20.500.12556/DiRROS-23425 Natural exposure comparison of timber joints bonded with polyurethane adhesive in two climatic conditions The increased use of engineered wood in the built environment is attracting much attention because of the significant sustainable attributes. The formation of high quality reliable structural adhesive bonds is essential during the manufacture of such products. This research examines and compares the performance of bonded European beech and Radiata pine subject to natural weathering, comparing untreated, preservative treated and mineralized wood. Bonded joints were naturally weathered in Slovenia and New Zealand, respectively. The fracture energy was evaluated through Mode I fracture tests using the double cantilever beam arrangement at various ageing stages. FTIR analysis was conducted to assess chemical changes in the adhesives and wood substrate. The research provides insights into the interactions between ageing, wood species, and adhesive performance, enhancing timber structures sustainability. durability weathering climate adhesive bond mode I fracture testing true false true World Conference on Timber Engineering Angleški jezik Ni določen © WORLD CONFERENCE ON TIMBER ENGINEERING 2025 (WCTE 2025) Neznano 2025-08-27 11:40:32 2025-08-27 11:46:13 2025-10-24 03:54:19 0000-00-00 00:00:00 2025 0 0 str. 797-805 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-06-01 624 10.52202/080513-0100 245673987 239752963 https://www.proceedings.com/080513-0100.html 1 e251a6b9-8329-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34623 RAZ_Capuder_Martin_2025.pdf RAZ_Capuder_Martin_2025.pdf 1 2F77CFF7EC921C4FA7D98D3E63C4BC8C e721a28c1a117660ccbc09e3f890ea22fcf3204c3f750cf201e1edfd25f65aee a77f6c1d-832a-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34624 Zavod za gradbeništvo Slovenije 0 0 0
