20.500.12556/DKUM-92253 In-plane deformation behavior and the open area of rotating squares in an auxetic compound fabric A conventional compound fabric was used to develop a modern, multifunctional material with an auxetic behaviour and a tailored open area for particle filtration. Such material was produced using traditional textile technology and laser cutting, to induce a rotating squares unit geometry. The behaviour was investigated of three different rotating unit cell sizes. The laser slit thickness and the length of the hinges were equal for all three-unit cells. The tensile properties, Poisson’s ratio and auxetic behaviour of the tested samples were investigated, especially the influence of longitudinal displacement on the fabric’s open area and the filtered particle sizes (average and maximum). Results show that the developed compound fabric possesses an average negative Poisson’s ratio of up to −1, depending on the applied auxetic geometry. The larger rotating cell size samples offer a higher average negative Poisson’s ratio and a higher breaking strength due to the induced slits. The findings highlight the usefulness of patterned cuts in conventional textile materials to develop advanced auxetic textile materials with tailored geometrical and mechanical properties. compound textile material auxetic structure open area filtration mechanical properties Poisson’s ratio sestavljeni tekstilni materiali avksetične strukture odprta površina filtracija mehanske lastnosti Poissonovo razmerje true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/polymers © 2022 by the authors Članek v reviji 2025-03-25 15:01:42 2025-03-25 15:01:43 2025-03-26 03:07:48 0000-00-00 00:00:00 2022 0 0 14 str. iss. 3 (571) Vol. 14 Jan. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-01-04 2022-01-28 2022-01-31 677.017:539.2 96436739 10.3390/polym14030571 2073-4360 polymers-14-00571.pdf polymers-14-00571.pdf 1 C28695ADBD287C7347007F92653F1062 65128d48742c344b724032d8ccc76a5f550d459403f15a9914745eb30153147d f798b1fe-0981-11f0-853e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189643 https://www.mdpi.com/2073-4360/14/3/571 0 fbef7e0b-0981-11f0-853e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189644 Fakulteta za strojništvo 0 0 0
