Abstract

A loose structured pref. fibrous textile in laid on an electrically conductive support and particles of a thermoplastic or thermo-setting resin are electrostatically charged and projected onto the textile whilst the conductive support is maintained electrically charged at the opposite polarity to that of the particles, so that the particles are attracted to the support and fully and uniformly impregnate the textile, which when moulded into an article a more uniform and stronger prod. is obtd.
