Abstract

The damping properties of 3D braided composites are studied by the free vibration method of cantilever beams, and the influencing factors including braiding angles, fiber volume fractions and braiding structure are discussed. The longitudinal elastic modulus of composites are defined by the frequency and modality measured. The experimental results show that the damping properties of composites are improved while the braiding angle increases or the fiber volume fraction decreases, and that the damping properties for the five-directional braiding structure are superior to the four-directional braiding structure. In addition, the variation trends of the longitudinal elastic modulus with the braiding parameters agree with the results in the literature.
