Polyamide honeycomb cores of densities of 1.5, 3, and 6 pounds per cubic foot were evaluated in compression and shear. Compression data included properties at 75, 300, and 500 F. Effects of high humidity and water soaking on compressive properties were also measured. Proper-ties determined will enable engineers to arrive at rational designs of sandwich constructions using these cores. Descriptions of testing apparatus, testing procedures, and detailed results are included. Author-PL
