A Bio-Inspired Lightweight Composite System for Blast and Impact Protection
Accidental and deliberate loads on civil and military structures, locally and internationally have claimed lives and cost governments billions of dollars worldwide. The key challenge is to develop a lightweight high performance protective structure that exhibits superior strength and toughness simultaneously, which are typically mutually exclusive in traditional engineering materials. Mimicking natural structures (such as turtle shells, pearl oysters, porcupine quills etc.), which have optimised their armouring systems over millions of years of evolution to counter predator attacks, could lead to efficiently lightweight engineering structures with improved mechanical responses to extreme loadings such as blast and impact.
The project aims to develop a bio-inspired multi-functional lightweight and modular negative Poisson’s ratio composite panel system that can concentrate material into areas most needed under impact loads, absorb and mitigate energy under blast, and provide an anchoring effect that prevents hazardous fragments from flying out of the system.
