Abstract: An assembly includes an inner wall delimiting a cavity, the inner wall having a first surface facing the cavity, and a second surface opposite the first surface with respect to the cavity, and a sealing device attached to the second surface and including a sealing layer including a material expandable when an opening is formed in the inner wall, and a guide attached to the sealing layer so as to exert a stress on the sealing layer to control a direction of expansion of the material of the sealing layer. The sealing layer has a first face and a second face, and the guide includes a first film attached to the first face and a second film attached to the second face.

Abstract: A pneumatic deicing device (1) for breaking and removing an ice deposit accumulated on the outer surface (2) of an aircraft, in particular on an airplane wing. The device (1) includes an outer layer (10) intended to withstand the outside environment, an inner interface layer (50) intended to be bonded to the outer surface of the aircraft, and at least two outer (30) and inner (40) intermediate layers connected to one another by a network of stitches (36) spaced apart to define deicing chambers (35) that can be inflated using injected pressurized air so as to create an expansion of the device causing a mechanical action to break the ice. The inner interface layer (50) with the outer surface (2) of the aircraft includes at least one textile layer (54) having an inner surface (55) intended to be in direct contact with an outer surface (2) of the aircraft.

The outer intermediate layer (30) includes a knit textile layer (34). At least one interlayer (20; 32) made from polar elastomer material is arranged above the knit textile layer (34) and immediately in contact with the outer layer (15) and the knit textile layer (34).

Abstract: A flexible fuel tank (10) has, from the inside to the outside of the tank: a single-layer or multilayer liner (2) having properties of sealing with respect to the liquid, impermeability to the vapor of said fuel, and dissipation of electrostatic charges. The liner (2) includes an inner face (2a) intended to be in contact with the fuel and an outer face (2b). An intermediate layer (3) is in contact with the outer face (2b) of the liner (2), for example a coating layer; and a textile reinforcing layer (4) is in contact with the intermediate layer (3).

Abstract: Embodiments of the present invention relate generally to fuel tanks for aviation, and particularly to construction of rigid tank walls that have been found useful in absorbing energy of a magnitude expected during a crash. In some aspects, the rigid tank wall construction includes particular materials, such as a thermoplastic resin matrix. In some aspects, the rigid tank wall construction includes a particular arrangement of reinforcing fibers, such as a twill weave pattern.
