Abstract

The last several decades have witnessed remarkable advances in smart materials, which will be playing a significant role in the areas of aerospace structures, transportation vehicles, maritime and offshore structures, wind turbine blades, pipelines, pressure vessels, civil engineering structures, medical devices and implants, household products, sports, robots, electronics, etc. Basically, smart materials could find applications in all existing manmade structures or devices, simply because there is a need for these structures to be intelligent and this need in turn drives research and development in smart materials. One requirement for future intelligent structures is damage self-healing. It is highly desired that manmade structures are reliable in their design lifetime. However, uncontrolled factors and poor-quality products such as accidental loading (for instance impact loading), design faults, construction defects, and lack of maintenance, lead to structural failure at loads well below the design level or at service life well before the design lifetime. Therefore, damage self-healing is an anticipated feature for any manmade structure. Smart materials are and will continue to be the focal material for self-healing applications. In this chapter, we will first review the existing self-healing systems, and then provide an outlook for future development in this emerging area of study.
