Abstract (en)

[origin: WO2010072967A1] The invention relates to a hollow form part obtained by 3D weaving and impregnation. The invention comprises making a preform (11) by three-dimensional weaving while carrying out a partial untying (19) during the weaving, which enables the subsequent formation of a cavity within the woven mass and the stabilisation of the form during the impregnation phase.
