20.500.12556/RUL-122938 Rheological behaviour of highly filled materials for injection moulding and additive manufacturing effect of particle material and loading Within this paper, we are dealing with a mixture of thermoplastic polymer that is filled with inorganic fillers at high concentrations up to 60 vol.%. A high number of particles in the compound can substantially change the rheological behaviour of the composite and can lead to problems during processing in the molten state. The rheological behaviour of highly filled materials is complex and influenced by many interrelated factors. In the present investigation, we considered four different spherical materials: steel, aluminium alloy, titanium alloy and glass. Particles with similar particle size distribution were mixed with a binder system at different filling grades (30–60 vol.%). We showed that the rheological behaviour of highly filled materials is significantly dependent on the chemical interactions between the filler and matrix material. Moreover, it was shown that the changes of the particle shape and size during processing lead to unexpected rheological behaviour of composite materials as it was observed in the composites filled with glass beads that broke at high contents during processing. highly filled materials polypropylene binder binder-filler interaction particle-particle interaction shear rheology fused filament fabrication ATR-FTIR XPS materiali z visokim deležem polnitve vezivni sistem polipropilen polipropilensko vezivo interakcija veziva in polnila ciljno nanašanje slojev true false true Angleški jezik Slovenski jezik Članek v reviji 2020-12-17 09:56:57 2020-12-17 09:56:58 2022-09-03 04:10:26 0000-00-00 00:00:00 2020 0 0 23 str. iss. 22, art. 7993 Vol. 10 11 Nov. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 678.742.3 2076-3417 10.3390/app10227993 38860291 RAZ_Bek_Marko_2020.pdf RAZ_Bek_Marko_2020.pdf 1 515D2CF62A06C40D1597F5E179323CEB b1a80caf68a463b5da50ff9b0ec0f81b3ff79b5c74f6fef27b0d688d40f46ca5 ea79eb9e-7ddc-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153242 https://www.mdpi.com/2076-3417/10/22/7993 0 77de4172-7ddc-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153240 Fakulteta za strojništvo 0 0 0
