The present invention relates to glass strands coated with a composition size comprising at least one silane corresponding to the formula: If (R1) (R2) (R3) (R4) in which: R1, R2 are alkoxy groups, R3 is an alkoxy group or a radical based solely on carbon, hydrogen and possibly nitrogen, R4 is a radical based solely on carbon, hydrogen and possibly nitrogen, comprising at least one unsaturated ring substituted by at least one unsaturated chain conjugated with the ring. The glass strands according to the invention are particularly resistant in the medium corrosive. |
