Abstract: Based on depth of penetration (DOP) experiments, a series of anti-penetration experiments were conducted in Glass, Carbon, Kevlar-49 and PBO plain weave fabric reinforced rubber composite targets subjected to shaped charge jet penetration. The residual penetration depths for four types of composites plate in validating targets were obtained. Deformations of F-plate and damage characteristics of weave fabric were analyzed. The space efficiency factor and the differential efficiency factor of four types of plain weave fabric composite plate were calculated. Results show that deformations of F-plate has an important impact on the fragmentation and scattering of the jet. The longer interaction regions between jet and F-plate, the more obvious of jet were disturbed. The protection ability of Kevlar-49 and PBO plain weave fabric reinforced rubber composite targets are better than the other two types of composites targets.
