Development of a model to predict conditions for optimal orientation of nanoparticles in an extrusion process, together with methods of manufacturing non-leaching pipes based on nanoclay technology. The role of the nanoparticles is to form a barrier to render the pipe non-permeable to hydrocarbons and contaminants. The orientation of nanofillers determines the effectiveness of the pipe in preventing permeation. The innovation is the process of producing layers of aligned nanoclay platelets in the pipe body reducing permeation and leaching and using a multiscale model of the nanoclay/polymer systems to predict exfoliation and orientation of the platelets. The model is used to predict conditions for optimal alignment to form a barrier layer in extruded pipes. Factors involved include polymer blend selection, nanoclay type, surface treatment, compounding and processing methods & conditions. Project deliverables were the creation of a model based on the process parameters to predict the alignment and distribution of platelets in polymers, the development of compounding processes and extrusion technology to produce dispersed, exfoliated and aligned nanocomposite layers within the polymer matrix, the development of an online monitoring system to check the distribution and morphology of the nanoclays in the matrix and the adaptation of co-extrusion dies to accommodate the new approach.

Develop an inifial specification for the turbine blades. We will develop a theorefical model for the composite structure based on conductive yarns of different impedance. Based on these models we will experimentally model the radar attenuation in the S-band and the X-band. The findings wili be validated using a DoE approach by producing small scale samples and measuring radar attenuation and comparing with theoretical findings. Based on the finding the models will be opfimised. • Flomerics - Develop and validate the initial EM modelling software solution. - Train consortium members in the use of the Flomerics software • Solent Composites -Involvement in setting the initial specification for the blades -Produce small scale composite samples • AMEC -Involvement in setting the initial specification for the blades • Pera - Modelling of the radar absorpfion of the composite structures -Testing of samples for radar attenuation (to be undertaken under sub-contract by organisation with large anechoic). Experimental invesfigafions will be undertaken using a DoE approach to determine the most appropriate yarns and conductive materials. Following a DoE approach, the yarns will be processed to give controlled conduction. The experiments will investigate co-mingled, coated and co-extruded yarns and the associated processing methods. The yarns be characterised to determine impedance and based on the findings, the materials and processes will be selected and optimised. • Oxley Threads - Develop a manufacturing process to create electrically conducfive yarns from conductive materials supplied by Hitek. • Hitek - Development and supply of the conducting materials for the conductive yarns that will later be used by Oxley Threads to produce the conducfive yarns. • Pera - Selection and modification of conductive materials and tesfing of materials for conductivity and mechanical behaviour. - Testing of conductive fibres for structure, conductivity and mechanical properties. - Testing of yams for conductivity and mechanical properties. The most appropriate conductive yarns from WP2 will be selected and base resins selected. A Jacquard 3D weaving process will be developed and optimised based on theoretical models developed in WPl. The pre-forms (with graded impedance) produced will be composites characterised for radar attenuation. Based on the results, the pre-form composite yarns and 3D structure will be optimised. • J&D Wilkie - Develop a 3D weaving technology that will allow us to create a textile structure made from yarns with different electrical conductivities that will enable us to create a textile with exponentially graded impedance through the z-axis. • Pera - Testing ofthe pre-forms for structure, mechanical behaviour, conductivity and radar attenuation. From the result of WP 1, 2 & 3, the optimal radar absorbing composite will be de signed and the 3D pre-forms will be manufactured on a lab-scale. The pre-form will be resin infused and metallic reflectors adhered to the back. The composite will be tested for radar attenuation and for mechanical performance and the composite structure (pre-form, resin and metallic reflectors) optimised. • Solent Composites - Develop a manufacturing process to enable the pre-form to be inserted into the blade mould, resin vacuum infusion of the pre-form and installation of the metallic backing sheet. - Testing ofthe blades for mechanical and other behaviour. • Hitek - Supply the conducfing materials forthe conductive yarns • Oxley Threads - Create electrically conductive yarns. . J&D Wilkie - Create textile structure. • Pera. - Testing of resin infused pre-form composites for structure, mechanical behaviour, conducfivity and radar attenuation. Fromthe result of WP 4, an optimised 3D pre-form will designed. The appropriate method of resin infusion will be determined. Tlie blade manufacturing process will be modified to allow the pre-form to be integrated during manufacture and then infused with resin to create a full scale turbine blade. The resultant blade structure will be tested and optimised for radar attenuation and mechanical properties. Tests for long term integrity will be started in this work package and may be completed after the end of the project to ensure we can achieve a 25 year useful lifetime including testing for the effects of lightening strikes. • Hitek - Supply the conducfing materials for the conducfive yarns - On-going management of long term integrity tests • Oxtey Threads - Create electrically conductive yarns • J&D Wilkie - Create textile structure. • Solent Composites - Produce full scale blade samples .

High Integrity Actuation with Embedded Intelligence for Steer-by-Wire TSB Project No: TP/5/POW/6/I/H0248K This project is concerned with the development of a low-cost intelligent actuation system for safety-critical applications and for working in harsh working environment. The overall aim is to deliver a technological breakthrough in the development of a high integrity and reliable actuation system with an enhanced safety capability of three level redundancy ( i.e. safe operation must be preserved in the presence of two major faults in the system) at low costs, through the innovative use of power electronic devices/configuration and embedded intelligence with novel fault detection and fault-tolerant control. In the event of one major critical fault, the system will be expected to maintain the normal control allowing the system to continue and complete an assignment before seeking service. If a second major fault occurs before the first one is fixed, there must be a provision to maintain safe operation (probably at reduced performance/speed) for a limited period so that there is sufficient time for access to repair. A key objective for the project is to deliver a high level of actuator integrity with the use of minimal number of major components (hence reduced costs), whereas conventional solutions of using hardware redundancies would require the use of triple actuators and associated controls which would substantially increase the costs and system complexity. The development will be focussed on exploring the inherent redundancy of PM brushless actuators (most commonly used in applications with high reliability requirements), with the aim to reduce component number and system/mechanical complexity. Key benefits include reliable and robust actuation systems, inherent redundancy and self-monitoring & control; improved efficiency; simpler mechanical configuration, and reduced component number and hence costs. The project will be developing a prototype for commercial exploitation, firstly for steer-by-wire applications in automotive industry and then followed by expansions into other safety-critical applications. This fault-tolerant technology is expected to supersede and replace either hydraulic or EM actuators in demanding applications. There is huge global market potential for steer-by-wire systems, and many spill over benefits in other safety-critical applications for highly reliable actuation.
