Tribology of Natural Fiber Polymer Composites

Environmental concerns are driving demand for bio-degradable materials such as plant-based natural fiber reinforced polymer composites. These composites are fast replacing conventional materials in many applications, especially in automobiles, where tribology (friction, lubrication and wear) is important. This book covers the availability and processing of natural fiber polymer composites and their structural, thermal, mechanical and, in particular, tribological properties. Chapter 1 discusses sources of natural fibers, their extraction and surface modification. It also reviews the thermal, structural, mechanical, spectroscopic and morphological properties of unmodified and chemically modified natural fibers such as sisal, jute, wood, bamboo and cotton together with their potential applications. Chapter 2 gives a brief introduction to the tribology of polymer composites and the role of fiber reinforcement and fillers in modifying their tribological properties. Further chapters discuss the chemical composition, physical structure, mechanical properties and tribological behaviour of polymer composites reinforced with sisal, jute, cotton and bamboo fibers. The tribological behaviour of wood polymer composites (WPCs) is also discussed. Tribology of natural fibre polymer composites is a useful reference guide for engineers, scientific and technical personnel involved in the development of natural fiber composites. In particular it will give an insight into mechanical properties and failure mechanisms in situations where wear, lubrication and friction are a problem. Examines the availability and processing of natural fiber composites and their structural, thermal, mechanical and tribological properties Explores sources of natural fibers, their extraction and surface modification as well as properties of chemically modified natural fibers Provides an overview of the tribology of polymer composites and the role of fiber reinforcement and filters in modifying tribological composites

Diffusion and transfer of knowledge in agriculture

This book focuses on innovation in the agri-food system and the new paradigm drawn by bioeconomic approaches and principles. It draws on contributions presented during the 29th EURAGRI annual conference held in Luxemburg (September 2015) as well as on other workshops organised as part of EURAGRI. EURAGRI is an informal gathering of EU research and higher education organisations and ministries interested in agri-food research. It works as a platform of exchange and discussion on topics of common interest pertaining to the organisation, orientation and outlook of agri-food research in Europe in connection with global changes.

This book focuses on innovation in the agri-food system and the new paradigm drawn by bioeconomic approaches and principles.

Open Pit Mine Planning and Design, Two Volume Set, Second Edition

Outstanding textbook designed for courses in surface mine design, open pit design, geological excavation engineering and in advanced open pit mine planning and design. The step-by-step introduction to mine design and planning enables a fast-path approach to the matter by undergraduate and graduate students. The excellent, user-friendly software guides the student through the planning and design steps, and the drillhole data sets allows the student to practice the described principles in diverse mining properties case examples. The large number of illustrative examples and case studies, together with the exercises and the reference lists at the end of each chapter, provide the student with all the material needed to study effectively the theory and application methods of open pit mine planning and design. Volume 1 deals with the fundamental concepts involved in the planning and design of open pit mines. Subjects covered are mine planning, mining revenues and costs, orebody description, geometrical considerations, pit limits, production planning, mineral resources and ore reserves, and responsible mining. Volume 2 deals with CSMine, a user-friendly mine planning and design software that was developed specifically to illustrate the principles involved when applied in practice. It includes CSMine software, a CSMine tutorial, a user’s guide and various orebody case examples. Although intended as student course material, many practitioners have used it as a practical reference guide.

Open Pit Mine Planning and Design, Two Volume Set & CD-ROM Pack, Third Edition

Building on the success of its 2006 predecessor, this 3rd edition of Open Pit Mine Planning and Design has been both updated and extended, ensuring that it remains the most complete and authoritative account of modern open pit mining available. Five new chapters on unit operations have been added, the revenues and costs chapter has been substantially revised and updated, and the references have been brought fully up to date. In addition, the pack now also includes a fully working version of the MicroMODEL mine planning software package. Volume 1 deals with the fundamental concepts involved in the planning and design of open pit mines. Subjects covered are mine planning, mining revenues and costs, orebody description, geometrical considerations, pit limits, production planning, mineral resources and ore reserves, responsible mining, rock blasting, rotary drilling, shovel loading, haulage trucks and machine availability and utilization. Volume 2 includes CSMine and MicroMODEL, user-friendly mine planning and design software packages developed specifically to illustrate the practical application of the involved principles. It also comprises the CSMine and MicroMODEL tutorials and user’s manuals and eight orebody case examples, including drillhole data sets for performing a complete open pit mine evaluation. Open Pit Mine Planning and Design is an excellent textbook for courses in surface mine design, open pit design, geological and excavation engineering, and in advanced open pit mine planning and design. The principles described apply worldwide. In addition, the work can be used as a practical reference by professionals. The step-by-step approach to mine design and planning offers a fast-path approach to the material for both undergraduate and graduate students.
