| Abstract | ||
| From polymer blends can be obtained more useful properties compared with single polymer. In this work, polymer blend (Epoxy (EP): Natural Rubber (NR)) with different ratios of NR (0, 2, 3.5 and 5%wt) and ternary polymer blend with ratio of (Epoxy: 2%NR: 5% wt. PMMA) were prepared. The Mechanical properties were included (tensile, flexural, impact, compression) tests and analytical physical properties (FTIR, SEM) were investigated, and the results show that the elongation values, impact strength and fracture toughness for polymer blend system (Epoxy: NR) were increment with increase natural rubber ratio in the polymer blend system. Whereas fracture strength, young’s modulus, flexural strength, flexural modulus and maximum shear stress decreased. The highest values of impact strength and fracture toughness were (0.041KJ/m2) and (0.321 MPa √m) respectively for polymers blend (95% Epoxy: 5% NR). Ductile fracture in rubber modified epoxy may be produce from the elastomeric nature of rubber which is represents an energy dissipating center. | ||
