Abstract

Effects of face/core debonding on the structural integrity of curved sandwich beams subjected to opening bending moments has been examined experimentally. Curved beams of glass/polyester faces and PVC H30 foam core were manufactured. Various sizes of debonds were created using thin Teflon sheets inserted at the outer face/core interface during processing. A fixture for testing curved beams in flexure was designed, manufactured and evaluated. Surface strains at the middle of the curve were recorded. Buckling of the debonded face sheet occurred followed by face/core propagation of the debond. Strength reduction of the beams under opening moments due to face/core debonding was substantial.
