Nacre-inspired hierarchical brick-layer architecture for enhanced acoustic-structural performance in 3D-printed continuous flax fiber reinforced composites

Key Points

• Enhanced acoustic performance compared to traditional materials highlights significant developments in design.
• Structural performance metrics show improvements, particularly in 3D-printed flax fiber composites.
• The hierarchical architecture draws inspiration from nacre, which provides both strength and flexibility.
• These innovations support further exploration of bio-inspired materials in engineering applications.
