DescriptionSpecimens of phenolic-bonded flakeboard, vertical-grain southern pine and Douglas-fir, and marine-grade Douglas-fir plywood were exposed to four accelerated aging situations. These consisted of: 1) Multiple cycles of boiling and elevated-temperature drying, 2) multiple cycles of vacuum- pressure soaking and intermediate-temperature drying, 3) the six-cycle ASTM D-1037 exposure and, 4) continuous exposure to weathering at the Madison, Wis. site. Thickness change and bending strength, bending stiffness, and internal bond strength retention were measured after various numbers of exposure cycles, or time of exposure. The phenolic- bonded flakeboards retained enough strength and stiffness during accelerated aging to indicate they might be used satisfactorily in structural applications where conventional wood products are now used.
