Abstract: front page image
(EN)The invention relates to an exhaust pipe (20) comprising the following elements which are disposed concentrically, namely: an inner tube which is made from an inorganic matrix composite (22); an outer metal tube (24); and a support layer (26) which is made from a fibrous material. The thickness of the support layer (26) measures between 2 mm and 10 mm and preferably between 3 mm and 6 mm. The maximum support pressure exerted by the support layer (26) on the inner tube (22) is between 10-4 MPa and 10-1 MPa.
(FR)Ce conduit d'échappement (20) comporte, disposés de manière concentrique : - un tube interne en composite à matrice inorganique (22) ; - un tube externe métallique (24) ; - une couche de maintien (26) d'un matériau fibreux. L'épaisseur de la couche de maintien (26) est comprise entre 2 mm et 10 mm, et de préférence entre 3 mm et 6 mm. La pression de maintien minimale exercée par la couche de maintien (26) sur le tube interne (22) est comprise entre 10-4 MPa et 10-1 MPa.
