In this paper, we employed ball milling and ultrasonic irradiation respectively to prepare Unsaturated Polyester Resin/Carbon Black composites. The influences of the two different preparations on the composite properties were studying and comparing. The results showed that the percolation threshold of the composites, which were processed via ball milling or ultrasonic irradiation, were both about 1.8wt％. Tensile strength and elastic modulus of Unsaturated Polyester Resin / Carbon Black composites changed with the carbon black content, when its content was 1 wt％, the two get the maximum. Compared to pure unsaturated polyester resin, composites fabricated by ball milling in the tensile strength and elastic modulus increased by 89％ and 95.8％, while the ultrasonic irradiation mixing enhanced by 23.12％ 38.37％.%采用球磨和超声两种制备工艺分别制备了炭黑填充不饱和树脂复合材料,研究和对比了两种不同工艺对复合材料性能的影响.结果表明,两种制备方法得到的复合材料渗滤阀值均在质量分数1.8%.不饱和树脂/炭黑复合材料的拉伸强度和弹性模量随炭黑含量不同而变化,当其质量分数为1%时,两者出现最大值.相比纯的不饱和树脂,球磨法制备的复合材料的拉伸强度和弹性模量提高了89%和95.8%,而超声法提高了38.37%和23.12%.
