摘要
以环氧树脂(EP)为基体、石墨烯(GNP)和多壁碳纳米管(MWCNT)为增强材料制备了EP/GNP/MWCNT纳米复合材料,通过拉伸试验考察了GNP与MWCNT的混合比例对复合材料力学性能的影响。结果表明:当GNP与MWCNT的总添加量为0.3%、混合比例为50:50时,EP/GNP/MWCNT纳米复合材料的综合力学性能达到最佳,此时复合材料的弹性模量、拉伸屈服强度、拉伸断裂强度、破坏应变等均达到或接近最大值。
The epoxy resin/grapheme/multi-walled carbon nanotubes(EP/GNP/MWCNT) nanocomposites were prepared with EP as matrix, GNP and MWCNT as reinforcing materials. The effects of mixing ratio of GNP and MWCNT on mechanical properties of the composites were investigated by extension tests. The results show that when the total amount and mixing ratio of GNP and MWCNT are 0.3% and 50:50 respectively, the EP/GNP/MWCNT nanocomposite has the optimum comprehensive mechanical properties, and the elastic modulus, yield strength, fracture strength and failure strain can reach or approach to the maximum values.
