Abstract
A glass fiber sizing composition for the reinforcement of resin matrices which comprises one or more adhesive agents, non-ionic lubricants, organo-silanes, and cationic lubricants as well as a coadhesive such as gelatin, another silane or some sort of glass-resin binding agent and demineralized water as a complement. The organo-silanes are from the group comprising the organo-silanes containing an organic chain of the polyazamide type and the organo-silanes whose organic chain contains at least one phenyl radical and at least two secondary or tertiary amine groups. The addition of the organo-silanes to the sizing composition improves the tensile strength of the sized strands. These organo-silanes are good organic glass-resin binding agents and their presence decreases the risk of rupture of the strands during the winding operation.
