Abstract:

The variety of structural panel products produced from wood increases yearly, spurred by the increasing use of a wider variety of particle geometries, board designs, manufacturing processes, and adhesive systems. This report describes the second of a series of investigations designed to obtain basic information on durability of exterior-type, wood-based panel products. In this work, results of the behavior of four exterior-type hard-board materials are compared to those of solid wood, plywood, and structural flakeboard in a previous investigation. All materials were exposed to four regimes for aging the boards 1 Cyclic boil-dry 2 cyclic vacuum-pressure, soak-dry 3 ASTM D-1037 accelerated aging and 4 outdoor weathering. Degradation was evaluated by changes in 1 Modulus of rupture, 2 modulus of elasticity, 3 internal bond strength, and 4 thickness.
