Abstract Origami tube (OT) has attracted significant attention in the realm of thin‐walled structures owing to their remarkable energy‐absorption capabilities. Nevertheless, deformation modes, particularly buckling, present considerable stability challenges. In this research, we introduce a novel corrugated structure enhance energy absorption and stabilize mode OT. The origami (COT) was manufactured using high‐specific modulus, high‐strength, lightweight short carbon fiber‐reinforced nylon via 3D printing, followed by axial quasi‐static compression tests. findings demonstrate that incorporation corrugations COT greatly stabilizes deformation, boosting 21.3% compared OT reducing peak crashworthiness force up 21.37%. Finite element analysis accurately replicates experimental performance COT, affirming feasibility simulation. Optimization Non‐dominated Sorting Genetic Algorithm II (NSGA‐II) produced Pareto front, revealing trade‐offs among various indicators offering flexible design approach meet diverse requirements. This study provides valuable insights guidance for lightweight, structures. Highlights effectively significantly improves reduces initial multi‐objective optimization variety solutions different needs.
