20.500.12556/DiRROS-23426 Dynamic mechanical analysis of fpu bonded beech wood at various temperatures This study investigates the dynamic mechanical properties of flexible polyurethane (FPU) adhesives bonded to European beech wood (Fagus sylvatica L.) using Dynamic Mechanical Analysis (DMA) over a range of temperatures and frequencies. Samples included clear beech wood and three-layered composite (beech:FPU:beech). DMA tests were performed using a three-point bending setup at 1 Hz and 10 Hz in the temperature range from -120°C to 140°C. The results demonstrated high thermal stability and strong bonding performance of FPU adhesives on beech wood. Frequency-dependent responses varied among FPU types but resembled the behavior of solid wood at lower temperatures. This confirms the suitability of DMA for evaluating adhesive-wood composite behavior under dynamic conditions. The combination of FPU adhesives and beech wood showed potential for thermally stable and energy-dissipating bonded assemblies. dynamic mechanical analysis FPU beech wood true false true World Conference on Timber Engineering Angleški jezik Ni določen © WORLD CONFERENCE ON TIMBER ENGINEERING 2025 (WCTE 2025) Neznano 2025-08-27 11:50:30 2025-08-27 11:54:58 2025-10-24 03:54:19 0000-00-00 00:00:00 2025 0 0 str. 1620-1625 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-06-01 624 10.52202/080513-0197 245760003 239752963 https://www.proceedings.com/080513-0197.html 1 46072bb8-832b-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34625 RAZ_Capuder_Martin_2025.pdf RAZ_Capuder_Martin_2025.pdf 1 7CE9F304DB61E08E353865E2F5C75E98 84e69d615863d0b0428e300ec3d1c554a0c570b3e76ea8aa97a05fde183f50bc dd5e4b38-832b-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34626 Zavod za gradbeništvo Slovenije 0 0 0
