20.500.12556/RUL-153131 Does a compatibilizer enhance the properties of carbon fiber-reinforced composites? We have evaluated the effectiveness of compatibilizers in blends and composites produced using a solvent manufacturing process. The compatibilizers were two different types of polyethylene (linear low-density and high-density) grafted with maleic anhydride (MAH) and a highly functionalized, epoxy-based compatibilizer with the trade name Joncryl. The selected material combinations were an ultra-high-molecular-weight polyethylene (UHMWPE) with MAH-based materials as compatibilizers and a polyphenylene sulfide plus polytetrafluoroethylene (PPS-PTFE) polymer blend with an epoxy-based compatibilizer. The findings revealed that while the compatibilizers consistently enhanced the properties, such as the impact strength and hardness of PPS-based compositions, their utility is constrained to less complex compositions, such as fibrous-reinforced PPS or PPS-PTFE polymer blends. For fibrous-reinforced PPS-PTFE composites, the improvement in performance does not justify the presence of compatibilizers. In contrast, for UHMWPE compositions, compatibilizers demonstrated negligible or even detrimental effects, particularly in reinforced UHMWPE. Overall, the epoxy-based compatibilizer Joncryl stands out as the only effective option for enhancing mechanical performance. Thermal and chemical characterization indicated that the compatibilizers function as chain extenders and enhance the fiber–matrix interface in PPS-based compositions, while they remain inactive in UHMWPE-based compositions. Ultimately, the incompatibility of the compatibilizers with certain aspects of the manufacturing method and the inconsistent integration with the polymer are the main reasons for their ineffectiveness in UHMWPE compositions. compatibilizers carbon fiber polymer composites UHMWPE PTFE PPS kompatibilizatorji ogljikova vlakna polimerni kompoziti true false true Angleški jezik Slovenski jezik Članek v reviji 2023-12-19 08:08:59 2023-12-19 08:09:04 2024-12-04 14:11:11 0000-00-00 00:00:00 2023 0 0 18 str. iss. 23, art. 4608 Vol. 15 Dec. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 678 2073-4360 10.3390/polym15234608 178027779 Gangwani,_Kalin,_Emami-Does_a_compatibilizer_enhance_the_properties_of_carbon_fiber-reinforced_composites.pdf Gangwani,_Kalin,_Emami-Does_a_compatibilizer_enhance_the_properties_of_carbon_fiber-reinforced_composites.pdf 1 131567CF06DF396956C8E68A88062C3B 9b0799c0b7e9c7fff1826d7ac7ee5bfc9f15629f0d3ab1235dc1d7d46350634d b8b76251-9e3d-11ee-805c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179032 https://www.mdpi.com/2073-4360/15/23/4608 1 7ec804a3-9e3d-11ee-805c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179031 Fakulteta za strojništvo 0 0 0
