, resin transfer molding, and test methods such as fiber bundle tests and interlaminar fracture measurements. It presents a new chapter on polymer-based nanocomposites. New examples and additional problems emphasize problem-solving skills used in real-world applications.
