| Abstract | ||
| In this research, binary and ternary polymer blends were prepared by hand lay-up method with different weight ratios. The binary blends are epoxy/unsaturated polyester (EP/UPE) and epoxy/polysulfide rubber (EP/PSR) while the ternary blend is epoxy/unsaturated polyester/polysulfide rubber (EP/UPE/PSR). Impact, tensile and flexural characteristics for these blends were investigated at room temperature. The morphology of impact fracture surfaces for the prepared blends was examined by using the optical microscopy. The results revealed that the blending process of epoxy resin with UPE, PSR or both together within certain weight percentages forms compatible blends with improved toughness. The brittleness phenomenon of epoxy resin disappears with increasing the content of added polymer. | ||
