ARMOR COMPONENTS COMPRISING HEXAGONAL BORON NITRIDE AND METHOD OF FORMING SAME

摘要

An armor component including a body including a ceramic component comprising hBN. In one aspect, the hBN is configured to undergo a phase change upon a projectile impact. In another aspect, the ceramic component may also have a ready state defining a hexagonal lattice structure configured to change from the ready state to an absorbed state defining a cubic lattice structure. The ceramic component may also have a ready state defining a first density and configured to change from the ready state to an absorbed state defining a second density, wherein the first density is less than the second density. In a particular aspect, the ceramic component can be configured to prevent pentration of a projectile having an energy of at least 1500 J upon impact with a strikeface of the ceramic component.
