摘要
Abstract Certain biominerals, such as sea sponges and echinoderm skeletons, display a fascinating combination of mechanical properties and adaptability due to the well‐defined structures spanning various length scales. These materials often possess high density normalized mechanical properties because they contain well‐defined pores. The density‐normalized mechanical properties of synthetic minerals are often inferior because the pores are stochastically distributed, resulting in an inhomogeneous stress distribution. The mechanical properties of synthetic materials are limited by the degree of structural and compositional control currently available fabrication methods offer. In the first part of this review, examples of structural elements nature uses to impart exceptional density normalized Young's moduli to its porous biominerals are showcased. The second part highlights recent advancements in the fabrication of bio‐informed mineral‐based composites possessing pores with diameters that span a wide range of length scales. The influence of the processing of mineral‐based composites on their structures and mechanical properties is summarized. Thereby, it is aimed at encouraging further research directed to the sustainable, energy‐efficient fabrication of synthetic lightweight yet stiff mineral‐based composites.
