20.500.12556/RUL-137942 Long-term creep compliance of wood polymer composites using untreated wood fibers as a filler in recycled and neat polypropylene matrix Neat (NPP) and recycled (RPP) polypropylene matrix materials were used to prepare wood–polymer composites with untreated wood fibers up to 40 wt.%. Long-term creep properties obtained through the time-temperature superposition showed superior creep resistance of composites with NPP matrix. In part, this is attributed to their higher crystallinity and better interfacial adhesion caused by the formation of a transcrystalline layer. This difference resulted in up to 25% creep compliance reduction of composites with NPP matrix compared to composites with recycled (RPP) polypropylene matrix, which does not form a transcrystalline layer between the fibers and polymer matrix. Despite the overall inferior creep performance of composites with RPP matrix, from the 20 wt.% on, the creep compliance is comparable and even surpasses the creep performance of unfilled NPP matrix and can be a promising way to promote sustainability. wood–polymer composites creep durability wood recycling lesno-polimerni kompoziti lezenje vzdržljivost les recikliranje true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-06 13:40:42 2022-07-06 13:40:43 2023-05-17 03:56:38 0000-00-00 00:00:00 2022 0 0 19 str. iss. 13, art. 2539 Vol. 14 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677.017:631.571 2073-4360 10.3390/polym14132539 113069315 Bek_..._Long-term_creep_compliance_of_wood_polymer_....pdf Bek_..._Long-term_creep_compliance_of_wood_polymer_....pdf 1 70D62B7A5D8CBC2E31F91E5D93F90C52 39f57489a4b6226cb5946154fcecaa2421ceea8b4b062823729a9e3c1ba3a1b6 42557865-01cd-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158380 https://www.mdpi.com/2073-4360/14/13/2539 0 26e586f9-fd22-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158072 Fakulteta za strojništvo 0 0 0
