Abstract
Magnetic damping composite was prepared by mechanical blending method. As acrylonitrile butadiene rubber was matrix, strontium ferrite magnetic powder was function phase. The vibrating sample magnetometer (VSM) test shows that the magnetic properties of the magnetic rubber composite are related with the content of the magnetic powder and unrelated with rubber matrix. The dynamic mechanical analysis (DMA) and TA method compare show that the damping properties of the composite are improved with adding the strontium ferrite magnetic particle, but the damping properties of composite are best after magnetizing the sample, but the damping properties of the composites decreased with increasing the content of the magnetic powder. The damping properties of the composites at the test frequency 30HZ and 50HZ are higher than 1HZ.
