Abstract: The invention concerns a turbine engine with an axis of rotation B comprising a blower casing (10) and a blower (V) with movable blades (17). A clearance lies between the internal surface of the casing and the free ends of the blades. A bearing of the blower is connected to fixed parts of the turbine engine by connections such that, in the event of a load on the blower blades, these connections break and the axis of rotation of the blower oscillates about the axis of rotation B. The casing comprises, bonded to its internal surface and over at least part of the extent of the clearance, a layer of thermoformable foam (19) placed opposite the ends of the blades (17) of the blower (V).

Abstract: A process for producing a hollow article made of a composite material of reinforcing fibers embedded in a matrix of hot-polymerized resin includes a step in which at least one core made of a silicone elastomer is draped with at least one layer of resin-impregnated reinforcing fibers. A resultant assembly is moulded to shape the internal and external surfaces of the hollow article by simultaneous inward and outward compression of at least one resin-impregnated fiber layer caused by movement of mould walls towards each other and by thermal expansion of at least one core.
