为了提高环氧树脂的力学性能,采用一步合成法制备得到氧化石墨烯(GO)-SiO2(GO-SiO2)杂化材料,利用扫描电子显微镜(SEM)对杂化材料的形貌进行表征,成功制得了具有三维结构的GO-SiO2杂化材料;将GO、SiO2颗粒和GO-SiO2以相同的含量(质量分数均为0.1％)添加到环氧树脂中制备复合材料,利用万能强力仪测试复合材料的拉伸性能,比较3种填料对树脂基复合材料拉伸性能的影响;再分别将质量分数为0.1％、0.3％和0.5％的GO-SiO2添加到环氧树脂中制备GO-SiO2/环氧树脂复合材料,比较不同质量分数的GO-SiO2对树脂基复合材料拉伸性能的影响;利用SEM对拉伸样条的断截面进行扫描测试,分析了不同种类和不同比例的填料对树脂基复合材料的增强增韧效果,并分析其增强增韧机制.结果表明:GO-SiO2的增强增韧效果明显优于GO和SiO2颗粒,当GO-SiO2的添加质量分数为0.3％时,其增强增韧效果最佳.
