Abstract
A process for manufacturing a piece made of composite material with a hollow form and including a fiber preform (50) that is embedded in a matrix, includes placing the preform (50) in a first chamber (64) delimited by a mold (52) that is in contact with the surface of the piece to be produced outside of the hollow form and a counter-mold (54) that is in contact with the surface of the piece to be produced inside of the hollow form, and using a mold (52) that is made in at least two parts (52.1, 52.2) and elements (78) for controlling the spacing of the at least two parts (52.1, 52.2) that are contiguous using the expansion phenomenon during the polymerization phase.
