Effect of fiber angles on fatigue strength of laminates composites

In this study, 8 layer composite material was used. Fiber-glass was used as the reinforcing element and epoxy was used as the matrix material. Experimental studies have been carried out on a total of 12 pieces with 0 degree and 90 degree fiber array from notched and notched samples. In the experimental study, fatigue analysis under tensile stress was performed. After the experiments, the samples were modeled in ANSYS program and fatigue analysis was performed. In layered composite materials; The effects of layer arrangement angles and notch on fatigue strength was observed. ANSYS program was compared with the results of the analyzes and the consistency between the results were examined.
