- Abstract
In order to reduce the configuration weight of fixing fiber layer, hypervelocity impact test on the configuration stuffed with fiber layer which was sustained by honeycomb core was carried out, the bumper and rear plate were 1mm- thick aluminum plate with the distance of 120mm, the stuffed layer was located at the position of 100mm far away from the bumper. There were three kinds of stuffed layer configurations with the equivalent areal density to the 0.5mm-thick aluminum plate, i.e. 8 layer configuration comprised by Basalt and Aramid-III alternating in turn, 8 layer configuration comprised by Basalt and Aramid-III alternating in turn + honeycomb core with height of 20mm, 6 layer configuration comprised by Basalt and Aramid-III alternating in turn + honeycomb core with height of 20mm. The areal densities of single layer were 0.03216g/cm2, 0.00621g cm2 and 0.02425g/cm2 for Basalt, Aramid-III and honeycomb core with height of 20mm. The configurations were impacted by the 5mm-diameter aluminum projectile with the velocity of about 5km/s. According to the hypervelocity impact test results, the performance of would be improved by the honeycomb core used to sustain the fiber layer with the decease of the weight of fixing fiber layer.
