摘　　要：采用不同粒径的中空玻璃微珠(HGB)填充聚丙烯(PP)。应用热变形温度仪测量了复合材料试样的热变形温度(td)。结果表明,在较低的弯曲载荷下,随着HGB体积分数的增加,试样的td值明显增大;而在较高的弯曲载荷下,试样的td值的提高放缓,甚至有所下降。当载荷及微珠含量一定时,td随着HGB粒径的增加而呈非线性函数形式增大。Polypropylene (PP) was filled by hollow glass beads (HGB) with different size to make composites. The thermal distortion temperature(t_(d))of the samples was measured by means of thermal distortion temperature instrument. The results showed that the value of t_(d) increased obviously with an addition of the HGB volume fraction under lower bending load. However, the value of t_(d) increased gently or somewhat decreased under higher bending load. When loading and HGB content were constant, t_(d) increased nonlinearly with an increase of the HGB diameter.
