纳米碳纤维复合材料的电阻-应变传感性能研究

Study on carbon nanofibers composite material＇s resistance-strain sensor property

制备了不同含量的纳米碳纤维，环氧树脂复合材料试样，采用三点弯曲法测试了复合材料的电阻．应变行为．结果表明，纳米碳纤维，环氧树脂复合材料具有良好的电阻．应变行为，且当纳米碳纤维含量为4％～6％（质量分数）时，电阻．应变呈线性变化，复合材料的传感性能最为优异．

In this paper, a series of carbon nanofibers/epoxy resin composite samples were fabricated, and the resistance-strain behavior was researched, as the result, the carbon nanofibers composite showed superior sensor property. Further more, the date indicated that the composites＇ sensor property were better than else when the content of carbon nanofibers in epoxy resin was 4%-6（wt%）.
