Abstract

AMELIORATION AUX MATERIAUX COMPOSITES COMPRENANT UN TISSU DE FILS DE SILICE DANS LEQUEL SONT INSERES, A INTERVALLES REGULIERS ET DE PREFERENCE DANS LE SENS DE LA CHAINE DU TISSU, DES FILS ELECTRIQUEMENT CONDUCTEURS ISOLES ELECTRIQUEMENT PAR RAPPORT AUX SURFACES EXTERNES DU TISSU. LES FILS ELECTRIQUEMENT CONDUCTEURS PRESENTENT DES ONDULATIONS QUI PEUVENT ETRE OBTENUES SOIT EN LES ENROULANT EN SPIRALE AUTOUR D'UN FIL DE SILICE INSERE DANS LE TISSU PAR TISSAGE OU PAR COUTURE, SOIT PAR ONDULATION DES FILS DANS LE PLAN DU TISSU OU DANS DES PLANS PERPENDICULAIRES A CE DERNIER LORS DU TISSAGE. APPLICATION NOTAMMENT A LA DETECTION DES FUITES DE METAUX LIQUIDES.
