Transparent ceramic composite armor

摘要

Transparent ceramic armor consisting of a light weight composite formed by utilizing a face plate of transparent aluminum oxide or transparent magnesium oxide with a back-up plate of transparent plastic and the two plates bonded together with a transparent adhesive. This composite on test affords complete ballistic protection against 0.30 AP M2 projectiles at 0 DEG obliquity with a muzzle velocity of 2770 ft. per sec.
