| 中文摘要: |
| 采用超声辐照处理多壁碳纳米管增强环氧树脂复合材料,分析了超声辐照条件对复合材料的黏度、力学性能及拉伸断口显微形貌的影响。结果表明:温度一定时,多壁碳纳米管增强环氧树脂体系的黏度随超声辐照时间的延长而逐渐降低;超声辐照时间为5min时,环氧树脂的拉伸强度、弯曲强度、拉伸剪切强度达到最大值,较处理前分别提高了37%,167%和86%;经超声辐照后,拉伸断口形貌显示出更多的韧性断裂特征。 |

| The multi-walls carbon nanotubes reinforced epoxy resin was treated with ultrasonic irradiation. The effects of ultrasonic irradiation on the viscosity, mechanical properties and fracture morphologies of composites were investigated. The results show that at the same temperatures, the viscosity of multi-walls carbon nanotubes reinforced epoxy resin gradually decreases with the increasing of ultrasonic irradiation time; When the ultrasonic irradiation time is 5 min, the tensile strength, flexural strength and tensile shear strength of epoxy resin reach the highest value, which were increased respectively by 37%,167% and 86%; Ultrasonic irradiation can make the tensile fracture morphology show more ductile fracture characteristics. |
