Graphene Rolled to Fly: Carbon Nanotube Advancements in Aerospace

Carbon nanotubes (CNTs), formed by rolling graphene sheets into cylindrical structures, have emerged as a transformative material in aerospace engineering due to their extraordinary mechanical, thermal, and electrical properties. This paper explores the latest advancements in CNT technology, focusing on their integration into aerospace applications to enhance structural performance, reduce weight, and improve efficiency. CNTs offer tensile strengths up to 100 times greater than steel while being significantly lighter, making them ideal for reinforcing composite materials used in aircraft and spacecraft. Recent innovations in chemical vapor deposition and scalable production methods have lowered costs and improved CNT quality, enabling their use in lightweight airframes, thermal management systems, and electromagnetic interference shielding. The paper also discusses ongoing challenges, such as achieving uniform dispersion in composites and ensuring cost-effective large-scale manufacturing, while highlighting real-world applications, including NASA’s use of CNT composites in space missions. By addressing these hurdles, CNTs are poised to revolutionize aerospace, contributing to more fuel-efficient, durable, and sustainable flight systems. For next-generation aircraft systems, these multipurpose CNT-based films offer lightweight, long-lasting, and high-performance alternatives to traditional materials. Despite their potential, large-scale deployment is constrained by issues like batch variability, structural impurities, and insolubility in aqueous conditions. Overall, this research emphasizes how important carbon nanotube innovation is to the development of aeronautical materials. Unlocking their full potential requires constant advancements in application-specific processing, structural customisation, and synthesis control. Future aerospace designs will be smarter, stronger, and safer because to CNTs’ potential to transform aircraft and with its multifunctionality and structures.
