Non-metallic armours like Kevlar-Epoxy Composites are finding wide usage in defense applications for fabrication of body armours for protection against projectile or splinter impacts. Estimation of the extent of post-impact damage zone is important to provide valuable inputs for effective design and fabrication of such armours. The present work involves immersion type ultrasonic C-scan of armours impacted at locations by small arms ammunition of caliber 7.62 mm. A square zone, 72 mm by 72 mm is identified around each impact Zone for scanning. At each location of the probe, ultrasonic features are extracted from digitized data and stored in the controlling PC. Dataset are subjected to systematic grouping as per the C-Link, UPGMAA algorithm and results are used for imaging the scanned zone. Areas of core damage zone are found to increase with the energy loss of the bullet. Such areas, however, are found to increase considerably when shot lodging takes place.
