The article presents problems related to assessment of subsurficial damage resulting from destructive tests of light composite armours that constitute multi-layer structures made from various materials. The active method of optical lock-in thermography was used as the non destructive method of the damage area assessment. Determination of the size of internal damage area allows for comparison of armours made from various materials. Basing on the tests conducted it was found out for the light armour samples tested that the area of subsurficial damage of material from the side of impact of a projectile simulating a shell splinter can be three times larger than the projectile’s calibre; on the other side this area can be 15-times larger than the calibre.
