Modular design of curved beam-based recyclable architected materials

Area of Science:

• Materials Science
• Mechanical Engineering
• Sustainable Manufacturing

Background:

• Architected materials offer advanced properties but lack recyclability and adaptability.
• Current materials are irreversibly designed, limiting their use in dynamic environments.
• Need for sustainable and reconfigurable material solutions is growing.

Purpose of the Study:

• To present a modular design strategy for recyclable architected materials.
• To develop hierarchical modules for creating complex shapes from curved beams and magnets.
• To demonstrate the in-situ recycling and repurposing capabilities of these materials.

Main Methods:

• Numerical analyses and physical prototyping of arc-serpentine curved beams (ASCBs).
• Development of hierarchical modules based on ASCBs for diverse geometries.
• Integration of magnets for enabling material recycling and reconfiguration.

Main Results:

• Systematic investigation of the mechanical properties of ASCBs.
• Successful construction of complex curved surfaces using hierarchical modules.
• Demonstration of in-situ recycling for sheet materials, bulk materials with tunable stiffness, and packaging.

Conclusions:

• The modular design strategy enables the creation of recyclable and adaptable architected materials.
• The developed materials can be reconfigured into various forms and functionalities.
• This approach enhances material flexibility for multifunctional applications, especially in resource-limited settings.
