The Effects of Fiber volume fraction on the Experiment Modal Behavior of 0°/90℃ Carbon Fiber Plain Woven Fabric/Epoxy Resin Composites
A study on dynamic mechanical properties of carbon fiber plain woven fabric (with fiber orientation of 0°/90°)/epoxy resin laminated composites with different fiber volume fraction was carried out.The test method is single input single output free vibration of cantilever beam hammering modal analysis method.The effect of different fiber volume fraction on the modal parameters of laminated composites was analyzed.The experimental results show that with the fiber volume fraction increasing,the natural frequency of laminated composites becomes larger and damping ratio becomes smaller.The fiber volume fraction is greater,the peak value of natural frequency becomes higher and the attenuating degree of acceleration amplitude becomes slower.
