不同应变率下多壁碳纳米管/天然橡胶复合材料的抗冲击性能研究

Study on Impact Resistance of MWNTs/NR Composites under Different Strain Rate

研究多壁碳纳米管(MWNTs)/天然橡胶复合材料在不同应变率下的抗冲击性能。结果表明:随着MWNTs用量的增大,复合材料的压缩弹性模量和吸能率增大,抗冲击性能提高;在MWNTs的用量相同时,复合材料的吸能率随着应变率的增大而增大,且增幅随着MWNTs用量的增大而变大。

The impact resistance of MWNTs/NR composite under different strain rate was investigated. The results showed that,as the addition level of MWNTs increased,the compressive elastic modulus and the energy absorbability of the composites increased,and the impact resistance was improved. When the addition level of MWNTs was the same,the energy absorbability of composites increased with the strain rate increasing,and the increase was greater as the addition level of MWNTs became greater.
