Process for the production of sized glass filaments consisting in coating the glass filaments with a size capable of polymerizing thermally, consisting of a solution whose solvent content is lower than 5 % by weight and viscosity lower than 400 cP, the said solution including a thermally polymerisable and/or crosslinkable base structure, the said structure including at least 60 % by weight of one or more components of molecular mass lower than 750, containing at least one acrylic and/or methacrylic and/or vinyl ether and/or N-vinylamide and/or N-vinyllactam functional group, the proportion of polyfunctional component(s) within the said components being at least 45 % by weight of the said components, so as to obtain glass filaments coated with an unpolymerised size capable of polymerising thermally. The invention also relates to the sized glass filaments obtained and the composites produced from the said filaments. |
