Abstract: This article estimated and analyzed the damping performance parameter of glass fiber, carbon fiber laminate. Based on composites classic laminate theory model combined with Vibration beam damping test to analyzed the effect of parameters on composite material such as fiber material, test load frequency, fiber angle and used Ritz finite element method and test result to prove it. The test results show that under same resin base and fiber content volume, glass fiber performance is superior to carbon fiber, and damping factor will reach extreme value when fiber at 35°. Meanwhile this article used Ritz method well estimated the effect of fiber angle on damping performance.
