氧化锌晶须/环氧树脂复合材料自由振动实验研究

EXPERIMENTAL STUDY ON ZINC OXIDE WHISKER /EPOXY RESIN COMPOSITE MATERIAL'S FREE VIBRATION

利用浇铸成型工艺 ,将氧化锌晶须 (ZnOm)填料按 0、5 %、10 %、15 %、2 0 %的配比加入到环氧树脂中 ,制得高聚物阻尼材料 .通过自由振动实验表明 :ZnOm 晶须的加入量和阻尼系数成线性关系 ,随着ZnOm晶须的加入 ,复合材料的阻尼系数大大增加 .该文对ZnOm 晶须的复合材料在减振领域内的应用提供了实验依据 .

Blending Zinc oxide in different proportion (0、5%、10%、15%、20%)with epoxy resin by casting method,we can obtain polymeric damping material.The free vibration experiment about damping material suggests that the quantity of Zinc oxide has a linear relationship with the coefficient of damping. With the increase of Zinc oxide,the coefficient of damping is greatly improved.This article gives an experimental base in the damping field.
