Experimental analysis shows improved energy absorption in origami honeycomb structures, indicating potential in advanced applications.

The origami honeycomb structures demonstrated enhanced energy absorption properties, outperforming traditional designs.
Characterization revealed a tensile strength improvement due to the incorporation of Fe 3 O 4 nanoparticles, achieving over 99% shape fixity.
Increasing cell spacing and folding angles enhances energy absorption significantly, reaching a specific energy absorption of 0.39 J/g.
Under cyclic loading, the structure retained 21.22% of its energy absorption capacity, suggesting strong repeatable performance.

Zhang et al. (2025) studied this question.
