Nowadays, from day‐to‐day activities of human life to high‐end sophisticated applications, tribology has a role to play in any one of the aspects. Hence, the need to understand the process, materials, techniques, and mechanism related to tribological concepts is as an important factor to be considered by the research community. Moreover, tribology is a system‐dependent phenomenon that covers a wide range of science and technology fields including materials science, mechanical engineering, lubricant engineering, biomaterials, chemistry, physics, biology, and many more, encompassing micro as well as nanotechnology.
Major organizations and academic institutions in developing countries have also realized the importance of industrial tribology and its relevance to modern design and maintenance as a result of immense savings on declining material and energy losses and decrease in cost of mass production. Accordingly, the design of eco‐friendly material for the tribological components is found to be the primary factor in the energy saving sector as well as for a green environment. One such material system is the bio‐degradable natural fiber reinforced self‐lubricating polymer composite, which can be a suitable alternative for external lubricant tribo systems. Nowadays, the research advancement of degradable natural fiber reinforced polymer composites in the field of automotive, aerospace, and construction industries has been appreciable because it provides much economic benefit due to its inherent quality of higher specific strength to weight ratio. Although the structural properties are important for tribological applications, priority will have to be given for enhancing the wear and friction behavior. Natural fiber based polymer composites have attracted researchers attention for tribological applications because of their excellent structural performance and have excelled over conventional materials in industrial systems such as bearings, automobile parts, gears, and chute liners while the advantage of reinforcing two fiber materials in one matrix or one fiber in polymer blends through hybridization effect. The development of hybrid composites helps attain a combination of the exceptional mechanical properties of different fibers/fillers. Scientists have also investigated the tribological characteristics of natural fiber composites hybridized with secondary fillers with varying operational parameters such as the type of fillers, grid size, and wt % matrix. Generally, it has been found that nano‐ or micro‐sized inorganic particles can significantly influence the tribological properties of polymeric materials.
This book covers versatile topics such as tribological assessment on accelerated aging bones in polymeric condition, nano fracture and wear testing on natural bones, tribological behavior of glass fiber with fillers reinforced hybrid polymer composites and jute/glass hybrid composites, wear properties of glass fiber hybrid, and acid‐ and silane‐modified CNT filled hybrid glass/kenaf epoxy composites, hybrid natural fiber composites as a friction material, comparative wear model on hybrid natural fiber composites, tribological behavior of particulate and carbon fiber reinforced epoxy hybrid composites, and dry sliding wear behavior of copper based hybrid metal matrix composites.
We are highly thankful to all authors who contributed the chapters and provided their valuable ideas and knowledge on tribology in this edited book. We have attempted to gather all the information from recognized researchers from Malaysia, India, Brazil, and Hungary in the areas of tribological properties and have finally completed this venture in a fruitful manner. We greatly appreciate the contributors’ commitment and their support to compiling our ideas in reality.
We are highly thankful to the Wiley team for their generous cooperation at every stage of the book production.
