Abstract
Natural fibre composites have gained special attention due to their relatively good mechanical properties. So they have been seen as substitute to the synthetic fibre composites in structural applications in function of their disposable reduction problems. Since they can be employed as structural materials, their mechanical behaviour needs to be known. The objective of this study is to evaluate the dynamic behaviour of a composite material manufactured from cotton fiber. Samples of this composite at three different orientation of fibre are tested: [0°]8,[±45°]2S and [90°]8. The natural frequencies and the damping factors are experimentally determined. The Young’s Modulus obtained at tensile test was compared to that theoretically obtained by means of dynamic test. It was expected that cotton fibre composite presented a good performance in absorbing vibrations, but according to the dynamic test, it presented a low damping factor.
