Triple‐Coupled Organic‐Nano‐Transcrystalline Interphase Constructed via Eco‐Friendly Crosslinkable Polyamide‐Imide/Carboxylated CNT Waterborne Sizing for High Performance CF / PEEK Composites
Carbon fiber reinforced polyetheretherketone (CF/PEEK) composites suffer from severe fiber‐matrix modulus mismatch and weak interfacial adhesion, limiting their mechanical performance. Herein, eco‐friendly waterborne sizing agents consisting of self‐crosslinkable polyamide‐imide (CPI) and carboxylated carbon nanotube...
