Anotácia knihy

A metal part behaves almost the same on day one and ten years later, provided it isn't corroding. A polymer part almost never does. Its stiffness shifts with temperature, it creeps under a load a metal would carry indefinitely, and it can turn brittle years into service with no visible warning, because heat, oxygen, ultraviolet light, or moisture have been quietly reworking its molecular structure the whole time.

An engineer who treats a polymer data sheet the way a metal data sheet is treated, as a fixed set of numbers good for the life of the part, eventually gets surprised by it, usually as a field failure, a warped molded part, or a fitting that cracked far below its rated strength. Much of the available material on polymers doesn't close that gap, because it specializes: a chemistry-focused text stops short of manufacturing, a processing manual treats material behavior as a black box, and a design guide offers rules of thumb without showing where the numbers came from.

This book follows a single connected thread instead, from a polymer's molecular architecture through its measurable properties, through the processes that convert resin into product, to the design decisions an engineer must ultimately defend, with every relationship derived from first principles and demonstrated on a fully worked, unit-checked numerical example.

Inside, you will:

• Derive and apply the governing relationships for polymerization kinetics, crystallinity, melt viscosity, and viscoelastic response, each demonstrated on a complete, checked numerical example.
• Learn to read a calorimetry thermogram, a melt-flow-index result, and a dynamic mechanical analysis sweep well enough to translate them into an actual processing window.
• Compare commodity and engineering thermoplastics, thermosets, elastomers, and specialty polymers on the properties that genuinely decide a material selection.
• Predict fiber-reinforced composite stiffness with the rule of mixtures and a second, more broadly applicable stiffness model, and size an extrusion screw, an injection mold's clamp force and cooling time, or a thermoformed part's wall thickness.
• Apply creep-adjusted modulus, fatigue behavior, and stress-concentration principles to size a snap-fit joint, a living hinge, or a reinforcing rib for years of real service rather than a single laboratory test.

Coverage runs from polymerization mechanisms and molecular weight distribution through morphology and crystallinity, thermal and rheological characterization, mechanical and viscoelastic behavior, degradation and long-term lifetime prediction, the major thermoplastic, thermoset, elastomer, and specialty polymer families, additive formulation, fiber-reinforced composites, extrusion, injection molding, thermoforming and blow molding, polymer additive manufacturing, mechanical design for polymer components, and systematic material selection and sustainability.

This book is written for the reader who already has an engineering foundation and now needs a genuinely quantitative treatment of polymers: an upper-level engineering student, or a practicing mechanical, materials, chemical, or manufacturing engineer who needs a dependable reference for material, process, and design decisions involving plastics, elastomers, and composites.

Take the next step toward understanding and applying the ideas presented in this comprehensive guide, and start building a quantitative command of polymer behavior that a data sheet alone cannot provide.
