Design Principles

"Abstract hierarchical design principles from natural composites to engineer advanced material performance."

This research offers a novel approach to material design by focusing on fundamental structural principles rather than direct compositional mimicry. This allows for the creation of advanced composite materials with tailored mechanical and functional performance for demanding applications.

What This Means for Your Design

Scientists looked at how strong natural materials like bone are made, not by copying the exact materials, but by copying the way they are layered and structured. They used this idea to make a new type of gel that is much stronger and tougher, and can be 3D printed.
