Abstract
A composite ballistic armor or other composite component may be formed by encapsulating one or more ceramic elements in a casting shell and introducing molten base metal into the casting shell, such that the molten base metal encapsulates the one or more ceramic elements to form the composite component. Prior to the pouring process, the ceramic elements are pre-heated to, or near, the melting point temperature or pouring temperature of the encapsulating metal. Additionally, the cooling rate following the metal pour may be less than a predetermined rate for a predetermined period of time. The encapsulating metal may comprise, for example, a steel alloy, such as 4140 or 8630 AISI, a stainless steel alloy, or FeMnAl.
