Bioinspired multilayer barriers of 3D-printed lunar regolith simulant-based geopolymers for mechanical and thermal protection

Key Points

• Enhanced thermal protection is achieved through multilayer barriers made from lunar regolith-based geopolymers.
• Mechanical strength tests demonstrated significant improvements over traditional materials, with values exceeding 50 MPa in some cases.
• Using 3D-printing technology, the design mimics natural barriers, providing unique protective features for harsh environments.
• These findings suggest that such materials could be critical for future lunar constructions, potentially revolutionizing space habitat technology.
