Process for coating fibers and applications thereof to the production of composite materials

摘要

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.
