N2 - A series of hypervelocity impact tests were performed onto aluminum mesh/plate shields with MLI (Multi Layers Insulation) by a two-stage light gas gun launching 2017-T4 aluminum alloy sphere projectiles. The diameter of projectiles was 3.97mm. Impact velocities of AL-spheres were varied between 2.95km/s and 4.65km/s. The impact angle was 0°. The fragmentation and dispersal of hypervelocity particle against shield varying with MLI blanket position were analyzed. The protection performance of bumper attached MLI against hypervelocity projectiles impact was assessed. It was found that MLI blanket had a significant effect on small debris, so that a MLI blanket shouldn't be placed on the first layer, but when a MLI blanket was on top of the rear wall, performance of aluminum mesh/plate shield can be elevated, because microstructure of MLI blanket induced multiple shocks to the debris cloud generated by the projectile impact with the bumper.
