The invention relates to a method for the impregnation of continuous fibres that comprises coating said fibres with a polymer matrix containing: (a) at least one fluorinated polymer grafted with at least one carboxylic polar function and (b) optionally at least one fluorinated non-grafted polymer. The invention also relates to the composite fibres that can be obtained by said method, and to the use thereof. La présente invention concerne un procédé d'imprégnation de fibres continues, comprenant l'enrobage desdites fibres par une matrice polymérique comprenant : (a) au moins un polymère fluoré greffe par au moins une fonction polaire carboxylique et (b) éventuellement au moins un polymère fluoré non greffé. Elle concerne également les fibres composites susceptibles d'être obtenues selon ce procédé, ainsi que leurs utilisations.
