Textbook in PDF format This book aims to explore the field of tribology in micro- and nano-reinforced composites to enhance material performance across a range of applications. Researchers and engineers are actively researching different reinforcement configurations and material combinations to develop composites with superior tribological properties. This research will lead to more efficient and reliable engineering solutions. Micro- and Nanocomposites: A Tribological Viewpoint will include a brief examination of previous reinforcement techniques and their impact on composite materials. It will also analyze how changes in tribological parameters affect material surface behavior. Understanding the role of tribology is crucial in assessing the performance of reinforced composite materials, especially in sustainable applications. A key focus of the book will be the significance of reinforcement selection from a tribological perspective in studying the environmental impact of modern industrial practices. Case studies are presented at the end of the book to illustrate the key principles discussed throughout. This book is suitable for researchers, professionals, corporations, and individuals in higher education courses. It can also serve as a valuable reference for those studying advanced composite materials.
