Composites are a class of materials which possess some unique and extraordinary properties. They have received a lot of attention recently due to their role in the field of material research and also because of the advent of new forms of composites such as nanocomposites and bio-medical composites. Composite materials can be utilized in various industries such as aerospace and construction industries. This book primarily deals with the production and property classification of various composites. It covers nanocomposites, damages and fractures-theoretical and numerical modelling, and composites - physical features, designing, processing and manufacturing methods.
