The invention relates to a composite material including a matrix of a thermoplastic material and a charge of dense exotic wood fibres. According to the invention, the wood used for the fibres has a density of at least 640 kg/m3 and the charge of wood fibres has a mass proportion lower than a critical proportion at which a percolation path is established in the composite material by the contact between the fibres and the charge. |
