Abstract
A composite laminate material is described comprising a plurality of layers of graphite sheet material coated on at least one side thereof with a ceramic material having a density greater than about 50% of its theoretical density, preferably, up to about 95% or greater theoretical density. The ceramic material constitutes at least 90% of the thickness of the composite laminate. The composite laminate is formed by applying to one or both sides of graphite sheet material a ceramic layer compacted to at least 50% theoretical density. A plurality of layers of the ceramic coated graphite sheets are then stacked and pressure molded by conventional techniques with the various layers being adhered together using a suitable adhesive. The resulting laminate is light weight and thin but has sufficient strength to be used as armor material to protect against projectiles. The laminate material is easily shaped and cut and because of its light weight is especially useful for making body armor.
