制备了不同尺寸Al2O3颗粒填充聚砜（PSF）基聚合物复合材料，并对复合材料的拉伸性能和冲击性能进行了测试。结果显示，Al2O3填充颗粒越小，复合材料的拉伸强度越强；纳米复合材料与微米复合材料的拉伸强度随着填充量增加表现出不同的变化趋势。PSF基复合材料的冲击强度随填充量的增加迅速下降，这主要是因为颗粒填料限制了基体的塑性变形能力；填料颗粒的尺寸对冲击性能也有影响。

The polysulfone composites filled with Al2O3 particles of different size are prepared. Tensile strength and impact strength of the composites are evalu-ated. The smaller the particle size, the higher the tensile strength for the composites is tested. The composites with nano-sized and micro-sized particles show different trends in tensile strength with particle contents. The impact strength of polysulfone composites reduces with the in-creasing of the loading level, because the particle ifller re-stricts the plastic deformation ability of matrix. However, the particle size has also effect on the impact strength.
