| 摘 要： | 采用扫描电镜(SEM)、透射电镜(TEM)、X射线光电子能谱(XPS)仪和NOL环等方法,对纳米TiO2在环氧树脂(EP)体系中的分散效果、炭纤维表面状态及复合材料性能等进行了系统研究。结果表明:采用高速剪切与超声波复合分散工艺,可以将纳米TiO2均匀分散在EP体系中;当w(纳米TiO2)=2%～3%时,纳米TiO2/EP浇铸体的最大拉伸强度为112 MPa、最大弯曲强度为175 MPa和最大Tg为141.9℃;纳米TiO2可以有效改善炭纤维与EP基体间的界面结合力,形成较理想的界面相,制成的复合材料具有优异的力学性能,其拉伸强度、拉伸模量和剪切强度分别为2.15 GPa、117 GPa和49.9 MPa。 |

| Abstract: | The dispersion effect of nano-TiO2 in epoxy resin(EP) system,the surface state of carbon fiber,and the performance of composites were systematically investigated by scanning electron microscope(SEM),transmis-sion electron microscope(TEM),X-ray photoelectron spectroscopy(XPS),NOL ring and other methods.The results showed that the nano-TiO2 could be evenly dispersed in the EP systems by composite dispersing technology between high-speed shearing and ultrasonic.The maximal tensile strength,bend strength and gl... |
