Accelerated Aging of Phenolic-Bonded Hardboards and Flakeboards.

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.
