Destruction of filled polymer targets by high-velocity impact
N. N. Pilyugin Institute of Mechanics, Lomonosov Moscow State University, Moscow, 119192
Abstract:
An analysis is made of experimental results on impact (at velocities of 0.6–6.26 km/sec) of projectiles made of Caprolon and polyethylene and compound projectiles (made of Caprolon with steel or aluminum spheres) on targets made of an epoxy resin with and without a filler (Al$_2$O$_3$) in a ballistic range. Impact on the edge surface of cylindrical targets with a characteristic size of 0.05 m is investigated. Complete fracture of the targets was recorded at velocities above 1 km/sec. The masses and dimensions of the collected fragments are subjected to statistical analysis. Average values of the fragment sizes and specific surface fracture energy are calculated.
Keywords:
ballistic experiment, high-velocity impact, filled polymer, target failure, statistics of fragments, specific surface fracture energy.
