Abstract
There is disclosed a laminated ceramic structure including a facing member and a backing member, the two members being bonded together either directly or through an intermediate layer, the facing member being formed from a very hard ceramic such as a carbide having a KHN.sub.100 value in excess of 1000 kg/mm.sup.2, the backing member being a glass or glass-ceramic matrix having an enhanced capability or absorbing impact energy, preferably being fiber reinforced and having an energy absorbing capacity in excess of 10 KJ/m.sup.2.
Claims14
A laminated ceramic structure comprising a facing member bonded to a backing member, the facing member being composed of a very hard ceramic having a KHN.sub.100 value in excess of 700 kg/mm.sup.2 selected from the group consisting of SiC, B.sub.4 C, TiB.sub.2, SiON, and Al.sub.2 O.sub.3, each in monolithic form, and a glass-ceramic reinforced through the presence therein of whiskers, and the backing member being a composite having an impact energy absorbing capacity in excess of 10 KJ/m.sup.2 in an unnotched condition composed of a glass or glass-ceramic matrix reinforced through the presence therein of fibers.
