摘要:
采用混炼模压极化工艺制备了压电陶瓷/碳黑/丁基橡胶聚合物基压电阻尼复合材料,研究了压电陶瓷和碳黑用量、外力及作用频率等因素对复合材料阻尼性能的影响.结果表明,当压电陶瓷体积分数为50%、碳黑质量分数为5%时复合材料的阻尼因子tanδ峰值达到最高,有效阻尼温域最宽;复合材料的阻尼性能随着外力的增加而增强;当外力作用频率f接近或等于橡胶分子运动单元松弛时间的倒数1/τ时,复合材料的损耗模量E″和阻尼因子tanδ均出现最大值
Abstract:
Piezoelectric ceramic/carbon black/isobutylisoprene rubber damping composite is prepared by the process of mixingcompression moldingpolarization. The relationship between the damping characteristics and the factors including the content of piezoelectric ceramic and carbon black, stress and frequency has been researched. The results show that the damping coefficient value tanδ achieve a peak value and the available temperature area of damping is the widest when the PMN content is 50 vol% and the CB content is 5 wt%, and the damping properties of composite increased with the increasing of the stress. When the frequency is equal to the reciprocal of relaxation time(1/τ) of rubber molecule sport unit, the E″ and tanδ can achieve a peak value
