"Materials Science of Polymers for Engineers" provides a unified approach to polymer materials science, and is divided in three major sections: - 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. It includes many graphs and figures to convey what polymers can - and cannot - accomplish in a world that relies on this class of materials in practically all aspects of modern life. Real-world examples and a variety of study problems help readers apply their knowledge and sharpen their problem-solving skills. The 4th edition is extensively revised, with more content on recycling and sustainability, expanded coverage of mechanical properties, updated discussion on material failure, and much more.
