Effects of Sub-Zero Temperatures on the Viscoelastic Properties of Magnetorheological ElastomerBy Suziyani Zin, Nur Azmah Nordin, Saiful Amri Mazlan, Mohd Aidy Faizal Johari, Abdul Yasser Abd Fatah, Rehnupreya Hentry Viension, Nur Hairunnisa Kamarudin
Abstract: Magnetorheological elastomers (MREs) are smart materials capable of tuneable stiffness and damping under applied magnetic fields. This renders the material as a promising candidate for adaptive vibration control and semi-active engineering applications. While their behaviour at elevated temperatures has been widely explored, limited attention has been given to their performance under sub-zero conditions, which are critical for cold-environment applications. As this has become an important concern, the study investigates the …

Material-Level Degradation of Magnetorheological Fluids Under Long-Term Cyclic ShearBy Dewi Utami, Saiful Amri Mazlan, Nur Azmah Nordin, Mohd Aidy Faizal Johari, Ubaidilla
Abstract: The long-term functional stability of magnetorheological fluids (MRF) remains a key limitation for their reliable use in adaptive systems and continuously operated magnetorheological devices. In this study, the intrinsic evolution of rheological properties in a commercial MRF (MRC-C1L) is systematically examined under prolonged cyclic loading, with the aim of isolating material-level degradation mechanisms independent of device-related effects. The fluid was subjected to 120,000 low-strain oscillatory shear cycles under a constant …

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 …

Effect of Carbonyl Iron Particle Concentration on The Printability and Stiffness of Magnetorheological Elastomer FilamentsBy Khairul Anwar Abdul Kadir, Nor Fairuz Hayati Amir, Nur Raihana Sukri, Wan Nur Atiqah Mior Hamdan, Saiful Amri Mazlan, Nur Azmah Nordin, Mohd Aidy Faizal Johari
Abstract: Magnetorheological elastomer (MRE) are increasingly valued for their field-responsive mechanical properties, making them ideal for adaptive components in automotive, aerospace, and vibration control systems. However, conventional mould-based fabrication methods limit design flexibility, produce excess material waste, and are unsuitable for complex or customized geometries caused challenges that have hindered broader industrial adoption. Although 3D printing offers a compelling alternative, research on printable MRE filaments remains limited, particularly regarding how carbonyl …
