Vibraion analaysis of the laminated composites beam

In this study, 9 pieces laminated composite U profile beam which fixed from one end and has 8 layer with different array angle were produced with fiber glass and epoxy. The natural frequencies of these beams were measured in experimental environment and then the samples were modeled in Ansys finite element method to performed vibration analysis. The naturel frequencies in the vertical direction obtained by the Ansys program were compared with obtained from experimental measurements. As a result, it was seen that the data of the numerical and experimental results were consistent with each other.
