Tension test data and blast erosion test data are presented for the epoxy composite systems in which the volume fractions of dispersion were changed. The dispersed materials were SUS304, Al and Al2O3 powders and their average particle sizes were 44-68μm. The results showed that the tensile strength of epoxy composites could be slightly increased by choosing a proper volume fraction of SUS304 or Al powders. However, the tensile strength decreased with increasing the volume fraction of sintered Al2O3 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.
