TURBINE ENGINE FAN CASING AND AN ASSEMBLY FORMED BY SUCH A CASING AND ACOUSTIC PANELS
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.
