20.500.12556/DiRROS-15876 Effects of selected printing parameters on the fire properties of 3D-printed neat polylactic acid (PLA) and wood/PLA composites The effects of selected printing parameters on the fire properties of additively produced composites from neat polylactic acid (PLA) and wood/PLA filaments were investigated. The reaction to fire of the 3D-printed specimens was tested according to the ISO 5660-1 cone calorimeter test method. The results showed that the properties of the specimens when exposed to fire were significantly affected by the incorporation of wood flour into the PLA filament. It was also interesting that PLA specimens had much better reactions to fire than the wood/PLA specimens. Time to ignition was found to be much longer in the 3D-printed PLA specimens. Although the maximal heat release rate was a little higher in the PLA than the wood/PLA specimens, the duration of HRR was longer for the wood/PLA specimens. The initial mass of the specimens was smaller in the wood/PLA composites, but during the radiant heat exposure the mass typically decreased slower than in the PLA specimens. reaction to fire wood polylactic acid (PLA) filament 3D printer biocomposite protipožarna odpornost les polilaktična kislina (PLA) filament 3D tiskalnik biokompozit true false true Scrivener Angleški jezik Slovenski jezik © Authors 2021 Neznano 2022-12-02 09:10:07 2023-07-17 08:17:47 2023-07-18 03:35:19 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Opis vira z dne 25. 5. 2021; str. 1883-1895 no. 11 Vol. 9 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-05-25 620.1/.2 2164-6341 10.32604/jrm.2021.016128 64464899 https://www.techscience.com/jrm/online/detail/18181 Open access 1 5c9a4dac-7210-11ed-a69a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20993 RAZ_Knez_Natasa_2021.pdf RAZ_Knez_Natasa_2021.pdf 1 258E48A6CB701E80DDAB62617966C86D 162ea34340ceb7fff50b8fa4d76052e5075280a534b12507fa0013ce7a115e89 4902a740-9b25-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21454 Zavod za gradbeništvo Slovenije 0 0 0
