Abstract

A Co-based superalloy honeycomb thermal protection system (TPS) panel has been fabricated. A series of strength tests such as the lateral tensile strength and flatwise compressive properties were carried out at room temperature. The tensile ultimate strength is higher than 59MPa, the flatwise compressive strength is higher than 15MPa. Two optical non-contact methods are introduced in this work. Longitudinal strains of a lateral tensile specimen were obtained using digital speckle correlation method. The equivalent elastic modulus was calculated further. Debonding defects between honeycomb core and face sheets were detected by ESSPI. The size and approximate location were decided real-time. The results show these two methods are feasible.
