Bio-inspired design to overcome strength-toughness trade-off of composites

点击翻译按钮获取中文摘要

This project aims to develop nature-inspired metal composites of exceptional mechanical properties that push the known boundaries of engineering materials. The design utilises a phase transforming metal to transcribe the attributes of biopolymers in nacre to harness the exceptional intrinsic strength of interatomic bonds at atomic scale and to devise adaptive ability for load redistribution for toughness at the macroscopic scale. The expected outcomes are an innovative bio-inspired material design strategy that may underpin the creation of many novel high-performance structural composites of unmatched strength and toughness properties, and potential to support new applications and to value-add Australia’s materials manufacturing industry.
