ENERGY ABSORPTION CHARACTERISTICS OF AF/ ZF HYBRIDCOMPOSITE UNDER SHPB TRANSVERSE IMPACT

The transverse impact test of AF/ ZF (Aramid Fiber/ Zylon Fiber) hybrid composite was performed bySHPB (Split Hopkinson Pressure Bar) . The loading history and displacement history of the composites with different hybrid ratios were obtained, f rom which the failure process and energy absorption characteristics were furtheranalyzed. The change t rends of BPI (Ballistic Performance Indicator) data obtained f rom SHPB are similar to thoseof the ball firing data, indicating that the transverse impact test on AF/ ZF hybrid composite has a certain referencevalue to predict the energy absorption of composites target in the ball firing.
