Patent ID: 8628709

Claim:
A process for manufacturing a piece made of composite material with a hollow form, comprising: placing a preform ( 50 ) in a first chamber ( 64 ) delimited by a mold ( 52 ) fiber that is in contact with a surface of an outside of the hollow form, the mold being in at least two parts ( 52 . 1 , 52 . 2 ); contacting a surface of the piece inside of the hollow form; and polymerizing matrix of the piece, wherein a controller ( 78 ) controls spacing such that said at least two parts ( 52 . 1 , 52 . 2 ) are configured by edges or stops to be contiguous along an attachment plane ( 80 ) utilizing an expansion phenomenon during the polymerizing, and said at least two parts ( 52 . 1 , 52 . 2 ) are separated prior to polymerization or after polymerization.
