The aim of this project is to propose a methodology to design composite components to conduct electrical current without sustaining unacceptable levels of thermally induced damage.  Capability to electrically couple carbon fibre composites with electrical power systems offers a route to improved electrical power density for aerospace applications.  Metallic equipment enclosures result in persistent weight penalties of at least 10 % of equipment weight. Infrastructure to maintain physical separation between electrical cables and composite structures incur a 30% weight penalty. Metallic casings and structures on aircraft form the electrical grounding and bonding network.  Conduction of electrical current through carbon fibre composite components results in localised Joule heating, which if excessive can reduce mechanical functionality of the component.  For grounding and bonding, a structure must have capability to electrical current at magnitudes and durations determined by the wider electrical power system topology. 

The co-design methodology which is the focus of this project necessitates knowledge of limitations for electrical current conduction (duration, magnitude).  During the project experimentally based correlation between different system variables (electrical, thermal and structural (including different layups, physical sizes, electrode location)), and quantified changes in mechanical properties (for example, interlaminar shear strength (ILSS)) will be investigated.  Assessment of the level of Joule heating induced damage will include non-destructive evaluation methods by applying ultrasonic scanning methods to provide qualifiable measurement of physical changes in carbon fibre composites.

The project is multidisciplinary, combining non-destructive testing, materials and electrical power systems.  It will involve a mix of experimental work, and data analysis and signal processing, within which there is opportunity to apply and explore machine learning methods.  The project will be in collaboration with Boeing and National Manufacturing Institute Scotland, providing opportunity to engage with industry and access to state of the art materials manufacturing and testing facilities. 

We are seeking a candidate who: either has graduated with BEng/MEng at Distinction or First class honours level, or is on track to do so in Summer 2027, in Electronic & Electrical Engineering, Mechanical, Aerospace, and Maritime Engineering, Computer & Electronic Systems or Physics; has a strong interest and enthusiasm for the research topic, is keen to undertake experimental work and learn the necessary skills required for this.

Please apply with covering letter or email, outlining your interest in the PhD and attach a copy of your CV, emailed to Dr Catherine Jones and Dr Ehsan Mohseni (contact details below).
