Temperature-Dependent Viscoelastic Response of Magnetorheological Grease with Varying Particle ShapesBy Nur Adilah Adanan, Abdul Yasser Abd Fatah, Nur Azmah Nordin, Saiful Amri Mazlan, Siti Maisarah Ahmad Tarmizi, Rehnupreya Hentry Viension, Khairul Anwar Abdul Kadir
Abstract: This study examines the effect of temperatures on the magnetic and rheological properties of magnetorheological greases (MRGs) comprised of different particle shapes, under oscillatory shear mode test. Two samples were prepared with 70 wt.% flake-shaped electrolytic iron particles (EIP) and spherical carbonyl iron particles (CIP) which dispersed in 30 wt.% lithium-based grease, separately. Respective to magnetic properties test, the vibrating sample magnetometry (VSM) revealed that MRG-EIP exhibited 11.4% higher magnetic …

Influence of Carbonyl Iron Particle Loading on the Dimensional and Rheological Properties of 4D-Printed TPU-Based Magnetorheological ElastomersBy Ahmad Fitri Sukarman, Norasyidah Mohd Noh, Nurulhuda Khalid, Saiful Amri Mazlan, Mohd Aidy Faizal Johari, Muhammad Farhan Mohamad Fitri, Shahir Mohd Yusuf, Nur Azmah Nordin, Abdul Yasser Abd Fatah
Abstract: The advancement of 4D printing technologies has created new opportunities for fabricating smart materials with tunable properties, including magnetorheological elastomers (MREs). This study investigates the fabrication and characterization of thermoplastic polyurethane (TPU)-based MREs with varying carbonyl iron particle (CIP) loadings (10–50 wt.%) using the fused filament fabrication (FFF) method. MRE filaments were produced through a solvent-assisted mixing and extrusion process, ensuring consistent diameters within 1.75 ± 0.10 mm. Test specimens …
