Fig. 7.7 DOPs of the test
the feasibility and applicability of the armor steel/ceramic/UHPCC composite target
are verified.
(2) Damage of projectiles and targets
The comparisons between the unfired and recovered projectiles are shown in Fig. 7.8.
In addition, the damage of the post-test NSC and UHPCC targets as well as the armor
steel plates and armor steel/ceramic composite plates are further shown in Figs. 7.9
and 7.10, respectively. The ceramic plates in the present test are incapable of being
recovered due to the serious fracture.
