    Using Thermal Modification Technology to Add Value to Small-Diameter Logs from Underutilized Species: Final Report
    (University of Minnesota Duluth, 2021-10) Donahue, Patrick K; Aro, Matthew D; Xie, Xinfeng; Larkin, Glenn
    The project investigated mechanical, physical, and biological durability of thermally modified (170°C and 180°C) white ash (Fraxinus americana), red maple (Acer rubrum), yellow poplar (Liriodendron tulipifera), Eastern hemlock (Tsuga canadensis), and balsam fir (Abies balsamea) lumber. The test results demonstrate the effect of thermal treatment on the physical and mechanical properties. The biological durability results, tested according to American Wood Protection Association(AWPA) standards, suggest one hardwood (white ash), and two softwoods (balsam fir and eastern hemlock) may meet minimum service life thresholds for AWPA above-ground-use classification.
