TY - JOUR ID - TI - Effect of Reinforced by Zinc Oxide Powder on the Mechanical Properties forUn-saturated Polyester Matrix Composite Material تأثير التقوية بمسحوق أوكسيد الزنك على الخواص الميكانيكية لمادة متراكبة ذات أساس من البولي أستر غير المشبع AU - هناء عرير سميج PY - 2011 VL - 29 IS - 10 SP - 474 EP - 484 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - This research is devoted to the preparation of polymer matrix composite materials by (Hand Lay-Up ) method, where the composite material was prepared from the unsaturated polyester resin (UP) as a matrix reinforced by Zinc Oxide with volume fractions (0% , 1% , 2% , 3% ,4% ) .several of mechanical tests were done and these includes Impact, Bending, Flexural Strength, Shear Stress and Hardness, Result of thetests shows that the values of (Bending elastic modulus, Flexural Strength , Fracture Toughness, Hardness and Shear Stress) increase with the increase of Zinc Oxide particle volume fraction, but the values of Impact Strength decreased with the increases of volume fraction of Zinc Oxide particles.
