description: ( ? )

An ideal introductory text, this book helps readers understand and improve current manufacturing processes as well as invent novel composite processing techniques. It includes qualitative questions and fill-in-the-blank exercises along with quantitative problems. The contents covers transport equations especially geared towards polymer flows, the basics of fluid mechanics and heat transfer principles, short fiber suspension and advanced thermoplastic manufacturing methods, reaction and crystallization kinetics and permeability of fabrics, conventional assumptions in polymer composite processing, and modeling tools such as dimensionless analysis and closed forms solutions.
