1. A consolidation method comprising:
placing a fibrous preform in a shaping recess of a shaping tool,
supplying the shaping tool with a gas phase to obtain a deposit in the fibrous preform, the shaping tool for vapor phase chemical infiltration of a fibrous preform comprising a first portion, one face of which has a first shaping zone surrounded by a first edge zone of the first portion, and a second portion, one face of which has a second shaping zone surrounded by a second edge zone of the second portion, the first and the second shaping zone defining, when the first edge zone is brought into contact with the second edge zone, a shaping recess with a given shape intended to receive the fibrous preform, wherein at least one gas injection port is present at least partially in the first or in the second edge zone and a gas outlet port is present at least partially in the first or in the second edge zone, the gas injection port and the gas outlet port placing the shaping recess in fluid communication with the outside of the shaping tool,
and wherein outer faces of the first and of the second portion are impermeable to gas.
