20.500.12556/DKUM-97570 Numerical investigation of MWCNT effects on elastic properties of PA6/POM blends To ensure the viability of polymer materials, given the properties and limitations of polymers, hybrid materials have been developed that blend the features of all included components. Researchers have not explored the impacts of the length aspect ratio of nanofillers on the mechanical properties of hybrids in great detail previously. Multi-walled carbon nanotubes are a valuable option because they exhibit improved mechanical properties. Using numerical simulation, the impacts of nanofiller content and the size aspect ratio on two base materials—polyamide 6, polyoxymethylene—and their blends, were determined as a function of the volume ratio, the MWCNTs aspect ratio and the base material blend composition. Numerical analysis employed the ANSYS Material Designer. Random samples of chopped-fibre representative volume elements were generated, meshed and analysed by finite element analysis to obtain the Young’s modulus and Poisson’s ratio for each sample. The results showed a generally linear dependence. Rises in both aspect ratio and volume fraction of MWCNTs increased the Young’s modulus up to 46% and decreased the Poisson’s ratio up to 1.6%. The findings suggest that although the impact of the aspect ratio is not as large as that of the volume ratio, longer MWCNTs are preferable. hybrid polymer POM PA6 representative volume element numerical analysis hibridni polimeri reprezentativni elementi prostornine numerična analiza true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/2073-4360/18/5/644 Članek v reviji 2026-03-20 09:47:21 2026-03-20 09:47:22 2026-03-21 03:11:27 0000-00-00 00:00:00 2026 0 0 17 str. iss. 5, [article no.] 644 Vol. 18 March 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2026-01-06 2026-03-01 2026-03-06 519.6:620.1 271363587 10.3390/polym18050644 2073-4360 polymers-18-00644_(1).pdf polymers-18-00644_(1).pdf 1 9B2D3048A828C90AC9552DAB4A64B5A2 a33a740b3c72d2168bd3f501438d3d1622ad7f37345f06293a1faece7434a172 9cf8bee8-243b-11f1-8d16-00155d0001a1 https://dk.um.si/Dokument.php?lang=slv&id=204677 https://www.mdpi.com/2073-4360/18/5/644 0 a5e00bf2-243b-11f1-8d16-00155d0001a1 https://dk.um.si/Dokument.php?lang=slv&id=204678 Fakulteta za strojništvo 0 0 0
