Abstract
Holographic nondestructive testing (HNDT) was carried out to identify the debond areas in flat honeycomb sandwich test coupons and large panels made of aluminium facesheet and different film adhesives ( Redux 31 2, 31 2-L and 31 2-UL). The details of the development and establishment of a new (dual) vacuum stressing technique for HNDT of honeycomb panels are presented. It is found that the detectability of debonds in honeycomb panels using the dual vacuum stressing technique is independent of the facesheet material and film adhesive system used for manufacturing the panels.
