  • Casing made of organic matrix composite material that facilitates the discharge of smoke
    Patent number: 9920769
    Abstract: A gas turbine casing made of organic matrix composite material includes reinforcement densified by an organic matrix defines an inside volume. On its inside face the casing has a structural part with a first face facing the inside face of the casing, and an opposite second face defining a flow passage portion. Recesses opening out into the inside volume of the casing are present between the inside face of the casing and the first face of the structural part facing the inside face of the casing. In the event of a fire, the recesses allow gas coming from degradation of the resin of the casing to be discharged into the flow passage.

  • FIRE PROTECTION OF A PART MADE OF A THREE-DIMENSIONAL WOVEN COMPOSITE MATERIAL
    Publication number: 20160327061
    Abstract: The invention relates to a method for fire protection (S) of a part (1) of a gas-turbine engine made of a composite material comprising a main fibrous reinforcement compregnated by a main matrix, the protection method (S) comprising the following steps: preforming (S1) a panel of pre-preg (20) such as to grant same a shape corresponding to the shape of a surface (3) of the part (1) to be protected against fire, said panel of prepreg (20) comprising a secondary fibrous reinforcement compregnated by a secondary matrix; applying (S2) the panel of prepreg (20) thus preformed to the part (1); and securing (S3) the panel of prepreg (20) to the surface (3) by thermal treatment of the part (1) provided with said panel of prepreg (20) in order to obtain a fire-protection layer (2).
