    摘要: A sizing composition containing an epoxy film former, a urethane film former, a silane package that includes an aminosilane coupling agent and an epoxy silane coupling agent, a cationic lubricant, a non-ionic lubricant, an antistatic agent, and at least one acid 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 weight from 185-192. The sizing composition may optionally contain a methacryloxy silane. The sizing composition may be used to size glass fibers used in filament winding applications to form reinforced composite articles with improved mechanical properties, wet tensile properties, improved resistance to cracking, and improved processing characteristics.
