ORTHOTROPIC ELASTICITY AND STRENGTH OF APPALACHIAN HARDWOODS IN RELATION TO MANUFACTURING COMPOSITES
Investigators: Lang, E. M.
Performing Department: Forestry -- 1240
Start Date: 03/01/1997
Termination Date: 09/30/2002
Reporting period: 01/01/2001 to 12/31/2001
Progress Report:
The project has received a one-year extension. During the calendar year of 2001, a Ph.D. dissertation has been completed and all the research objectives have been achieved. The explored orthotropic properties of hardwood species were used to develop simulation-based models that are capable to predict the expected mechanical properties of structural composite lumber. Currently, results of the overall research are under organization for publication purposes. Besides the listed papers and scientific presentations, one manuscript is in press at Wood and Fiber Science, one is in review and two additional manuscripts are in preparation.

Impact:
The explored orthotropic properties of Appalachian hardwood species and the developed simulation models can be used by manufacturers of composite lumber to predict elastic and strength properties of their product.
