VARIATIONS IN THE CRUSHING STRENGTH OF PAPER HONEYCOMB

Abstract

To determine why paper honeycomb pads, in which variables such as paper weight, cell size, cell shape, and glue line widths are ostensibly constant, sometimes vary rather widely in crushing strength, thirty one precisely controlled samples were fabricated in the laboratory and crushed under dynamic loading. Results of these tests are compared in variation with corresponding results of tests of commercial honeycomb. It appears that crushing failure is governed by random processes having to do with buckling patterns, and blowout. Studies are also reported of the air pressure developed in the cells during crushing, the effect on crushing strength of specimen size and the ratio of crushing area to total specimen area, and the crushing strength at very low crushing rates.
