摘要

环氧纳米复合材料的拉伸性能在很大程度上取决于相间性能和纳米颗粒的团聚。为分析环氧/氧化铝纳米复合材料的界面相和团聚效应，采用对数正态分布特征，采用所建立的理论模型对其杨氏模量进行了分析。纳米填料含量越高，团聚作用越明显。团聚和有效杨氏模量随团聚团块尺寸的增加而减小，随着氧化铝纳米填料wt%的增加，其对数正态分布曲线的峰值向更高的值偏移。

Effect of the Interphase and Agglomeration on the Tensile Properties of Epoxy/Alumina Nanocomposites

Tensile properties of the epoxy nanocomposites is very much dependent on the interphase properties and agglomeration of nanoparticles. To analyze the interphase and agglomeration effect, epoxy/alumina nanocomposites were prepared with different content of alumina nanoparticles and its Young’s modulus were analyzed using proposed theoretical model and adopting lognormal distribution characteristics. Agglomeration was more dominant at higher content of nanofiller. Agglomeration and effective Young’s modulus decreased with the increment in the agglomerate size and their lognormal distribution curve’s peak shifted to higher value for higher wt% of alumina nanofiller.
