根据路易斯和尼尔森的混合定律及其颗粒堆积模型，我们讨论了两种尺寸的二氧化硅颗粒的组成对环氧复合材料热粘弹性能的影响。含有两种尺寸的球形二氧化硅颗粒的不同组成比 Phi(SP) 的环氧复合材料。以固定体积分数(V-P＝0.30)制备0.24和1.56μm。使用路易斯和尼尔森定律以及 Ouchiyania 和 Tanaka 模型的最大颗粒堆积分数 phi(max)，研究了在前 123 至 53.5 K 测量的这些复合材料和纯环氧树脂的热粘弹性能。我们的结果表明，热粘弹性受到低于玻璃化转变温度 T 的最大填充分数的影响。以及基体树脂在 T > T-g 时的迁移率。 (c) 2006 Acta Materialia Inc. 由 Elsevier Ltd 出版。保留所有权利。
We discuss the effect of compositions of two sizes of silica particles on the thermo-viscoelastic properties of epoxy composites according to Lewis and Nielsen's mixture law and its particle packing model. Epoxy composites containing varied composition ratios Phi(SP) of two sizes of spherical silica particles. 0.24 and 1.56 mu m were prepared at it fixed volume fraction (V-P = 0.30). The thermo-viscoelastic properties of these composites and neat epoxy resin measured front 123, to 53,5 K were investigated using Lewis and Nielsen's law with the maximum packing fraction of particles phi(max) of Ouchiyania and Tanaka's model. Our results revealed that thermo-viscoelasticity was affected by the maximum packing fraction below the glass transition temperature T,. and the mobility of matrix resin at T > T-g.
