Abstract: This article aims at the sensitivity analyzing of the performance parameter of composite laminate combined with cantilever beam vibration test and strain energy finite element simulation to cross authenticate. The test result shows that the fiber type, fiber volume content, fiber angle and loading frequency are all important parameters which influence the damping performance of composites. Fiber angle and loading frequency show significant influence on composites. Meanwhile, the strain energy finite element method this article used is fitting well with the test result and can be used to estimate the damping factor of composite laminate under different fiber angles.
