COMPARATIVE EVALUATION OF PAPER HONEYCOMB TESTING

Abstract

Results of honeycomb tests performed in the Engineering Mechanics Research Laboratory are compared with the results of tests performed at Natick Laboratories on comparison samples. Two materials, one with a crushing strength of approximately 6300 psf, and the other with a strength of approximately 12,000 psf were included in the program. The data from both the Natick tests and the EMRL tests were evaluated using a hand smoothing procedure and a computerized mathematical curve fitting procedure. Standard deviations for sample results reduced by the latter method are consistently larger than those reduced by the former method. In general, the latter method is preferable, however, because of its greater objectivity. Methods for inferring from sample tests, the properties of an entire shipment, are discussed.
