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 Lecturer in the Department of Civil Engineering and GeoSciences at the University of Newcastle-upon-Tyne. Ana was a Marie Curie European Intra-Fellow at Warwick University from 08/2013 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 Adavanced computational analysis (Abaqus) she simulated the initiation and grow of key distinct modes of failure that determine the structural response in bolted joints.

Publications co-authored by Toby Mottram
Commenatary to DSc thesis that delevlops my research in context of its contribution to engineering knowledge and scientific understanding.
Toby Mottam was the PI of a programme of research work (2010-14) with two Research Fellows (Dr Jawed Qureshi & Dr Behrouz Zafari) and PhD graduate (Dr Navroop Matharu). Publications from this project are continuing to be published and written.The objectives of this EPSRC project had been to:
- to develop a test methodology for the determination of pin-bearing strength, and to characterise this key strength property required for the design of bolted connections with FRP shapes.
- to complete a series of plate-to-plate tests that characterise the resistance of bolted connections of pultruded material, having details that correspond to practice, and which, by addressing current knowledge gaps, identified by the PI from drafting a ASCE ‘code of practice’, shall lead the research team to propose new or improved design guidance that is required for a structural Eurocode and that will reduce the risk of failure.
- to conduct and evaluate a programme of new tests on sub-assembly specimens to characterise bolted connections for bracing members and frame connections for simple construction, for both serviceability (static and fatigue) and ultimate limit states, so that we can understand their structural limitations for code writing.
- to develop and characterise a new mechanical fastener that shall give slip (and fatigue) resistant connections and can be used with FRP shapes to fabricate larger built-up members than present and, with appropriate connection components, could allow joint details to provide stiffness and strength properties for bridge engineering.
- to use a critical evaluation of the targeted test results to either revise or modify current design provisions so that the risk of structural failure is minimised as we strive for minimum weight structures for sustainable construction.
Startlink Lightweight Building System (for low cost housing) (Project ended July 2012 and the first house was executed on land with Larkfleet Homes at Bourne, Lincolnshire.)
Toby Mottam was the PI of a programme of work with PhD graduate Dr Behrouz Zafari) for the £1.3m project "Startlink lightweight building system", sponsored by the UK Government (Technology Strategy Board) and industrial partners, including Exel Composites, OCS Structural Plastics, Larkfleet House and Costain. The consortium has developed an energy-efficient, low-cost housing by developing a family of lightweight pultruded fibre reinforced polymer with integrated off-site assembly techniques. Using thin or core-filled profiles to reduce material cost, the consortium has engineered a system without th need for conventional house building components. In June 2012 the consortium built a two-storey, three-bed, low-cost house that automatically meets Passivhaus standards. Designed for buildability and adaptability, the Startlink system will avoid all site waste and require no skilled labour, concrete or wet trades. Water saving measures and flood resistance is integrated into the building design.
