Hybrid lightweight composite pyramidal truss sandwich panels with high damping and stiffness efficiency

Hybrid composite pyramidal truss sandwich panels combined with multiple damping configurations are fabricated in this work. Modal and quasi-static compressive tests are carried out to investigate the damping and stiffness efficiency of the candidate structures. Experimental results show that such st...
