Carbon nanotubes (CNTs) are considered to be the next-generation reinforcement material to potentially replace conventional carbon fibers for producing superhigh-performance lightweight composites.
Z. Liang et al. now report that CNT sheets of millimeter-long multi-walled nanotube reinforced bismaleimide (BMI) resin composites with improved interfacial bonding through creating covalent bonding between CNTs and resin matrix, resulting in high mechanical properties, exceed those of state-of-the-art unidirectional carbon-fiber-reinforced composites for engineering applications.
The integration of CNT nanocomposites with such high mechanical performance and outstanding electrical conductivity demonstrates great potential in developing the next generation of multifunctional composites for various applications in aerospace, automotive devices, medical devices, and sporting-goods industries.
