This unified approach to polymer material science covers the wide range of underlying principles: from molecular structure to material properties; from the relationships between part design, processing and performance to mechanical properties and failure mechanisms. The book stands out with many full-color graphs and figures that visually convey what polymers can--and cannot--accomplish in a world that relies on this class of materials in basically all aspects of modern life. Real-world examples and a variety of problems help the reader apply their knowledge and sharpen their problem-solving skills. Materials Science of Polymers for Engineers 3E covers the 6Ps: polymers, process, product, performance, profit, and post-consumer life (sustainability). There are three major sections in the book. -Basic Principles--covering historical background, basic material properties, molecular structure, and thermal properties of polymers. -Influence of Processing on Properties--tying processing and design by discussing rheology of polymer melts, mixing and processing, the development of anisotropy, and solidification processes. -Engineering Design Properties--covering the different properties that need to be considered when designing a polymer component from mechanical properties to failure mechanisms, electrical properties, acoustic properties, and permeability of polymers.
