3D Printing of PA12 / CF Composite to Fabricate Equation‐Driven Möbius Strip Lattice for Small‐Scale Drone Frame

ABSTRACT Small‐scale drones have a bright future in agriculture. These kinds of drones require longer operational time, which is possible with reduced power consumption. The drone's weight is critical for longer operations. The lattice structure is well known for its lightweight and better strength‐to‐weight ratio. These lattices could be used to fabricate the drone frame, potentially providing lightness, a better strength‐to‐weight ratio, and reduced power consumption. The Möbius strip has a natural twist that could help distribute the load. PA12/CF lattice with predetermined stress‐concentration points (twist), fabricated from a PA12/CF for drone bodies, is very limited in the literature. First, static loading was applied, and stress–strain behavior was observed across three distinct zones, with a total energy absorption of 129 kJ/m 3 . Strengthening behavior after the elastic limit and considerable toughness before fracture was observed. Dynamic compression proved the 89% recovery after cyclic loading. FEM results showed that bending is the dominant failure mode, with the twist section as the primary failure location. Matrix yield at the material level played a major role in failure. An artificial neural network (ANN) used for surrogate model training and Pareto‐front multi‐objective optimization yielded the maximum‐modulus shape of Möbius strip lattice used in the drone frame.
