METHOD FOR PRODUCING A CONCAVE-SHAPED IN PARTICULAR U-SHAPED PIECE IN A COMPOSITE MATERIAL AND DEVICE FOR CARRYING OUT THE SAME

摘要

The invention relates to a method fort producing a piece in a composite material with a hollow form and comprising a preform of fibres (50) embedded in a matrix, comprising placing said preform (50) in a first housing (64) defined by a mould (52) in contact with the surface of the piece to be produced outside the hollow form and a counter mould (54) in contact with the surface of the piece for production inside the hollow form, characterised in using a mould (52) in at least two parts (52.1, 52.2) and means (78) for controlling the separation of said at least two parts (52.1, 52.2) which are connected due to the phenomenon of dilatation on polymerisation.
