| 摘 要： | 本文研究了使用溶剂法、密炼机和开炼机混炼碳纤维填充ABS树脂复合材料的导电性能,得到了纤维填充量与复合材料电阻率的关系,对其导电机理进行了分析.通过比较,发现纤维长径比是决定复合材料导电性能的重要因素,其它如纤维在基体中的分布也对复合材料导电性能有影响.最后对复合材料的屏蔽性能进行了理论计算.

| Abstract: | The electrical properties of ABS resin filled with carbon fibers,mixed by solvent, two-roll mill and brabender were studied in this paper.The relationship between the fiber content and the resistivity of the composites was obtained and its conductive mechanism was analyzed.By comparing the results it was shown that the aspect ratio of carbon fibers plays an important role in the resistivity of the composites.Other factors such as fiber distribution in the composites also have some effects on it.Shielding effects of these composites were obtained by theoretical calculation. |

| Keywords: | carbon fibers-filled composites aspect ratio electrical properties shielding effects |
