Abstract
This study aimed to investigate the defects and techniques of predicting the fatigue life of Nano-polymeric composites structures. This paper provides to studied the fatigue life prediction of polymer matrix reinforced by nano-particles (Nano-ZrO2). The fatigue stress ratio is R= -1. All Samples are usually manufacturing and divided from the mass of polymeric nano-ZrO2composites. The major property of nano-polmeric composite is depending on the dispersion process of nano ZrO2 in the resin. Specimen surface preparations play an important function in fatigue life. The polymer matrix contain nano-Zirconia will be decrease the brittle fracture of matrix enhance the roughness of the composite surface and the maximum fatigue stress, fatigue life under vayring loads. Better fatigue life was done when nano–materials reach to 3% from the total volume of specimen.
