20.500.12556/RUL-128201 Hot incremental forming of biocomposites developed from linen fibres and a thermoplastic matrix Vroče inkrementalno preoblikovanje biokompozitov iz lanenih vlaken in termoplastične matrice The use of biodegradable materials has a growing field of application due to environmental concerns, however, scientific research on incremental forming using biomaterials is scarce. Thus, this study focuses on the single point incremental forming (SPIF) process applied to a composite sheet that combines a biodegradable thermoplastic matrix (Solanyl) reinforced with natural fibres (flax). The influence of the process parameters on the final geometry is determined, evaluating the effect of the following factors: step depth, wall angle and temperature reached during the process. Additionally, a heated aqueous medium is incorporated which facilitates the formability of the composite sheets. This method is especially useful for materials that have poor formability at room temperature. The benefits of using controlled heat include the reduction of formation forces applied to the plate, improved accuracy due to the reduction of elastic recovery, and the manipulation of the samples remarkably close to the glass transition temperatures. Through this experimental study with the variables analysed, a maximum shaping depth of 310 mm is obtained. These results confirm that the single point shaping used with bioplastic materials is possible and has positive outcomes for incremental forming. incremental forming bio-composites hot formability analysis of variance deformation inkrementalo preoblikovanje biokompoziti vroče preoblikovanje analiza variance deformacija true false false Angleški jezik Slovenski jezik Članek v reviji 2021-07-06 11:04:59 2021-07-06 11:05:05 2022-09-07 04:13:38 0000-00-00 00:00:00 2021 0 0 Str.123-132 no. 3 Vol. 67 Mar. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.7.01:539.37 0039-2480 10.5545/sv-jme.2020.6936 69395203 RAZ_Torres_Sandino_2021.pdf RAZ_Torres_Sandino_2021.pdf 1 5502B9069D5860A8229EE27AA47E596D fd31c1b277e9930c1f93e5bb50510c9a2080a41589f9f982becb7cb07d140184 f79f4eed-de39-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=144858 https://www.sv-jme.eu/sl/article/hot-incremental-forming-of-biocomposites-developed-from-flax-fibre-and-a-thermoplastic-matrix/ 1 272409c9-de39-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=144857 Fakulteta za strojništvo Strojniški vestnik 0 0 0
