The purpose of the present letter is to analyse the damping properties of a bio-based composite with flax fibre. Damping parameters were investigated using beam test specimens and an impulse technique. Through a series of resonance vibration tests, the natural frequencies and modal damping were evaluated. The second part of the work was to investigate the effect of an interleave viscoelastic layer made of natural rubber on the dynamic behaviour of the composite. A comparison of the different results was performed; it shows that the viscoelastic layer had a significant influence on vibration behaviour, bending stiffness and damping factors.
