| Abstract Scope |
Three-dimensional architected materials overcome limitations of monolithic materials by leveraging engineered microstructures to achieve unique properties, but research has focused on maximizing stiffness and strength. In contrast, 3D-woven architectures have shown promise in sustaining large deformations while achieving compliant mechanical properties that approximate those of biological tissue.
Here, we introduce a framework for designing woven architected materials with tunable properties of benefit to tissue engineering applications. By modifying the design of these microstructures, we expand the design space and enable functionally graded architectures at micron scales, relevant to cellular scales. Using a graph-based weave topology and a microscale fabrication method, we tailor mechanical properties and apply both high-fidelity and reduced-order models to quantify nonlinear responses, including material and frictional contributions. Validated through in situ micro-tension experiments, woven materials demonstrate widely tunable stiffness, stretchability, and energy absorption. These insights enable tunable, tough materials for applications like 3D bio-scaffolds and soft sensors. |
