Durability of Resin-Treated Paper Honeycomb Core.

PB2006102895

Publication Date	1940
Personal Author	Boller, K. H.
Page Count	32
Abstract	This report presents the results of tests to determine the durability of resin-treated paper honeycomb core. Durability was determined by flatwise compression and tension tests of core alone and core in sandwich with thin plywood and with aluminum facings that had been exposed to outdoor weathering and to accelerated aging. The investigation showed that facings provided enough protection to core so that weathering for 5 years had only slight deleterious effect on the core. Bare core, however, retained only about 35 percent of its tensile and 55 percent of its compressive strength after 5 years of weathering. Accelerated aging had little effect on core strength.
