摘要

本文研究了以铁为填料分布的磁流变弹性体(MREs)复合材料的力学性能。以50 ~ 150 μm的不规则形状铁颗粒为基体,制备了MREs复合材料。以催化剂比为1:1,填料含量为30 Vol %的ZA22为粘结剂。在复合材料中使用硅油作为添加剂粘结剂,将填料掺入弹性体基体中。采用开路电磁线圈作为磁通强度的磁路。通过诱导不同强度的磁场,观察复合材料的力学性能。由于复合材料在压缩过程中能量的耗散,在MRE样品中观察到磁滞损失。在0.3特斯拉恒定的变强磁场下,MRE的工程强度得到了提高。

Improved mechanical properties of magneto rheological elastomeric composite with isotropic iron filler distribution

In this work, mechanical property of magneto rheological elastomeric (MREs) composite is investigated using iron as filler distribution. The MREs composite were fabricated using irregular shaped iron particles with size range varies from 50 -150 μm in matrix of elastomeric polymer. The matrix such as ZA22 was considered with 1:1 catalyst ratio as the binder with 30 Vol % of filler content. The fillers were incorporated within the matrix of elastomer using silicon oil as additive binder in the composite. The open circuit solenoid coil was designed as the magnetic circuit for magnetic flux intensity. Various magnetic field intensities were induced to observe the mechanical properties of the MREs composites. Hysteresis loss was observed in MRE samples due to dissipation of energy during compression of the composite material. Improved engineering strength of the MRE is observed on varying magnetic field of intensity and constant at 0.3 Tesla.
