要約(日本語): Experimental results on the characteristics of viscosity of unimodal and bimodal alumina/epoxy mixtures are shown, and then discussed and estimated based on theoretical considerations. Spherical alumina particles with 35 and 80 micrometer in diameter were used. For unimodal mixture, viscosity of the mixture increased significantly with the volumetric packing fraction of particle, and Brinkman equation can be applied to estimate viscosity from it. For bimodal mixture, viscosity depends not only on volumetric packing fraction , but also on the volume ratio of coarse particles to all particles. Farris method, also utilizing the estimated unimodal viscosity by Brinkman equation, is applicable to estimate viscosity of the bimodal mixture at lower packing fraction, while for higher packing fraction, we propose a modification of the procedure, and achieved reasonably better estimation.
