Determination of Distribution Patterns of Fillers in Composites by Micromorphological Parameters

抄録

The nonuniform distribution of fillers in a composite is studied both experimentally and analytically. A set of three parameters are proposed to characterize the distribution patterns of fillers in a particulate composite: homogeneity distribution parameterξ, anisotropy parameter of the first kindηand that of the second kindφ. These parameters are used to examine the distribution patterns of l0 % and 20 % SiC particulate/6061 Al (SiCp/Al) composite. This led us to believe application of the three parameters to actual composites provides useful information about the micromorphology of particulates. The distribution pattern of SiCp/Al composite is also examined from the viewpoint of fractal analysis, resulting in some correlation between the fractal analysis and one of the proposed three parameters.
