摘要: Abstract The vibration and damping performances of hybrid carbon fiber composite pyramidal truss sandwich panels with viscoelastic layers embedded in the face sheets were investigated this paper. Hybrid containing different thickness manufactured using a hot press molding method. Analytical models based on modal strain energy approach developed ABAQUS software to estimate property structures. A set tests carried out investigate characteristics such or without layers. loss factors slender beams orientations tested determine constitutive properties parent materials for panels. numerical simulation results showed good agreement experimental tests. increased distinctly compared previous due layer sheets.
