Epoxy film former, urethane film former, silane package including aminosilane coupling agent and epoxysilane coupling agent, cationic lubricant, nonionic lubricant, antistatic agent, and sizing containing at least one acid A composition is provided. The epoxy resin emulsion includes a low molecular weight liquid epoxy resin and one or more surfactants. The epoxy resin preferably has an epoxy equivalent of 185 to 192. The sizing composition may contain methacryloxysilane as necessary. Using the above sizing composition, glass fibers used in filament winding applications are sized and reinforced with improved mechanical properties, wet tensile properties, improved resistance to cracks and improved processing properties Composite articles can be manufactured. |
