Description

Comprehensively covers introductory through advanced topics on all aspects of plastics engineering with both academic and industry perspectives.

This book provides a self-contained introduction to plastics engineering. It features a unique, synergistic approach to all aspects of materials use—concepts, mechanics, materials, part design, part fabrication, and assembly—required for converting plastic materials, mainly in the form of small pellets, into useful products. It also integrates the four disparate application areas of polymers—thermoplastics, thermosets, elastomers, and advanced composites—that normally are treated as separate subjects. 

Introduction to Plastics Engineering has five parts: The first part provides a broad survey of plastics engineering and evolving concepts for plastics use. Part II introduces simple mechanics principles required for understanding the role of mechanics in plastics engineering; addresses models for the behavior of solid, fluid, and viscoelastic materials; and discusses mechanics principles underlying the stiffening of plastics by embedded fibers, and the performance of simple structural elements. Part III introduces polymers and concepts from polymer physics to explain the macro behavior of plastics and to contrast their deformation mechanisms from those of metals, and describes the structure, applications, and mechanical properties of a wide variety of industrially important plastics. Part IV addresses part shaping (part processing) and assembly issues. And Part V covers the system-like behavior of several categories of filled materials.

  • Guides readers through all aspects of plastics engineering—from introduction through advanced topics
  • An ideal reference for students and engineers—those new to plastics or highly experienced with them
  • Provides comprehensive information on a wide variety of plastics and their uses
  • Integrates four different application areas of polymers

Introduction to Plastics Engineering is an ideal text for practicing engineers, researches, and senior and graduate students in chemical, mechanical, plastics, and related disciplines.
