Process for the manufacture of continuous glass filaments. The process consists in depositing on the glass filaments being drawn a size consisting of a solution whose solvent content is lower than 5 % by weight, the said solution including a mixture of components that are polymerisable and/or crosslinkable by heat treatment, the said components being, in the case of at least 60 % by weight thereof, components whose molecular mass is lower than 750, less than 10 % by weight of film-forming agents and from 0 to 25 % by weight of bridging agents, lubricating agents, stabilising agents and initiators and/or catalysts, the said agents being optionally polymerisable and/or crosslinkable by heat treatment, in reeling the filament(s) formed by bringing together the said filaments onto a rotating support to form a winding consisting of turns of filament coated with an unpolymerised size. The filaments are intended for the reinforcement of thermoplastic or heat-curable organic substances or of substances of inorganic origin. |
