Abstract:

How high-temperature drying effects mechanical properties of softwood lumber was the topic of a research conference held February 25-26, 1976, at Madison, Wisconsin. Based on his experimental data for southern pine lumber dried at 240 deg F, Peter Koch found that modulus of elasticity, proportional limit, modulus of rupture, and toughness was not significantly different 0.05 level from properties of lumber dried at 180 deg F 1. Since 1976, other experiments 2-4 have yielded similar results. Also, it appears that drying for short periods at even higher temperatures will not significantly reduce major mechanical properties of Number 2 southern pine lumber. Author
