【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。更多还原

【Abstract】 It measured the effective thermal conductivity(K_eff) of hollow glass bead（HGB） filled-polypropylene（PP） composites by means of a thermal conductivity instrument.The results showed that theK_eff decreases linearly with the increasing addition of the volume fraction（_f） of the HGB except some individual data points.TheK_eff decreases slightly with the increase of the particle diameter when _f is kept constant.更多还原
