Method for applying a vacuum bag around a fuselage barrel made of composite material to be polymerized
Abstract
A vacuum bag is applied around a fuselage barrel (11) made of composite material to be polymerized, formed by means of lamination on the outer surface of a mandrel (10) having the form of a solid of rotation about a longitudinal axis (x). A bag material in the form of a sheet (30) having a transverse width corresponding to the longitudinal length of the fuselage barrel (11) is provided alongside the mandrel. A first transverse end portion (30a) of the sheet is fastened or sealed on the outer surface of the barrel (11) or the mandrel (10). Then the mandrel is rotated around the axis (x), so as to wrap the sheet (30) about the barrel (11). While the mandrel (10) rotates, the opposite axial end edges (30d) of the sheet (30) are sealed on the mandrel (10). Finally, a second transverse end portion (30b) of the sheet is sealed on the outer surface of the barrel (11) or the mandrel.
