Tension test data and blast erosion test data are presented for the eoxy composite systems in which the volume fractions of dispersion were changed. The dispersed materials were sus304, Al and Al_2O_3 powders and their average particle sizes were 44〜68 μm. The results showed that the tensile strength of epoxy compostes could be slightly increased by choosing a proper volume fraction of SUS304 or Al powders. However, the tensile strengh decreased ith increasing the volume fraction of sintered Al_2O_3 powder. Also a profound effect was found on the resistance to blast erosion of the composites, depending on the volume fraction of the dispersion used. These experimental results indicated a good correlation between the resistance to blast erosion of the composites and the tensile strength.
