摘 要: 应用导热系数测量仪,测量了中空玻璃微珠(HGB)填充聚丙烯复合材料的等效导热系数(Keff)。结果表明:除个别点外,随着HGB体积分数(φf)增加,Keff呈线性函数形式减小;当φf相同时,Keff随着HGB粒径的增加而有所下降。 It measured the effective thermal conductivity (Keff) of hollow glass bead (HGB) filled-polypropylene (PP) composites by means of a thermal conductivity instrument. The results showed that the Keff decreases linearly with the increasing addition of the volume fraction (Фf) of the HGB except some individual data points. The Keff decreases slightly with the increase of the particle diameter when Фf is kept constant.
