| Abstract | ||
| In this work, preparation ternary polymer blends, by addition PMMA to the two groups of binary polymer blends (98%Epoxy: 2%NR) and (95%Epoxy: 5%NR). Mechanical properties for all prepared samples were studied. The results of this research showed that the ternary polymer blends which have the ratios (93%Epoxy: 2 %NR: 5%PMMA) or (90%Epoxy: 5 %NR: 5%PMMA) have the best results in fracture strength, young modulus, compressive strength, and hardness and the maximum values were at 5%PMMA, while elongation decreases with the addition PMMA to the blends. Moreover flexural properties values, impact strength and fracture toughness decrease with increasing in PMMA percentage for both groups, these polymer blends were characterized for morphology using scanning electron microscopy (SEM). | ||
