Carbon fibers in reinforced plastics have revolutionized industries that require strong and lightweight materials. However, their application is hindered by inherently poor electrical and thermal conductivity.
A new study, a scientific report published in the journal, shows that through the growing number of nanomaterials, especially carbon nanotubes, the surface of carbon fibers can also be given these necessary properties.
This research conducted by the University of Surrey’s Institute of Advanced Technology (ATI) and the University of Bristol’s Center for Advanced Composites for Innovation and Science (ACCIS) shows that carbon fiber reinforced plastics have the potential for multiple functions while still maintaining their functions. Structural integrity. It is now possible to integrate novel functions including sensors, energy harvesting lighting equipment and communication antennas into the structure of composite materials to create a new era of composite material technology.
ACCIS Research Assistant Dr. Thomas Pozegic, who was a PhD student at the University of Surrey, explained: “The aerospace industry still relies on metal structures in the form of copper meshes to provide lightning protection and prevent static charge buildup. The upper surface of carbon fiber composites has poor conductivity. The increased weight makes the manufacture of carbon fiber composite materials difficult. The material we developed utilizes high-density growth of high-quality carbon nanotubes, so that electrical transmission materials can be carried out in the entire composite material."
ACCIS polymer and composites reader Dr. Ian Hamerton commented: "Studies have shown that carbon nanotubes can significantly improve the thermal conductivity of carbon fiber composites. This will bring a wide range of benefits in the aerospace industry by enhancing decarburization performance. It provides a solution to reduce the formation of fuel vapor at cruising altitude."
Professor Ravi Silva, Director of ATI and Head of the Nanoelectronics Center (NEC), said: "In the future, carbon nanotube-modified carbon fiber composites may bring exciting possibilities, such as energy harvesting and storage structures with self-healing functions. This prototype is currently being studied, and there are many ideas, including incorporating current aerospace/satellite technology into automotive design."
