Part of a series of core databooks within the William Andrew Plastics Design Library, Fatigue and Tribological Properties of Plastics and Elastomers provides a comprehensive collection of graphical multipoint data and tabular data covering fatigue and tribology. The concept of fatigue is very straightforward: if an object is subjected to a stress or deformation, and it is repeated, the object becomes weaker. This weakening of plastic material is called fatigue. Tribology is the science and technology of surfaces in contact with each other and therefore covers friction, lubrication and wear. The reduction of wear and fatigue and the improvement of lubrication are key bottom-line issues for engineers and scientists involved in the plastics industry and product design with plastics. Fatigue and Tribological Properties of Plastics and Elastomers, Second Edition is an update of all that has changed in the world of plastics since the 1st edition appeared nearly 15 years ago, and has been reorganized from a polymer chemistry point of view. A hard-working reference tool: part of the daily workflow of engineers and scientists involved in the plastics industry and product design with plastics The reduction of wear and fatigue and the improvement of lubrication are key bottom-line issues The data in this book provide engineers with the tools they need to design for low failure rates

For all practical purposes, the useful life of a plastic component is equal to its fatigue life under conditions of cyclic loading such as those that occur in vibration. Equally important to materials engineers and designers are abrasion, friction and wearùtribological properties. Over 80 generic families are covered including thermoplastics, thermosets, thermoplastic elastomers and rubbers. Neat resins, blends and alloys, plastics with various combinations of fillers, additives and more are covered. Also covers plastics mated to plastics and metals.

This handbook is a database reference covering fatigue behavior and friction and wear characteristics of 106 plastics and elastomers. Data presented details the differences in behavior between generic families of plastic and rubber materials. Also covered are differences within the same generic family due to factors such as temperature, test frequency, and mating surface details (in the case of tribological properties) or material characteristics, such as sample preparation and material composition. Also covered are the tribological (friction and wear) properties of plastics and elastomers. Tribological information is presented as combinations of text, graphs, and tables. Textual data are presented as concise discussions of topics relating to the friction and wear behavior of the material of interest. Graphs show how variables affect the friction and wear properties. Tables cover coefficient of friction data, wear factor (K), wear rate, PV Limits, and abrasion resistance data.

Part of a series of data-rich handbooks within the Plastics Design Library, Fatigue and Tribological Properties of Plastics and Elastomers provides a comprehensive collection of graphical multipoint data and tabular data covering the fatigue and tribological performance of plastics. The handbook is structured by grouping together plastics of similar polymer types into ten chapters. Each of these chapters is split into two sections: Fatigue Properties and Tribological Properties, and together they provide a compendium of several hundred graphs and charts, supplying the core data needed by engineers and scientists on a day-to-day basis. The data for this third edition has been updated to cover upwards of five years since the previous edition was published, and also includes an entirely new chapter covering sustainable and biodegradable polymers. The book also includes an extensive introductory section covering fatigue, what it is and how it is measured; the fundamentals of tribology; polymer chemistry and plastics composition. These chapters also provide readers with a full understanding of the data section, and how to put it to use as a hard-working information tool.

This book discusses the main issues of fabrication and design, and applications of micromachined resonant devices, including techniques commonly used for processing the output signal of resonant micro-electro-mechanical systems (MEMS). Concepts of resonance are introduced, with an overview of fabrication techniques for micromachined devices – important to understand as design options will depend on how the device will be fabricated. Also explained: excitation and signal detection methods; an analytic model of device behavior (a valuable design tool); numerical simulation techniques; issues of damping and noise for resonant MEMS; electronic interfacing; packaging issues; and numerous examples of resonant MEMS from academia and industry. Offers numerous academic and industrial examples of resonant MEMS Provides an analytic model of device behaviour Explains two-port systems in detail Devotes ample space to excitation and signal detection methods Covers issues of damping and noise for resonant MEMS, two topics of particular importance for high-Q devices

Film Properties of Plastics and Elastomers, Fourth Edition is the only data handbook available on the engineering properties of commercial polymeric films. It details many physical, mechanical, optical, electrical and permeation properties within the context of specific test parameters, providing a ready reference for comparing materials in both the same and different families. Data is presented on the characteristics of major plastic and elastomer packaging materials, with the data in this edition updated to cover the five years since the previous edition was published. The resin chapters each contain textual summary information, including category, general description, processing methods, applications, reliability, weatherability, and regulatory approval considerations for use in food and medical packaging. Provides an essential reference tool for the workflow of engineers and scientists involved in the plastics industry Details a broad range of film properties, enabling engineers and professionals to compare and select materials Provides a life-of-product approach, with coverage ranging from properties and key concepts, through to production and applications
