Abstract

In this study, the effect of number of carbon layer, its position and orientation angle of the laminate on the natural frequency and mode shape for hybrid fiber (carbon/glass) with epoxy composite laminates are investigated. Numerical analyses are carried outto study vibrationbehavior of composite laminated beams using ANSYS 13 software.The results show that the natural frequencies increased when the number of carbon layerincreases and decreased when the carbon layer position changes from the surface towards mid-plane, also; the natural frequencies change with changing orientation angle.
