Main Methods:

Utilized molecular dynamics simulations and continuum-based finite element analysis.
Investigated seven bioinspired designs: cellular, gradient, tubular, fibrous, helicoidal, suture, and layered structures.

Main Results:

Numerical studies revealed that bioinspired carbon-based nanoscale designs can outperform conventional counterparts.
Demonstrated potential to fill gaps in Ashby charts, achieving lightweight materials with improved strength and failure strain trade-offs.

Conclusions:

Findings offer insights from biological structures for creating next-generation multifunctional architected metamaterials.
Highlights the potential of rationally designed nano-architectures for advanced material applications.
