The invention relates to a mat comprising discontinuous natural fibres and discontinuous glass fibres and the fibrous structures which may be generated using said mat, whereby said structures are for reinforcing composite materials. The presence of natural fibres in the mat lends the property of being easy to manipulate and particularly in eradicating the awkward tendency of a mat made exclusively from glass fibre to bend in an uncontrolled manner. Furthermore the mechanical properties of the final composite material are remarkable in particular with regard to the modulus of traction and flexion.
L'invention concerne un mat comprenant des fibres naturelles discontinues et des fibres de verre discontinues, et les structures fibreuses pouvant être réalisées à l'aide dudit mat, lesdites structures étant destinées à renforcer les matériaux composites. La présence de fibres naturelles dans le mat donne à celui-~ci la propriété d'être facile à manipuler, notamment en supprimant la fâcheuse tendance des mats exclusivement en fibre de verre à se plier de façon incontrôlée. De plus, les propriétés mécaniques du matériau composite final sont remarquables, en particulier sur le plan du module de traction et de flexion.
