The development of green and nano-enhanced composites represents a pivotal shift toward sustainable innovation in aerospace materials. Even though there are some drawbacks, there are still scopes to overcome the issues by working on them. As global priorities increasingly align with eco-conscious manufacturing, these composites are well-positioned to foster lighter, more efficient, and sustainable aircraft components. Future research should therefore focus on real-world performance validation, life cycle analyses, and scalable fabrication methods, in order to fully realize the transformative potential of these materials in aerospace engineering.
