High-performance advanced composite materials integrating high stiffness, strength and excellent damping performance are in urgent demand in aerospace, energy, high-speed transportation and other fields. However, it is difficult for traditional damping materials to excel in both damping performance and those static mechanical properties. In contrast, the biological materials in nature achieve the coexistence of superior static and damping properties through sophisticated microstructure design. For example, suture tessellations of different length scales are widely found in biological materials such as animal skulls, woodpecker beaks, turtle shells, purslane seeds, etc.
