Dynamic Response Test of Double-Layer Honeycomb Sandwich Com-positePanels to Blast Impacts
[Purposes]This study aims to investigate the blast resistance performance of double-layer hon-eycomb composite panels.[Methods]The finite element analysis using LS-DYNA and experimental methods were employed to study the dynamic response of the target panels to blast waves,using two dif-ferent materials(glass fiber and Kevlar)as skins combined with Nomex honeycomb to form double-layer tandem honeycomb sandwich materials,which are taken as research objects.The dynamic response data and energy absorption of the target panels under the impact of blast waves were obtained and compared with experimental results.[Findings]The study provided data on the dynamic response and energy ab-sorption of the target panels under the impact of blast waves.[Conclusions]The honeycomb structure is the main energy-absorbing component,with the Kevlar panel showing more severe damage.
