A method of making a fiber preform for constituting a reinforcing fabric of a part made of composite material, the method comprising forming one-directionalfiber sheets, superposing the sheets with pairs of adjacent sheets having different directions, and needling together the superposed sheets, wherein sheets are used that are made up of elements which are formed by assembling together mutually parallel discontinuous filaments or fibers substantially without twisting with cohesion between the fibres or filaments being provided by covering by means of a yarn of fugitive material.
Cette invention concerne un procédé de réalisation de préformes fibreuses entrant dans la fabrication d'un tissu de renfort pour pièces en matériau composite, ledit procédé comprenant la formation de nappes fibreuses unidirectionnelles, la superposition de plusieurs nappes unidirectionnelles orientées différemment, aiguilletage des nappes superposées. Les nappes utilisées sont faites d'éléments issus de l'assemblage essentiellement sans torsion de filaments ou fibres discontinus mutuellement parallèles, la cohésion entre fibres ou filaments étant obtenue au moyen de fils de liage en matériau éventuellement éliminable ou "fugitif".
