The Spalling of Armour Plate and the Influence of Backing Liners

Abstract

This note examines theoretically the influence of backing liners, such as Perspex and Tufnol, on the spalling of armour plate under attack, particularly by hollow-charge jets. Very little supporting experimental work has been undertaken but the report suggests that relatively thin liners can significantly reduce or suppress spalling, with consequent reduction in behind- plate lethality. (If the liners are thick, a further reduction in lethality by spall absorption in the backing material can occur; this is not analysed in the note). Experimental work is needed to optimise this type of improved composite armour. The report also indicates possible warhead modifications to combat such improvements.
