Abstract (en)

[origin: WO9744181A1] The invention discloses composite material tubes, piles, masts subjected to axial compression or bending stresses, produced by an adapted winding of weft-unbalanced woven fabric, such that the main portion of reinforcement fibres is placed parallel to the longitudinal axis of the structure. The tubes, piles and masts are produced by winding on a compressible mandrel to ensure that the tubes are not stressed or subjected to micro-cracking when the mandrel plug is pulled out.
