The Effects of Fiber Orientation on the Vibration Modal Behavior of Carbon Fiber Plain Woven Fabric/Epoxy Resin Composites

Abstract:

The modal properties of carbon fiber woven fabric / epoxy resin composites with different fiber orientation angles were studied by using single input single output free vibration of cantilever beam hammering modal analysis method. With the same fiber volume fraction, the different fiber orientation of the laminated composite has an effect on parameters of vibration mode of composites. The experimental results show that with the fiber orientation increasing, the natural frequency of laminated composites becomes smaller and damping ratio becomes larger. The fiber orientation smaller, the peak value of natural frequency becomes higher and the attenuating degree of acceleration amplitude becomes slower.
