20.500.12556/RUL-148938 Recent advancement via experimental investigation of the mechanical characteristics of sisal and juncus fibre-reinforced bio-composites Eksperimentalna raziskava mehanskih lastnosti biokompozitov, ojačenih z vlakni sisala in ločja In this work, the mechanical characteristics of unidirectional bio-composite materials reinforced by two types of natural fibres (sisal andjuncus) were studied in order to develop new materials. The effect of the fibres’ extraction methods and their new assembly techniques on the mechanical properties of the elaborated composites was investigated. This is based on three methods of extracting natural fibres: the first uses water treatment alone over a long period, while the second uses alkaline chemical treatment with a sodium hydroxide solution. The last method uses the burial of plant leaves in moist soil. The obtained fibres are assembled according to techniques, such as monolinear fibres, twisting fibres into rope and braiding fibres into rope. The composite materials are produced manually using a pressure-contact moulding process. The outcomes demonstrated that the resulting compounds’ mechanical properties are significantly impacted by the chemical treatment. The sisal/polyester composites exhibit better mechanical tensile test behaviour than those made with juncus fibres. Moreover, contrary to the results of some other studies, the recently developed techniques of assembling with a chemical treatment process enabled the reduction of the bio-composite’s thickness as well as the cost of its preparation. natural fibre sisal juncus mechanical properties bio-composite naravna vlakna sisal ločje mehanske lastnosti biokompozit poliester natezni preizkus true false true Angleški jezik Slovenski jezik Članek v reviji 2023-09-01 08:46:27 2023-09-01 08:46:29 2025-02-18 12:52:37 0000-00-00 00:00:00 2023 0 0 Str. 339-351 no. 7/8 Vol. 69 Jul./Aug. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.172:677.1/.4 0039-2480 10.5545/sv-jme.2022.456 159374339 Chaouki_..._-_Recent_advancement_via_experimental_investigation_of_the_mechanical_characteristics_of_sisal_and_juncus_fibre-reinforced_bio-composites.pdf Chaouki_..._-_Recent_advancement_via_experimental_investigation_of_the_mechanical_characteristics_of_sisal_and_juncus_fibre-reinforced_bio-composites.pdf 1 3909BA5FB034A34556A5F1C4419E704B c9413f4bc167799ca471643b9a4cc804a23f617a5cab9792e9c96da384a0a734 a7fea881-4893-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173310 https://www.sv-jme.eu/sl/article/elaboration-methods-and-new-fiber-assembly-techniques-effect-on-the-mechanical-properties-of-the-biocomposites-reinforced-by-sisal-and-juncus-fibers/ 1 4a96e73e-4893-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173309 Fakulteta za strojništvo Strojniški vestnik 0 0 0
