Abstract
The present invention relates to a process for coating reinforcing elements preferably in fiber form, wherein said material is treated, between two electrodes, by the field obtained by means of a direct electric current of voltage included between 50 and 150,000 V and/or by means of an alternating electric current of frequency between 50 and 1,000 Hz and of voltage included between 10,000 and 30,000 V, and said element is placed in contact with a powder of a conductive or semi-conductive material.
