Comparison of Physical and Mechanical Properties of Beech and Walnut Wood from Iran and Georgian Beech

Beech (Fagus orientalis Lipsky) forests in Iran are one of the most important sources hardwood species used for lumber, furniture, and interior object design due to its hardness, wear resistance, strength, excellent bending capabilities. Furthermore, is third country walnut wood production after China United States. Therefore, this study, we compared specific mechanical properties between beech obtained from Sangdeh (Iran) Georgia four different kinds woods Iran. Physical tests were performed according ISO 3129 (2012) ASTM (D143-14) standards. The moisture content all samples was 12% during tests. mean dry density Georgian 0.61 0.65 g/cm3, respectively, while Noor, Shahrekord, Mashhad, Mako measured 0.62, 0.59, 0.57 respectively. results showed significant differences among tree woods. Overall, strengths timber higher than that Iranian beech, which attributed timber. Noor Mashhad regions, these trees those other species. provide relevant information determinate future applications each source.
