New approach to fabricate densificated continuous fiber reinforced polytetrafluoroethylene composites with significantly improved interfacial bonding and mechanical properties

摘要

An unique two-step technique to fabricate densified continuous fiber reinforced polytetrafluoroethylene (PTFE) composites with significantly improved interfacial bonding and mechanical properties have been successfully developed. The technique is conventional sintering followed by resin film infusion (RFI). The mechanical properties of the composites were studied, and results show that the composites have significantly improved interfacial bonding and mechanical properties.
