TY - JOUR ID - TI - Study the of effect of micro and nanoCadmium Oxide on the hardness test of (epoxy-polyurethane) blend AU - Ghasaq Talal Suhail AU - Faik Hammad Anter AU - Ziyad Shihab Al-Sarraj PY - 2018 VL - 59 IS - 4B SP - 2020 EP - 2025 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - This research includes using epoxy resin and polyurethane resin to form a blend (EP+PU) with different resin ratios (90 – 10)%, (80 – 20)%, (70 – 30)%, and (60 – 40)% to achieve best ratio for impact strength as a function of better toughness; then reinforced with micro and nano (CdO) with weight fraction (0.02, 0.04, 0.06, 0.08). Mechanical properties were studied including hardness before and after exposure to UV irradiation. Results showed that the composite (nano CdO+ blend) had better properties compared with (micro CdO+ blend) composite. Also hardness show increases with increasing the weight fraction for all samples.
