تأثير التقوية بمسحوق أوكسيد الزنك على الخواص الميكانيكية لمادة متراكبة ذات أساس من البولي استر غير مشبع

الملخص EN

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 the tests 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.
