Practical Guide to the Assessment of the Useful Life of Plastics available in PDF, EPUB and Kindle. After price and delivery time, the most frequently asked question about a product is 'How long will it last?' Lifetime expectancy is often many years, the service conditions may be complex, and there is a scarcity of definitive data on durability. The situation is complicated by the fact that there are a vast number of degradation agents, service conditions, properties of importance and different plastics. There are many inherent difficulties in designing durability tests. In many cases, the time scale involved is such that accelerated test conditions are essential. Whilst large amounts of durability data are generated by accelerated methods, much of it is only useful for quality control purposes and relatively little has been validated as being realistically capable of representing service. Most assessments of the lifetime of plastics are made by considering some measure of performance, such as impact strength, and specifying some lower limit for the property, which is taken as the end point. Lifetime is not necessarily measured in time. For example, for some products it will be thought of as the number of cycles of use. The object of this publication is to provide practical guidance on assessing the useful service life of plastics. It describes test procedures and extrapolation techniques together with the inherent limitations and problems. The Guide aims to make available the wealth of information that can be applied to help maximise the effectiveness of a durability-testing programme. This guide seeks to be comprehensive but concentrates on the most common environmental effects causing degradation. The test procedures used are outlined and the relevant textbooks and international standards are well referenced. Examples of lifetime testing studies are cited. The Practical Guide will be useful for anyone responsible for designing, manufacturing or testing plastic components. It will also be of benefit to suppliers and users of end products, as assessment of useful lifetime is critical to the economics and safety aspects of any component.

Download and read online ebook Weathering of Polymers and Plastic Materials write by Luís Eduardo Pimentel Real. This book was released on 2023-09-12. Weathering of Polymers and Plastic Materials available in PDF, EPUB and Kindle. This book presents the state of the art on the weathering of polymers and plastic materials in outdoor applications, comprising natural weathering, accelerated climatic weathering, laboratory artificial accelerated weathering, and lifetime prediction methodology. It summarizes the most suitable methods of instrumental analysis to access and quantify (when possible) degradation caused by weathering, while also covering the degradation and stabilization of polymers based on environmental and artificially induced factors. Innovative polymer additives and some developments in polymeric materials designed for outdoor applications are also included, emphasizing a few selected cases. the book intends to be an important reference source for those involved in the study of the durability of polymers and plastics, production of plastics for exterior applications, chemists responsible for quality control of plastic products, and researchers and students across plastics engineering, polymer science, polymer chemistry and environmental science.

Download and read online ebook Coated and Laminated Textiles for Aerostats and Airships write by Mangala Joshi. This book was released on 2022-03-28. Coated and Laminated Textiles for Aerostats and Airships available in PDF, EPUB and Kindle. This book covers material challenges and technology innovation in coated and laminated textiles for aerostats and airships. Aerostats/airships are lighter-than-air (LTA) aircraft which are generally used in defence applications and face many harsh environmental conditions. For sustaining such conditions, there are special requirements for the material to be used in aerostats/airships which generally include a multi-layered coated/laminated textile using a textile fabric in base layer and different polymers for coating/lamination. Therefore, this book covers typical materials developed by different countries, challenges for developing material for aerostat/airship envelope and the future scope. Features: Exclusive title on materials used for LTA envelopes. Discusses material challenges such as selection of suitable fibre, polymer, additive, coating/lamination techniques, joint type and sealing techniques. Includes typical materials developed by different companies and researchers worldwide. Clearly explains technical concepts using figures, schemes and tabulated data. Includes case studies on material developed for aerostats/airships by different countries including NASA, Lockheed Martin, JAXA, ADRDE and DRDO. This book is aimed at graduate students, researchers and professionals in textiles engineering and aerospace engineering.

Download and read online ebook Advances in Structural Adhesive Bonding write by David A. Dillard. This book was released on 2010-03-31. Advances in Structural Adhesive Bonding available in PDF, EPUB and Kindle. Adhesive bonding is often effective, efficient, and often necessary way to join mechanical structures. This important book reviews the most recent improvements in adhesive bonding and their wide-ranging potential in structural engineering. Part one reviews advances in the most commonly used groups of structural adhesives with chapters covering topics such as epoxy, polyurethane, silicone, cyanoacrylate, and acrylic adhesives. The second set of chapters covers the various types of adherends and pre-treatment methods for a range of structural materials such as metals, composites and plastics. Chapters in Part three analyse methods and techniques with topics on joint design, life prediction, fracture mechanics and testing. The final group of chapters gives useful and practical insights into the problems and solutions of adhesive bonding in a variety of hostile environments such as chemical, wet and extreme temperatures. With its distinguished editor and international team of contributors, Advances in structural adhesive bonding is a standard reference for structural and chemical engineers in industry and the academic sector. Reviews advances in the most commonly used groups of structural adhesives including epoxy, silicone and acrylic adhesives Examines key issues in adhesive selection featuring substrate compatibility and manufacturing demands Documents advances in bonding metals, plastics and composites recognising problems and limitations
