A major section of this book is largely devoted to chapters outlining and applying analytic methods needed for studies of nanocomposites. As such, this book will serve as good resource for such analytic methods. Scrap tires nanocomposite particles for strengthening composites is one promising approach to recycling tires and preserving resources, and investgations into the use of electric fields to reduce friction can also help protect resouces including hydrocarbon lubricants. Some of these new composites and developments could, therefore, have a positive impact on the environment. This book contains 17 chapters which have been grouped into three main parts: 1. New materials and analytic methods: This section is rich in analytic methods suitable for nanocomposites. Analytic methods include assessment of impact, studies of bending, damage assessment, models of reaction to fire, measurement of erosion wear and measurement of strain distribution. 2. New materials with unique properties: Studies on vibrations of composite plates and detailed analysis of methods of joining Cf/C and Cf/SiC to metals are presented. 3. Applications of new materials: Studies are presented on the development of new ceramic materials for rocket thrusters, new methods for preparation of tungsten carbide-cobalt nanoparticles and for the use of nanocomposites containing scrap tire particles. I am pleased to have had the opportunity to work with the authors and to have served as editor of this book which expands composite materials research into so many exciting areas of development of materials, engineering, medicine and dental restoration. X Preface The book contains a wide variety of studies from authors from all around the world. I would like to thank all the authors for their efforts in sending their best papers to the attention of audiences including students, scientists and engineers throughout the world. The world will benefit from their studies and insights. The new possibilities of the open access press bringing together such a diverse group and to disseminate widely on the web is revolutionary, and without the contributions of the group and the mechanism of InTech Open Access Publisher, this Book titled "Nanocomposites with Unique Properties and Applications in Medicine and Industry" would not be possible. I also wish to acknowledge the help given by InTech Open Access Publisher, in particular Ms. Romina Krebel, for her assistance, guidance, patience and support.
