摘　　要：研究了纳米TiO2含量对纳米TiO2/环氧复合材料弯曲性能和拉伸性能的影响。结果表明,超声作用可以使纳米TiO2均匀分散于树脂体系中;环氧树脂中添加纳米TiO2可以同时增强增韧环氧树脂,当纳米TiO2含量为3%时,纳米TiO2/环氧的弯曲强度和拉伸强度比未添加纳米TiO2时分别提高了72%和65%。This paper discusses the effect of the content of nano-TiO_2 on the bend strength and tensile properties of nano-TiO_2 / epoxy composites.The experiment results show that the ultrasonic can make nano-TiO_2 disperse evenly in the resin system and the nano-TiO_2 can also improve the mechanical property of the epoxy composites.When the content of nano-TiO_2 is 3%,the bending and tensile strength of the TiO_2/epoxy composites can be 72% and 65% higher than that without nano-TiO_2 particles.
