摘要

glass wire coated with a sizing composition, aqueous glass wire sizing composition, process for preparing a sizing composition and composite comprising at least one organic and / or inorganic matter and reinforcing glass wires. The invention relates to glass yarns coated with a sizing composition comprising (by weight%): - 25 to 90% of at least one filmogenic agent - 3 to 25% of at least one coupling agent - 2 to 18 % of nanoparticles. It also relates to a sizing composition suitable for coating said yarns, their process of obtaining and the composites incorporating such yarns. The glass threads of the invention have a high resistance to wet aging.
