Keywords: Composites ,Sandwich, Experimental Testing, Numerical Methods

Sandwich structures are of great importance for aircraft structures due to their high specific bending stiffness, bending strength and functional integrability. However, impact damage can provoke a significant strength and stability reduction. Computational methods for rapid and reliable design are presented together with advanced non destructive testing methods.
