Abstract

Composition de liaison de fibres de verre, comportant une quantité suffisante d'une résine furannique aqueuse et soluble pour assurer la liaison, de 15 à 99 % en poids d'eau, et une quantité efficace d'un catalyseur apte à provoquer le durcissement de la résine. On a également prévu un procédé de liaison de fibres de verre au niveau des jonctions des fibres. Il consiste à se munir de fibres de verre nouvellement formées, à appliquer sur les jonctions des fibres une quantité suffisante d'une résine furannique aqueuse et soluble pour assurer la liaison, et à provoquer le durcissement de la résine au niveau des jonctions des fibres de verre. Enfin, on a prévu une composition de fibres de verre comprenant une pluralité de fibres de verre possédant une pluralité de jonctions entre au moins deux fibres, ainsi qu'une quantité suffisante d'une résine furannique aqueuse et soluble pour assurer la liaison, laquelle résine comporte de 15 à 99 % en poids d'eau, et est appliquée sur les jonctions des fibres de verre.
