Developments in advanced manufacturing and material fabrication technologies have promoted a trend towards using smart and lightweight composite panels in the manufacturing and construction industry. Lightweight composite panels provide efficient systems, offering high stiffness-to-weight ratios and high strength-to-weight ratios. These composite panels can potentially be used in many different applications such as in the automotive, aerospace, and civil construction industries. 

The overarching aim of this project is to develop an innovative auxetic composite system for significantly enhancing the resistance of critical structural elements to extreme loads. The basic idea is to utilise various combinations of the materials and optimise their geometries, proportions and topological order to tailor the composite meta-material for its intended application.
