Previous research at Forintek Canada Corp. showed that by optimizing aspen strand alignment, strand length, strand thickness, and face-to-core (f/c) layer composition, three layer oriented strandboard (OSB) panels can be produced with bending properties significantly exceeding those of CSP commercial plywood. Also, the creep behaviour under room conditions was comparable for the two panel types. The specific objective for this year's work was to extablish the improved performance using panels produced in structural sizes and under conditions that parallel those of the industry more closely.
