SHAPED CHARGE ATTACK OF SPACED AND COMPOSITE ARMOUR

摘要

This paper describes the mitigation of shaped charge penetration of steel armour by the use of spaced metallic and composite plates. The target consisted of one or more steel plates of 10mm thickness some of which were backed by 25mm E-glass polyester composite panels at various additional spacings from the rearmost steel plate. A 32mm diameter shaped charge warhead was detonated at a standoff of 2CD from the frontal of the armour system. More than 600 fragments were created by penetration of a single 10mm steel plate, the spall cone (a cone containing 95% of all fragments) had an included angle of almost 80°. Placing a second 10mm steel plate 100mm behind the first reduced the number of fragments by approximately 50% with a similar cone angle. The lowest number of fragments ( < 100) resulted from a composite plate spaced behind two spaced steel armour plates. However the lowest spall cone angles ( < 40°) were achieved for a composite plate spaced behind a single steel plate.
