Özet

Sandwich materials have a lightweight core and two face sheets combined with increasing the materials’ bending rigidity with low density. Sandwich materials can be designed according to structural requirements. Nowadays, airplanes, ships, space vehicles, satellites, or wind turbines require lightweight structures with easy repairing. Self-healing materials present a good opportunity for these kinds of designs to increase the systems’ life span. Damages can occur in these kinds of structures due to impact or blast, or any other unexpected reason; the structural repairing of these kinds of devices is too expensive due to difficulties in handling. Self-healing sandwich structures combine self-healing material properties with light-weighting and high bending rigidity of sandwich structures. Self-healable sandwiches give this kind of device an advantage to extend their structural life span at a low cost. This chapter presents four main topics: self-healing sandwich panels, blast phenomena and their effects on systems, finite element modeling of sandwich panels under blast loading, and finite element modeling of damaged sandwich panels with self-healing.
