A review of the systematic progress of this emerging class, this work provides a broad overview of shape-memory polymers (SMP) and their composites. This text presents detailed information on the wide range of SMP applications, including aeronautics, astronautics, biomedicine, and the automobile industry. Each chapter discusses an important aspect of these novel smart materials, from their properties and fabrication to the actuation approaches that can be used to trigger shape recovery. This comprehensive book also covers topics multifunctional SMPs, their composites, and SMP-based composite materials.
