The aim is to evaluate the structural performance of a hybrid composite sandwich structure under low-velocity impact loads.
Designed a dual-core hybrid composite sandwich structure with aluminum honeycomb and PVC foam cores.
Conducted low velocity impact tests with energy levels from 12 J to 150 J.
Investigated different stacking arrangements and foam core thicknesses to assess their effect on impact performance.
The optimal panel configuration demonstrated an energy absorption efficiency of 83.9%.
The highest specific energy absorption was 1.41 J/g at perforation impact energy.
Various damage mechanisms including indentation and core crushing were analyzed post-impact.
