A composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure, differentiating composites from mixtures and solid solutions.

In the present book, ten typical literatures about composite material published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on hybrid composite material, flame retardant material, robotic materials, fibre-reinforced polymer, metal matrix composites etc. We hope this book can demonstrate advances in as well as give references to the researchers, students and other related people.
