Abstract

A turbine engine fan casing of composite material including fiber reinforcement densified by a matrix is made as a single part with ribs that project from an inside face and/or from the outside face of the casing, each rib including a fiber reinforcement portion connected to the fiber reinforcement of a remainder of the casing by weaving or by stitching. On the inside, the ribs serve to mount acoustic panels to the inside face of the casing to form an assembly including a casing and acoustic panels. On the outside, the ribs enable equipment to be mounted on the casing.

Claims (15)

1 - 7 . (canceled)

8 . A turbine engine fan casing made of composite material, comprising:

fiber reinforcement densified by a matrix and shaped as a single part with at least one rib that projects from an inside face or an outside face of the casing;

wherein each rib comprises a fiber reinforcement portion that is connected to the fiber reinforcement of a remainder of the casing by weaving or by stitching.

9 . A fan casing according to claim 8 , wherein the fiber reinforcement is formed by a woven texture wound in superposed layers, the fiber reinforcement portion of each rib being secured to an inner or outer layer of the texture by weaving.

10 . An assembly comprising:

a fan casing; and

acoustic panels fastened to an inside face of the casing;

wherein the casing is made of composite material comprising fiber reinforcement densified by a matrix and is formed as a single part with ribs that project from the inside face of the casing and that extend axially over a fraction of an axial dimension of the casing;

each rib comprising a fiber reinforcement portion that is connected to the fiber reinforcement of a remainder of the casing by weaving or by stitching; and

the acoustic panels are housed between the ribs and are fastened thereto.

11 . An assembly according to claim 10 , wherein the fiber reinforcement is formed by a woven texture wound in superposed layers, the fiber reinforcement portion of each rib being secured to the inner layer of the texture by weaving.

12 . An assembly according to claim 10 , wherein the casing is formed as a single part also including at least one rib that projects from an outside face of the casing and that includes a fiber reinforcement portion connected to a remainder of the fiber reinforcement of the casing by weaving or by stitching.

13 . A turbine engine comprising a fan casing according to claim 8 .

14 . A turbine engine comprising an assembly according to claim 10 .
