More Information
Summary:The invention provides a carbon fiber sizing agent and a sizing method thereof. A polyurethane resin is added into an epoxy resin sizing agent, the drying temperature after sizing is strictly controlled, and carbon fiber bundles with good rubbing resistance and splitting performance simultaneously can be obtained, so that the problems that the requirements on two aspects such as good rubbing resistance and splitting performance are difficultly simultaneously met by the sizing agent which takes an epoxy resin as a main component are solved.
