Aircraft conduit

1. A pipe integrated into aircraft piping, the pipe produced from a composite material comprising a fiber-reinforced geopolymer resin matrix, the composite material comprising woven fibers impregnated with a sialate-type geopolymer resin (xSiO 2 , AlO 2 ), in which x is between or equal to 1.75 and 50, wherein a finish has been at least partially removed from the fibers prior to impregnation with the geopolymer resin.

2. The pipe according to claim 1 , wherein the pipe comprises two pipes, a first internal pipe ( 26 ) into which a fluid can flow, whereby said internal pipe ( 26 ) is placed inside a second external pipe ( 28 ).

3. A method of manufacturing a pipe to be integrated into aircraft piping, the pipe being produced from a composite material comprising a fiber-reinforced geopolymer resin matrix, the composite material comprising woven fibers impregnated with a sialate-type geopolymer resin (xSiO 2 , AlO 2 ), in which x is between or equal to 1.75 and 50, said method comprising a step of at least partially removing a finish from the fibers prior to impregnation with the geopolymer resin.

4. The method of claim 3 , wherein said removing step removes between 50% and 90% of the finish.

5. The method of claim 3 , comprising the further step of improving fluidity of said resin and obtaining a homogenization of a migration of the resin in the fibers by adding water in the resin in an amount from 3% to 7% by volume, wherein impregnation of the fibers is improved.

6. A pipe integrated into an aircraft piping, the pipe obtained by the method according to claim 3 .

7. Aircraft piping that comprises at least one pipe according to claim 6 .

8. Aircraft piping according to claim 7 , comprising:

two pipes, a first internal pipe ( 26 ) into which a fluid can flow, and a second external pipe ( 28 ),

wherein said internal pipe ( 26 ) is located inside the external pipe ( 28 ).

9. A pipe according to claim 1 , wherein the pipe is comprised of a first internal pipe ( 26 ) into which a fluid can flow, and a second external pipe ( 28 ), said internal pipe ( 26 ) located inside the external pipe ( 28 ),

said internal pipe and said external pipe being made of the same resin matrix.

10. Aircraft piping, comprising:

a first internal pipe ( 26 ) into which a fluid can flow between a first end and a second end;

a second external pipe ( 28 ), said internal pipe ( 26 ) located inside the external pipe ( 28 ); and

connection elements located at each of the first end and second end, the connection elements providing for connection to further aircraft fluid elements,

the internal pipe and the external pipe being made of the same composite material that comprises a fiber-reinforced geopolymer resin of a sialate-type geopolymer resin (xSiO 2 , AlO 2 ), in which x is between or equal to 1.75 and 50 wherein a finish has been at least partially removed from the fibers prior to impregnation with the geopolymer resin.
