The results highlight and interpret the testing and properties of natural fibre composites including, non-destructive and high strain rate testing. The potential of this material for noise enclosures is investigated by using a coupled method cnoidal – Extended Finite Element Method (XFEM). XFEM enables the accurate approximation of solutions with jumps, discontinuities or general high gradients across interfaces. The dissipation of the sound power into a plate/cavity system shows the efficiency of this composite to achieve noise reduction better to that obtained at low and higher frequencies with traditional foams.
