Carbon fibre drone structures boost flight time by 33% with lighter, stronger design

Researchers at Seoul National University developed a new method for building carbon fibre structures that are as strong as aluminum but weigh 100 times less. The structures use a continuous carbon fibre lattice created through a 3D node winding process, removing weak points found in layered or assembled composites. In drone tests, the design increased flight time by 33% due to the weight savings. The implications go beyond drones. The same approach could reduce energy use in aerospace, automotive, and robotics by cutting structural weight without sacrificing strength. The research was published in Nature Communications and shows a practical path to lighter, more efficient vehicles and machines. For industries trying to lower emissions, lighter components mean less energy needed for movement, which directly cuts fuel or battery consumption.
