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

The marine environment presents significant challenges for materials due to the potential for corrosion by salt water, extreme pressures when deeply submerged and high stresses arising from variable weather. Well-designed fibre-reinforced composites can perform effectively in the marine environment and are lightweight alternatives to metal components and more durable than wood. Marine Applications of Advanced Fibre-Reinforced Composites examines the technology, application and environmental considerations in choosing a fibre-reinforced composite system for use in marine structures. This book is divided into two parts. The chapters in Part One explore the manufacture, mechanical behavior and structural performance of marine composites, and also look at the testing of these composites and end of life environmental considerations. The chapters in Part Two then investigate the applications of marine composites, specifically for renewable energy devices, offshore oil and gas applications, rigging and sails. Underwater repair of marine composites is also reviewed. Comprehensively examines all aspects of fibre-reinforced marine composites, including the latest advances in design, manufacturing methods and performance Assesses the environmental impacts of using fibre-reinforced composites in marine environments, including end of life considerations Reviews advanced fibre-reinforced composites for renewable energy devices, rigging, sail textiles, sail shape optimisation and offshore oil and gas applications

Kunststoffe sind hochleistungsfähige Werkstoffe, die seit geraumer Zeit Anwendung in der Architektur finden. Sie faszinieren durch vielfältige technische Eigenschaften. Neben diesen macht ein breites Spektrum an Formgebungs- und Bearbeitungsmethoden das Material interessant für komplexe Geometrien in Verbindung mit digitalen Planungsprozessen. Nach den Pionierbauten der 1970er Jahre hat in jüngster Zeit eine Reihe von aufsehenerregenden Bauwerken erneut den Fokus auf das technische und ästhetische Potential von Kunststoffen gelenkt. Bislang fehlte allerdings eine umfassende Darstellung zur Verwendung von Kunststoff in der Architektur. Das vorliegende Buch schließt diese Lücke und bietet eine Einführung in die konstruktiven und gestalterischen Möglichkeiten des Werkstoffs. Es werden nicht nur Kunststoffe und ihre Eigenschaften, sondern auch Herstellung, Verarbeitung und Konstruktionsprinzipien beschrieben und für die Architektur relevante Kunststoffprodukte und -halbzeuge vorgestellt. Eine Auswahl von ca. 25 internationalen gebauten Projekten, geordnet nach Kunststoffarten und Einsatzgebiet, dokumentiert die Anwendungen von Kunststoff in der Architektur. Ein Ausblick erläutert Tendenzen in der Forschung.
