A method for producing a hollow composite fibre component comprising reinforcing fibres embedded in resin, comprising individual steps: a) in which an expendable starting mould is surrounded with at least one layer of first reinforcing fibres, b) in which the first reinforcing fibres are permanently covered with a resilient sealant in order to form a reusable, tube-type shaped article so that the starting mould is located in a pressure chamber, which can be placed under pressure, of the shaped article, c) in which a pressure medium line is installed in a sealed manner on at least one remaining opening of the shaped article, d) in which the starting mould is removed, e) in which the shaped article is pumped up to a first predetermined pressure value by supplying a pressure medium into the pressure chamber via the pressure medium line, f) in which the pumped-up shaped article is surrounded with at least one layer of second reinforcing fibres, g) in which the shaped article covered with the second reinforcing fibres is inserted into a split mould which determines the outer contour of the composite fibre component, h) in which a resin is introduced into the mould enclosing the second reinforcing fibres, and the pressure in the pressure chamber of the shaped article at the time of the resin being supplied is higher than the first pressure value, i) in which the temperature is increased until the resin cures and j) a step in which the pressure is released from the shaped article, the mould is opened, the composite fibre component is taken out of the mould and the shaped article is removed from the composite fibre component containing the second reinforcing fibres. a) in which an expendable starting mould is surrounded with at least one layer of first reinforcing fibres, b) in which the first reinforcing fibres are permanently covered with a resilient sealant in order to form a reusable, tube-type shaped article so that the starting mould is located in a pressure chamber, which can be placed under pressure, of the shaped article, c) in which a pressure medium line is installed in a sealed manner on at least one remaining opening of the shaped article, d) in which the starting mould is removed, e) in which the shaped article is pumped up to a first predetermined pressure value by supplying a pressure medium into the pressure chamber via the pressure medium line, f) in which the pumped-up shaped article is surrounded with at least one layer of second reinforcing fibres, g) in which the shaped article covered with the second reinforcing fibres is inserted into a split mould which determines the outer contour of the composite fibre component, h) in which a resin is introduced into the mould enclosing the second reinforcing fibres, and the pressure in the pressure chamber of the shaped article at the time of the resin being supplied is higher than the first pressure value, i) in which the temperature is increased until the resin cures and j) a step in which the pressure is released from the shaped article, the mould is opened, the composite fibre component is taken out of the mould and the shaped article is removed from the composite fibre component containing the second reinforcing fibres.
