A Bio-Inspired Lightweight Composite System for Blast and Impact Protection
Grant number: DP170100851 | Funding period: 2017 - 2020
This project aims to develop a lightweight armour system that protects structural elements from extreme loads. Every day around the world, accidental and deliberate loads cost billions of dollars in damage and loss of life. The project’s composite system can concentrate material into areas most needed under impact loads and absorb and mitigate energy under blast. The anticipated outcomes of this project should be directly applicable to designing, assessing and strengthening structures, including civilian buildings, defence structures, bridges and offshore and industrial facilities.
