Abstract
Since ceramics are lightweight and have a sufficient strength, they have the potential to be used as a shield material. However, their low fracture toughness and low shape imparting inhibit their actual applications. To overcome the low fracture toughness and low shape imparting, layered structures joined with resin-based adhesives were conducted for use as protection against projectile impact. As the joining layer, a certain thickness above a certain level seemed to be required. No clear effects could be seen by changing the resin’s composition and type. A backup plate, even thin, effectively reduced the debris scattering from the layered structures.
