    Abstract

    The purpose of this study was to experimentally characterize the compressive behavior of square-cell titanium honeycomb cores according to the American Society of Testing and Materials Standard C365-05. By varying the honeycomb cell size and height, as well as the foil thickness, many configurations of titanium honeycomb were manufactured utilizing a laser welding and expansion method. The test matrix consisted of 1080 compression specimens. The compression specimens were split evenly into stabilized and bare tests. At the conclusion of the characterization, a comprehensive statistical analysis was performed on the data. It was determined that the compressive behavior has a strong dependence on the relative density of the honeycomb. The compressive strength was found to be slightly affected by the presence of a stabilizing face sheet, and largely unaffected by specimen core height. The compressive modulus was affected by both the core height and the presence of a face sheet. The compression behavior of the honeycomb was compared with experimental results of honeycomb from existing publications and found to be consistent.
