Book SynopsisThis book offers an up-to-date, platform-independent introduction to injection molding simulation, which plays a very important role in the design of molds and molded parts as well as process development and optimization. The content is structured and conveyed within an engineering framework. Complicated mathematical derivations are avoided as far as possible.The necessary environment of the injection molding simulation is illuminated alongside, so that the creation of a suitable simulation model, the knowledge of the model-specific limits, and the interpretation of the results are possible. Guidance is also provided regarding the interpretation of results so that they can be better evaluated quantitatively.The book is designed as a textbook and thus is suitable to accompany courses covering injection molding simulation. The content is largely independent of any particular software package; however, introductory practice examples for Autodesk Moldflow Insight and Moldex3D are included as step-by-step instructions.

Book SynopsisFunctionalized polymers are macromolecules to which chemically bound functional groups are attached which can be used as catalysts, reagents, protective groups, etc. Functionalized polymers have low cost, ease of processing and attractive features for functional organic molecules. Chemical reactions for the introduction of functional groups in polymers and the conversion of functional groups in polymers depend on different properties. Such properties are of great importance for functionalization reactions for possible applications of reactive polymers. This book deals with the synthesis and design of various functional polymers, the modification of preformed polymer backbones and their various applications.Trade Review"The emphasis is on chemical synthesis of the functional groups and on various properties and applications. Properties addressed include bio sensitivity, cellulose or protein networks, conjugation, corrosion, electrical capacitance, optical activity, and biodegradability. The chapters, each written by a different author team, cover a broad range of topics from the same viewpoint. The book is well edited: each chapter starts with an introduction and ends with applications, and the overall selection of topics is sufficiently broad to benefit a wide audience. Given the emphasis on chemical synthesis and behavior, there is little focus, for example, on mechanical or adhesion properties. Each chapter has an extensive, up-to-date bibliography and can serve as the starting point for further research in this exciting, modern topic combining chemistry, materials science, and engineering."— J.

Book SynopsisKoyanagi presents a concise and practical guide to using a micromechanics approach to predict the strength and durability of unidirectionally aligned continuum carbon fiber reinforced plastics (CFRPs).As the use of composite materials in becomes more widespread in various fields, material durability is becoming an increasingly important consideration, particularly with regard to UN Sustainable Development Goals. Using more durable composite materials would help with achieving these goals. Because the failure of composite materials proceeds via the accumulation of micro failures and micro damage, a micromechanics approach is indispensable for estimating precise durability.In this practical guide, Koyanagi describes this approach and explains the precise durability of the composite materials with regard to the time dependence of micro failures. This book first explains the strength and durability of unidirectionally aligned continuum CFRPs. It then individually addresses

Book SynopsisSince their discovery in 1977, the evolution of conducting polymers has revolutionized modern science and technology. These polymers enjoy a special status in the area of materials science yet they are not as popular among young readers or common people when compared to other materials like metals, paper, plastics, rubber, textiles, ceramics and composites like concrete. Most importantly, much of the available literature in the form of papers, specific review articles and books is targeted either at advanced readers (scientists / technologists / engineers / senior academicians) or for those who are already familiar with the topic (doctoral / postdoctoral scholars). For a beginner or even school / college students, such compilations are bit difficult to access / digest. In fact, they need proper introduction to the topic of conducting polymers including their discovery, preparation, properties, applications and societal impact, using suitable examples and already

Book SynopsisThe field of bio-based plastics has developed significantly in the last 10 years and there is increasing pressure on industries to shift existing materials production from petrochemicals to renewables. Bio-based Plastics presents an up-to-date overview of the basic and applied aspects of bioplastics, focusing primarily on thermoplastic polymers for material use. Emphasizing materials currently in use or with significant potential for future applications, this book looks at the most important biopolymer classes such as polysaccharides, lignin, proteins and polyhydroxyalkanoates as raw materials for bio-based plastics, as well as materials derived from bio-based monomers like lipids, poly(lactic acid), polyesters, polyamides and polyolefines. Detailed consideration is also given to the market and availability of renewable raw materials, the importance of bio-based content and the aspect of biodegradability. Topics covered include: Starch CellTrade Review“Most chapters are brief, but generally well supported by citations to the original literature. Useful figures and photographs supplement the text. A detailed table of contents and a useful index allow easy access to information. The book is hardbound and produced to a good quality. An e-book version is available.” (Biotechnology Advances, 1 August 2014) Table of ContentsSeries Preface xiii Preface xv List of Contributors xvii 1 Bio-Based Plastics – Introduction 1 Stephan Kabasci
