METHOD OF MANUFACTURING OF CARBON FIBERS REINFORCED COMPOSITES IMPROVED MECHANICAL INTERFACE STRENGTH

摘要

PURPOSE: A carbon fiber strengthening complex production method with improved mechanical interfacial strength is provided to improve a mechanical interfacial strength with a thermoplastic matrix by using a carbon fiber sizing processed with a sizing agent as a reinforcing agent. CONSTITUTION: The carbon fiber strengthening complex production method is processed by dipping the carbon fiber into a sizing agent. A sizing bath exposure time of the carbon fiber is 10 second to 60 minutes and the carbon fiber is included within a finally manufactured composite to 10-50 weight%. In the carbon fiber strengthening composite production, a suitable temperature for heating press is 200- 265°C and its suitable pressure is 2.0 to 10.0 MPa.
