Design and Optimization of Cuttlebone-Inspired Cellular Materials Using Turing Systems

This proposal aims to develop a computational framework for designing and optimizing new materials inspired by the cuttlebone--the internal shell of the cuttlefish--for use in space exploration. These materials are intended to be lightweight yet strong, capable of absorbing impact energy, and effective at dampening sound and vibrations, addressing key challenges in spacecraft construction and astronaut safety. By mimicking the cuttlebone's unique hierarchical structure, the project seeks to create multifunctional materials that can perform reliably under the extreme conditions of space. To achieve this, the research will extend Turing reaction-diffusion systems to three dimensions to generate 3D-printable models of cuttlebone-like structures with controllable features such as cell wall curvature and network complexity. Numerical modeling will investigate how these geometric characteristics affect mechanical stiffness and acoustic properties. The models will be validated through mechanical and acoustic experiments on prototypes fabricated using additive manufacturing. Additionally, a machine learning-based inverse design framework will be developed to efficiently optimize these materials for specific performance criteria required in space applications. The significance of this work lies in its potential to provide NASA with advanced materials that meet multiple critical requirements simultaneously, such as reduced weight, increased strength, and enhanced energy and sound absorption. By addressing current limitations in material design for space technology, the project aligns with NASA's goals of advancing space exploration through innovative engineering solutions. The outcomes could significantly impact spacecraft design, habitat construction, and equipment protection, contributing to safer and more efficient future missions.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
