20.500.12556/RUL-161291 Evaluation of mechanical properties and surface quality of wood from Bosnia and Herzegovina exposed to outdoor conditions This study investigated the mechanical properties of beech (Fagus sylvatica L.) and fir (Abies alba) wood from Bosnia and Herzegovina under outdoor exposure. Samples were exposed for 3-month exposure to assess bending strength, color changes, and surface quality. Results showed outdoor exposure negatively affected mechanical properties, particularly in samples with extended finger joints, causing significant surface cracks in uncoated samples. Beech wood exhibited notable color changes under exposure, with approximately 50 % darkening without coating compared to 25 % under covered conditions. Coated samples displayed minimal color changes, affirming the efficacy of surface treatment. Fir wood exhibited a roughness of 8.264 μm, while beechwood average roughness increased from 6.767 to 13.916 μm after exposure, with micro-pore development affecting water performance. Microscopic analysis identified prevalent fungal colonies, including Penicillium, Aureobasidium, Sclerophoma, and Chaetomium, underscoring their role in organic matter decomposition. This study highlights the importance of wood exposure and treatment selection for various applications. mechanical properties outdoor conditions cracks wood species mehanske lastnosti zunanji pogoji razpoke lesne vrste true false true Angleški jezik Slovenski jezik Članek v reviji 2024-09-09 11:28:19 2024-09-09 11:28:25 2025-08-08 13:41:38 0000-00-00 00:00:00 2024 0 0 Str. 1417-1431 no. 8 Vol. 12 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 2164-6341 10.32604/jrm.2024.052826 202021123 RAZ_Hasanagic_Redzo_2024.pdf RAZ_Hasanagic_Redzo_2024.pdf 1 8818CD9C913575184F94DE7BE8B7CFB7 dda9f0249a247081162a03d1368a22a108e44d1bcc393540be77ec5e890f1663 61d04040-6e8e-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190190 https://www.techscience.com/jrm/online/detail/21073 Open access 1 d7596a70-6e8d-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190189 Biotehniška fakulteta 0 0 0
