Download or read book Fatigue and Tribological Properties of Plastics and Elastomers written by Laurence W. McKeen and published by Butterworth-Heinemann. This book was released on 2009-11-17 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Fluoropolymer Additives written by Sina Ebnesajjad and published by William Andrew. This book was released on 2011-12-16 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the applications of fluoropolymer additives have expanded significantly, with even the meaning of 'fluoropolymer additives' expanding from relatively the narrow definition of PTFE powder fillers to a wide variety of fluoropolymer elastomers, used as a processing aid for plastics processing such as extrusion, injection molding, and film blowing. The benefits of fluoropolymer additives used in plastics are the elimination of sharkskin defects, increases in process speed and output (up to 20%), the reduction of die build up, the reduction of gels and optical defects, etc. In addition, fluropolymer additives are being increasingly used in inks, lubricants, and coatings. For example, in the coating industry fluoropolymer additives can increase the life cycle of exterior coatings due to their excellent weatherability and subsequently increase the time between recoats. Engineers and scientist involved in polymer processing need practical information about these additives, their applications, and proper and safe handling. Until now much of this information has been difficult to obtain because of commercial secrecy. Existing books on polymer additives only include the briefest of coverage of fluoropolymer additives. In this first book on an additive group of growing importance, the authors review the commercial additives available on the market. The applications chapters provide readers with a step by step description of techniques to select and incorporate these additives in various products. UNIQUE FEATURES AND BENEFITS: Fluoropolymer additives are becoming more widely used with key applications including use as a polymer processing aid (increasing speed and reducing faults) and as an additive to lubricants, inks and coatings. This book is the only practical guide available to the selection and use of fluoropolymer additives, and will help readers to optimize existing fluoropolymer applications and implement new ones. Fluoropolymers are known as an area where detailed information is hard to come by. In this book two former DuPont employees provide a wide range of industry sectors with the essential practical information and data they need to realize the full benefits of fluoropolymer additives. Written for practicing engineers, Ebnesajjad and Morgan take a highly practical approach to the subject, based on real-world experience and case studies.

Download or read book Solid State Characterization of Pharmaceuticals written by Richard A. Storey and published by John Wiley & Sons. This book was released on 2011-03-31 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of solid state characterization is central to the pharmaceutical industry, as drug products are, in an overwhelming number of cases, produced as solid materials. Selection of the optimum solid form is a critical aspect of the development of pharmaceutical compounds, due to their ability to exist in more than one form or crystal structure (polymorphism). These polymorphs exhibit different physical properties which can affect their biopharmaceutical properties. This book provides an up-to-date review of the current techniques used to characterize pharmaceutical solids. Ensuring balanced, practical coverage with industrial relevance, it covers a range of key applications in the field. The following topics are included: Physical properties and processes Thermodynamics Intellectual guidance X-ray diffraction Spectroscopy Microscopy Particle sizing Mechanical properties Vapour sorption Thermal analysis & Calorimetry Polymorph prediction Form selection

Download or read book Acousto Ultrasonics written by J. Duke and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finding and slzmg cracks and other crack-like discontinuities has been the center of attention for scientists and engineers developing and using nondestructive evaluation (NDE) technology. However, with advanced mate rials being "engineered" and used in critical structural components, a new for NDE has emerged. Whereas many traditional engineering materi challenge als fail due to the initiation and self-similar propagation of a crack, reinforced composite materials degrade and fail in a manner more analogously to the collapse of a structure. Consequently the NDE of such materials involves assessing the combined effect of the material's damaged condition rather than identifying and sizing single critical imperfection. In 1979 Alex Vary, seeking to address the challenge confronting the NDE of advanced fiber reinforced composite materials began work on a new method of materials characterization. Focusing on the problem of evaluating graphite fiber reinforcedl epoxy laminated plates; Vary used a piezoelectric transducer to excite a mechanical disturbance in a plate and, with a sensi tive piezoelectric transducer monitored the disturbance on the same surface of the plate. (Placing the transducers on the same surface was primarily for practical purpose but their displacement in the direction of anticipated service load was of fundamental significance!) To quantify this observation, he counted the number of excursions, of the resulting electrical signal, above a arbitrary voltage threshold; a procedure frequently used for acoustic emission signal analysis.
