Woven lattice truss sandwich (WLTS) structures with integral textile construction have excellent debonding resistance. A double-layer WLTS (DWLTS) composite was designed to improve blast resistance and maintain electromagnetic wave transmission properties of the sandwich panel. Experimental results show that the DWLTS has excellent blast-resistance and EM wave transmission characteristics.
Woven lattice truss sandwich (WLTS) structures have excellent debonding resistance with integral textile construction. As the WLTS has limited thickness, a double-layer WLTS (DWLTS) composite was designed and fabricated to improve the blast resistance of the sandwich panel, as well as keep its electromagnetic (EM) wave transmission properties. The panel was placed by two layers of WLTSs and plain fabrics, and co-cured using vacuum bag molding process to ensure the interfacial shear resistance. In-field explosion experiments reveal that the DWLTS has excellent blast-resistance and EM wave transmission characteristics. The transmission exceeds 80% in 4.5-8.5 GHz and 16-17.2 GHz, and the maximum transmittance is 98.27% at 4.9 GHz. The panel has little damage until the scaled distance is smaller than 1.026 kg/m(1/3 )with standoff distance of 0.6 m and TNT mass of 0.2 kg. No debonding was observed.
