20.500.12556/RUL-145152 Fatigue and wear performance of autoclave-processed and vacuum-infused carbon fibre reinforced polymer gears This study focuses on investigating the fatigue and wear behaviour of carbon fibre reinforced polymer (CFRP) gears, which have shown promising potential as lightweight and high-performance alternatives to conventional gears. The gears were fabricated via an autoclave process using an 8-layer composite made of T300 plain weave carbon fabric and ET445 resin and were tested in pair with a 42CrMo4 steel pinion and under nominal tooth bending stress ranging from 60 to 150 MPa. In-situ temperature monitoring was performed, using an infrared camera, and wear rates were regularly assessed. The result of the wear test indicates adhesive wear and three-body abrasion wear mechanisms between the CFRP gears and the steel counterpart. A finite element analysis was performed to examine the in-mesh contact and root stress behaviour of both new and worn gears at various loads and a specified running time. The results point to a substantial divergence from ideal meshing and stress conditions as the wear level is increased. The fatigue results indicated that the CFRP gears exhibited superior performance compared to conventional plastic and composite short-fibrous polymer gears. The described composite gear material was additionally compared with two other composite configurations, including an autoclave-cured T700S plain weave prepreg with DT120 toughened resin and a vacuum-impregnated T300 spread plain weave carbon fabric with LG 900 UV resin. The study found that the use of the T700S-DT120 resulted in additional improvements. carbon fibre reinforced polymer gears fatigue wear finite element analysis autoclave vacuum infusion kompoziti iz ogljikovih vlaken zobniki utrujanje obraba analiza po metodi končnih elementov avtoklav vakuumska infuzija true false true Angleški jezik Slovenski jezik Članek v reviji 2023-04-11 09:29:25 2023-04-11 09:29:30 2025-02-24 08:54:03 0000-00-00 00:00:00 2023 0 0 24 str. iss. 7, art. 1767 Vol. 15 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.83:620.178.3 2073-4360 10.3390/polym15071767 148318211 Bergant_..._-_Fatigue_and_wear_performance_of_autoclave-processed_and_vacuum-infused_carbon_fibre_reinforced_polymer_gears.pdf Bergant_..._-_Fatigue_and_wear_performance_of_autoclave-processed_and_vacuum-infused_carbon_fibre_reinforced_polymer_gears.pdf 1 81982D4E99EC7BE22B6B7F1CF1BF1C25 89558666d455cb77c574bdc115e9402fd403675052fbb03bf942b081ceb31530 13d8f826-d83b-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167824 https://www.mdpi.com/2073-4360/15/7/1767 1 74df7cc7-d83a-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167823 Fakulteta za strojništvo 0 0 0
