In this paper, the honeycomb sandwich panel (HSP) reinforced with bi-layer Ceramic (B4C)/Aluminum (Al7075-T6) facesheets is proposed to be used as a shield for spacecraft against meteoroid orbital debris. A modeling strategy based on Lagrange Finite Element-Smoothed Particle Hydrodynamics (FEM-SPH) coupled method to predict the damage characteristics and the hole morphology is presented for the proposed shielding subjected to hypervelocity impact. The results show good agreement with the experimental data. Based on this investigation, significant improvement in resistance capacities is obtained using the bi-layer B4C/Al7075-T6 facesheets compared to monolayer concepts for HSP.
