摘要: Abstract We reported a new function of sandwich panels with truss cores, i.e., superior performance under intense local heat flux induced by continuous wave laser. To further enhance the laser resistance, lightweight ablative material and thermal insulation are filled in panel respectively. A dimensional analysis is developed to find core filler materials appropriate properties. Experiments show that compound silicone resin carbon powder, typical material, porous ceramic, significantly improve resistance compared monolithic plates unfilled panels. The full-field temperature history dynamic damage evolution back surface recorded compared, failure time reach melting point prolonged following order: plate, panel, powder. Considering design requirement such structures, relation specific weight also evaluated discussed.
