Abstract

A method of providing fastener holes in extremely hard ceramic armor comprises the steps of: PA1 (a) providing a billet of precompacted ceramic powder material; PA1 (b) drilling the desired holes in the billet; PA1 (c) preparing a plug of non-sintering material that is chemically compatible with and has compaction characteristics similar to the ceramic powder material; PA1 (d) pressing the plugs into the billet holes; PA1 (e) hot pressing the billet and plugs at conventional temperature and pressure for manufacture of a ceramic armor structure, and; PA1 (f) removing plugs by conventional tooling or sandblasting.
