摘要
A fiber preform constituting fiber reinforcement of a composite material part that is to be fabricated is made by superposing and bonding together fiber plies, and by densifying the needled preform by introducing a material constituting the matrix of the composite material into it. During the process of making the preform, a powder is dusted onto the surface of at least some of the plies, the powder comprising at least one ingredient selected from a solid resin in powder form and solid fillers in powder form. The powder is dusted onto the surface of the top ply of the preform that is being made, prior to superposing and needling at least one additional ply.
