Summary

Depth of penetration (DOP) testing using 7.62 mm × 51 mm M993 (WC core) simulants shot at a velocity of 907±4 m/s at 6.35 mm thick ceramic targets backed with 130 mm thick 5083 Al was used to evaluate six SiC materials having a wide range of room temperature properties. DOP values correlated well with hardness, with Knoop measurements being the best indicator of depth of penetration for the six materials tested. The DOP of solid-state sintered SiC was comparable to the commercial SiC-B material despite having more porosity and lower flexure strength and fracture toughness. The fracture mode of the two materials was very different in static testing, yet both materials produced similar diameter holes in the Al during penetration. V50 testing of selected samples using 14.5 mm BS-41 simulants showed that DOP results were a poor predictor of performance for 12.5 mm thick SiC adhered to 25.4 mm 5083 Al. The V50 of a SiC-YAG composition was similar to the reported SiC-B value, despite having three times the depth of penetration.
