SANDSTONE TARGET TEST
A test was conducted to measure perforation performance in a sandstone target.
For this test, two identical sandstone targets were prepared. A test apparatus was configured to test fire a conventional shaped charge of known performance with and without a ReCo™ propellant cap. The test was conducted at room temperature and atmospheric conditions.
After the sandstone targets were perforated, molten aluminium was poured into the target entry holes to create a mould of the perforation tunnels. The results show that the composite charge created a tunnel with significant improvement in both penetration and perforation tunnel volume. The mould from the composite charge shows the presence of a fractured-wing along one axis of the target.
