Recent investigations into blast-resistant properties of polyureas and other multi-phase polymeric elastomers indicate that they can dissipate broad bands of frequencies such as those encountered in blast events. In this unique book, Elastomeric Polymers with High Rate Sensitivity, Dr. Roshdy Barsoum and expert contributors bring together the cutting-edge testing methodologies, material properties, and critical design data for engineers seeking to deploy this technology. Where conventional methods of resisting blast, shockwave, and penetration are expensive, time-consuming and impractical, high-strain rate elastomeric polymers (HSREP) can be cheaper, quicker, and more easily applied to new and old materials alike. This book aids both military and civilian engineers in a range of applications, from buildings and tunnels to lightweight armor, ships, and aircraft. The book features constitutive models for software developers designing with these advanced polymers, as well as a discussion of the mechanisms of interaction between high-strain rate polymers and other materials. It also thoroughly covers HSREP engineering methods to achieve other unique properties, such as fireproofing. Material properties and design data included to enable engineers to successfully deploy this technology Cheaper, quicker, and more easily implemented than traditional methods of increasing blast and ballistic performance A how-to guide to the engineering of high strain rate elastomeric polymers to achieve other useful properties, such as fireproofing

This book comprehensively discusses essential aspects of terminal ballistics, combining experimental data, numerical simulations and analytical modeling. This new, 3rd edition reflects a number of recent advances in materials science, such as the use of polyurea layers on metallic plates in order to improve their ballistics. In addition, more data and analyses are now available on dwell and interface defeat in ceramic tiles coated with polymers, and are presented here. Lastly, the new edition includes new results, numerical and empirical, concerning the DIF issue in brittle solids, as well as the “upturn” phenomenon in the stress–strain curves of ductile solids.The author also added a new analysis of concrete penetration experiments which accounts for the scaling issue in this field. This is a new,and important, addition which we are happy to announce. They also added some new insights into the interaction of EEP’s and FSP projectiles with metallic plates. Throughout the book, the authors demonstrate the advantages of the simulation approach in terms of understanding the basic physics behind the phenomena investigated, making it a must-read for all professionals who need to understand terminal ballistics.

There is considerable interest within the polymer industry in developing methods to modify existing polymer systems to achieve improvements in their functional or engineering properties. The chemical treatment of polymers, either prior to or during processing, represents an inexpensive and rapid way of achieving these modifications, and a great deal of research is underway, directed at improving both the understanding of the processes involved and the development of the practical techniques employed. The improvements obtained by chemical treatment range from subtle alteration of the chemical properties of a polymer to wholesale changes in the physical, mechanical and chemical properties, with the current favourable economics ensuring that industry will continue to exploit the technique in the search for improved polymer materials. Written by an international team of authors, drawn from both basic and applied research programmes in industry and academia, and with a strong emphasis on the underlying chemistry, this book forms a timely, concise and accessible evaluation of the most promising technologies developed to date. Chemists, technologists, materials' scientists and engineers working in all areas of the polymer industry, along with academic researchers in those fields, will find this book an essential source of reference in the course of their work.

As the first polymer book to receive the CHOICE Outstanding Academic Title distinction (2007), Introduction to Polymer Chemistry provided undergraduate students with a much-needed, well-rounded presentation of the principles and applications of natural, synthetic, inorganic, and organic polymers. With an emphasis on the environment and green chemistry and materials, this second edition continues that tradition, offering detailed coverage of natural and synthetic giant molecules, inorganic and organic polymers, elastomers, adhesives, coatings, fibers, plastics, blends, caulks, composites, and ceramics. Using simple fundamentals, the author shows how the basic principles of one polymer group can be applied to all of the other groups. He covers synthesis and polymerization reactions, reactivities, techniques for characterization and analysis, energy absorption and thermal conductivity, physical and optical properties, and practical applications. This edition also addresses environmental concerns and green polymeric materials, including biodegradable polymers and microorganisms for synthesizing materials. Brief case studies are woven within the text as historical accounts to illustrate various developments and the societal and scientific contexts in which these changes occurred. Introduction to Polymer Chemistry, Second Edition remains the premier text for understanding the behavior of polymers while offering new material on environmental science. Building on undergraduate work in foundational courses, the text fulfills the American Chemical Society Committee on Professional Training (ACS CPT) in-depth course requirement.

Pressure-Sensitive Adhesives and Applications, Second Edition explains how pressure-sensitive adhesives (PSAs) work, why they are used, and the technology used to manufacture them. This second edition features the latest developments in the field. Dr. Benedek discusses the factors that affect the rheology and special flow characteristics responsible for the adhesivity of liquid and solid PSAs. His book explores the viscoelastic behavior of PSAs, and compares them to plastics, rubbers, and polymers properties and examines the parameters that influence the conversion process of PSAs from the coating of carrier materials to the properties of the final laminate. The author covers adhesion/cohesion balance, time-temperature dependence of pressure sensitivity, chemical composition, coating properties, and coating processes affect the adhesive properties of PSA and their end products and how application-specific performance indices are used to determine the formulation and manufacture of raw materials. In addition, up-to-date coating machines, converting technology, and environmental considerations in the manufacture of PSA final products as well as industry-specific methods of testing for quality assurance and control are discussed. Pressure-Sensitive Adhesives and Applications, Second Edition combines the theoretical basis of pressure sensitivity with the practical aspects of manufacturing, testing, and use of PSAs. Readers are offered an exhaustive as well as comparative look at the engineering of plastics, adhesives, and pressure-sensitives, resulting in an indispensable, up-to-date reference for adhesive and polymer chemists and technologists.

Highlights: Failure crack sensitivity in polymers is examined. Experimental failure behaviour of cracked sheets are presented. Different strain rates are considered. Digital image correlation technique is used for displacement and strain measurements. Crack paths at different strain rates are determined experimentally. Abstract: Elastomeric polymers usually show a very low elastic modulus entailing a soft behaviour and a very high deformation capability. This macroscopic behaviour is determined by their microstructure which is characterized by a complex and entangled network of very long linear chains jointed together in some points called cross-links. Because of such a peculiar microstructure, the mechanical response (often time-dependent) of elastomeric polymers to external loads or deformations cannot be described by the classical theories developed for standard materials – such as the ones whose response depends on their crystalline structure (e.g. metal, ceramics, etc.) – since such polymers usually neglect entropic-related effects that are fundamental in highly deformable amorphous materials. In the present paper, the response of elastomeric plates containing a central crack under a tensile strain applied at various rates is experimentally analyzed giving particular emphasis on the observations of the full-field strain maps determined by means of some digital image correlation techniques. Some relaxation tests are performed, and the defect sensitivity of the material is discussed in relation to the applied deformation rate.

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications. During World War II, a widespread use of polyurethanes was first seen, when they were used as a replacement for rubber, which at that time was expensive and hard to obtain. During the war, other applications were developed, largely involving coatings of different kinds, from airplane finishes to resistant clothing. Subsequent decades saw many further developments and today we are surrounded by polyurethane applications in every aspect of our everyday lives. While polyurethane is a product that most people are not overly familiar with, as it is generally "hidden" behind covers or surfaces made of other materials, it would be hard to imagine life without polyurethanes.
