The effects of absorbed moisture on the energy-dissipating characteristics of paper honeycomb were first studied in the Structural Mechanics Research Laboratory at the University of Texas at Austin and reported in 1959. In this study, results of the former study are reexamined and most of the earlier experimental work is repeated using improved techniques. Results indicate that moisture content has no significant effect on average crushing strength, or the energy-dissipating capacity of paper honeycomb until the moisture content exceeds 14 of the dry weight of the sample. Taking into consideration the slow rate at which paper honeycomb absorbs moisture from the air, it is concluded that moisture content is not likely, under ordinary circumstances, to be a significant consideration in the use of paper honeycomb as a cushioning material. This conclusion is essentially the same as the one reached as a result of the earlier study.
