Influence of Polyurethane Properties on Mechanical Performances of Magnetorheological Elastomers
Magnetorheological elastomers (MREs) are mainly composed of magnetizable particles and elastic polymer. The polymer matrix plays an important role in mechanical performances of MREs. In this study, the polyurethane (PU), which is synthesized by using toluene diisocyanate (TDI) and poly (propylene glycol) (PPG-220), is selected as a matrix because it has better degradation stability than natural...
متن کاملTemperature Dependent Dynamic Mechanical Properties of Magnetorheological Elastomers: Experiment and Modeling
Magnetorheological elastomers (MREs) are a group of new smart composite materials which are typically comprised of magnetic particles, non-magnetic matrix, and some additives. Their controllable mechanical properties are dependent on many factors, among which temperature is very important yet lack of understanding due to limited studies. In this paper, a series of experimental studies have been...
متن کاملBehavior of magnetorheological elastomers with coated particles
Iron particle coating can improve the behavior of magnetorheological elastomers (MREs) by inhibiting iron particle rusting; however, such a process can change physical properties of MREs such as oxidation resistance, shear modulus, and stiffness change due to an applied magnetic field. In this study, MRE samples are fabricated with regular and polymerized iron particles. To investigate the poss...
متن کاملMagnetorheological elastomers – possibilities and limitations
The mechanical properties of magnetorheological (MR) materials can be changed continuously, rapidly and reversibly by an applied magnetic field. Solid MR materials consist of magnetically polarisable particles, generally iron, in an elastomer matrix. The required iron concentration is high, about 30% by volume. Problems and solutions will be discussed related to MR-technology. Finally long-term...
متن کاملThermoresistance and Giant Magnetoresistance of Magnetorheological Elastomers
A new magnetorheological elastomer composite (MRE) was developed with a resistance which is strongly sensitive both to temperature and pressure. The electrical resistance of this MRE was investigated versus pressure and temperature. The resistance of the composite was recorded versus pressure for seven different values of the temperature. The mechanism of electrical conduction was modeled and a...
