[Abstract]

Researchers at Pusan National University have developed an ultra-low-viscosity reactive copolymer resin that enables fast and uniform manufacturing of recyclable fiber-reinforced thermoplastic composites. This technology overcomes the processing limitations of conventional thermoplastic composites while simultaneously achieving excellent mechanical performance, reliability, and recyclability. The developed composites achieved an interlaminar shear strength (ILSS) of 72.2 MPa through enhanced fiber-matrix interfacial bonding by construction of transcrystalline interphase, demonstrating strong potential as next-generation lightweight structural materials for unmanned aerial vehicles, drones, wind turbine blades, and other advanced mobility applications.
