The study of 5A06 aluminum alloy and aluminum matrix composite sheet behaviors of hypervelocity impact

With more frequent space launch activities, the rapid increase in the number of space debris on future space vehicles pose a threat to security. In order to research the materials of space debris, Tif/Al composite, Tif/Cf/Al composite and Cf/Al composite were fabricated by pressure infiltration technique. These materials were impacted by aluminum projectiles of different diameters from 0.8mm~2.0mm at the speed of 2.5 km/s. It can be judged from the critical diameter of the projectile staving in the material that Tif/Al composite is the best, and then the results of 5A06 aluminum alloy, Tif/Cf/Al composite materials, Cf/Al composite dropped. Measure and compare the various materials between the projectile diameter and pit depth discovery, Cf/Al composite materials, Tif/Cf/Al composite materials, Tif/Al composite materials, 5A06 aluminum projectile diameter and pit depth ratio reduced in turn.
