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.
