Abstract:
Lead Free Electric Primers LFEP based on energetic nanocomposites were examined as a replacement for conventional lead styphnate primers. On small scale samples, outstanding all-up round action times AUR-ATs were obtained for ambient 2.92 ms and at low-temperature 3.02 ms. Large scale batch verification testing failed to meet the AUR-AT requirement of less than 3.5 ms as specified in MIL-DTL-1394G. The AUR-ATs were affected by the very long fabrication time for the primers. Usually, primer materials were made, primers loaded and rounds built in a period of 1 week. Due to technical issues, the final 500 test rounds were assembled over a period of 7 months.
