This study was conducted to determine the impacts of heat treatment on lap shear
strength, density, and mass loss of black pine wood. In the study, black pine wood
boards bonded with polyurethane were subjected to temperatures of 160, 180, and
200 C for durations of 2 and 6 hours. Specimens having two layers were prepared
from untreated and treated wood for mechanical testing of bond lines. Data were
analyzed using variance analysis and Tukey’s test to determine the impacts of
changes in density and mass of heat-treated black pine wood on lap shear strength.
The results indicated that the lap shear strength of black pine wood decreased as
the intensity of heat treatment increased. The results also indicated that the minimum
and maximum percentage decreases of lap shear strength were approximately
27% for 160 C and 2 hours and 78% for 200 C and 6 hours
