  • Making a blank by reinforcing a fiber structure and/or bonding fiber structures together, and use in making composite material parts
    Publication number: 20040175553
    Abstract: A porous fiber structure is consolidated by forming within a deposit of a refractory material by partially densifying the fiber structure in such a manner as to bond together the fibers of the fiber structure so as to enable the fiber structure to be handled without being deformed, while leaving empty the major fraction of the initial pore volume of the fiber structure, and rigid pins are implanted through the consolidated porous structure. A blank is obtained by reinforcing a fiber structure by implanting pins or by bonding together consolidated fiber structures, the bonding being performed by implanting pins.

  • Making a needled fiber preform for fabricating a composite material part
    Publication number: 20030136502
    Abstract: 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.

  • Method of manufacturing a part made of composite material comprising fiber reinforcement consolidated by a liquid process
    Patent number: 5486379
    Abstract: A fiber preform constituting the fiber reinforcement of the part to be made is itself made by shaping and consolidating a fiber fabric by a liquid process. An interphase layer between the fibers and the matrix is formed on the consolidated preform prior to densification thereof with the matrix, such that the operation of densifying the consolidated preform can be performed without requiring supporting tooling therefor.

  • Production of infusible polycarbosilanes convertible into silicon carbide ceramics
    Patent number: 5064915
    Abstract: Infusible and insoluble polycarbosilanes, readily pyrolyzed into silicon carbide ceramic materials, e.g., SiC fibers, are produced by hardening a fusible polycarbosilane containing at least two .tbd.SiH groups per molecule via intimately contacting such fusible polycarbosilane with an effective hardening amount of the vapors of sulfur.
