SUMMARY: Composite materials are at the heart of a fundamental evolution in aerospace and automotive design, offering light-weight responses to the low-carbon agenda. The transformative potential of composites for infrastructure – driven by their extraordinary strength- and stiffness-to-weight ratios – is as an enabling technology in three arenas key to the installation of a resilient, adaptable, low-carbon UK infrastructure: development of advanced low-carbon generation capacity (e.g. wind, wave or tidal turbines); adaptation of existing structural components for amended or extended service (e.g. bridge repair); and realisation of radical structural forms (e.g. load-bearing shells). The main hurdle that composites must overcome is concern over their durability in a 50+ year infrastructure environment. The DURACOMP project will address this by leapfrogging the conservative assumptions used in aerospace and automotive design and developing a stochastic modelling framework specifically for infrastructure composites. This will involve a three-pronged, approach based on: physical testing of structural connections and joints, and materials; computational modelling of multi-scale structures; and probability analysis of properties, loads and environmental (climate change) factors. The multi-university DURACOMP team will deliver the basis of a new paradigm for specification of composite solutions in Ground and Structural Engineering, driven by the need to prepare the UK’s infrastructure for an uncertain future.

    • Collaborating with Dr. Ana M. Girão Coelho, now with Steel Construction Institute. Ana was a Marie Curie European Intra-Fellow at Warwick University from 01/08/13 to 31/07/15, working on the project PFRPStruJoin - Structural Joints for Building Frames of Pultruded Fibre Reinforced Polymers. Aim of PFRPStruJoin was to conduct advanced and relevant research for the preparation of scientifically founded design rules for mechanically fastened joints in building frames of pultruded Fibre Reinforced Polymer (FRP) composite materials. By using Advanced computational analysis (Abaqus) she simulated the initiation and grow of key distinct modes of failure that determine the structural response in bolted joints.
