| Abstract: | This study is aimed to investigate the influence of contact materials and their surface roughness on impact sensitivity of a match head composition. It was found that there were variations to the impact sensitivity, ranging from 2 to 14.7 J. The sensitivity response was quicker in case of steel–steel anvil combinations than with aluminium–aluminium anvil and brass–brass anvil combinations. The match head composition was found to be highly hazardous at the surface roughness values of 1.67, 1.80, and 1.60 μm for steel, aluminium and brass material surfaces, respectively. Such data are not available hitherto. |
