This PhD research opportunity focuses on the pioneering development of self-healing three-dimensional metal-composite hybrid materials. The innovative approach leverages through-thickness reinforcement to integrate metallic elements within the composite structure. These metallic elements act as a targeted heat source, activating re-processable matrices such as thermoplastics or vitrimers. Funded by EPSRC and Cranfield University, this project aligns with the Royal Academy of Engineering Research Fellowship initiative titled "Multifunctional Z-Direction Hybridisation of Composites," in collaboration with the University of Southampton, Laser Additive Solutions, and the National Composites Centre.

In industries reliant on high-performance composites, such as autonomous vehicles and offshore wind turbines, maintenance and repair are often arduous and costly. Operational wear and damage from isolated events like impacts can substantially compromise material integrity. Additionally, the challenge of recycling these composites at the end of their life cycle further underscores the need for innovative solutions.

This project uniquely addresses these challenges by integrating large-diameter (>1 mm) metallic hybridising elements into composite laminates, enabling intrinsic self-healing capabilities. These elements act as a localised heat source, eliminating the need for external heating apparatus during repair processes. However, to fully harness the potential of this technology for repair and recycling purposes, it is imperative to bridge the academic knowledge gap concerning the thermo-mechanical interaction between metallic TT-elements and composite constituents.

Benefiting from the state-of-the-art facilities at Cranfield University's Composites and Advanced Materials Centre, this project will encompass manufacturing process development, material parameter optimisation through finite-element simulation, and rigorous testing and validation of functionality and performance. By leveraging through-thickness reinforcement, this initiative promises a paradigm shift in composite utilisation, extending its applicability to recycling and repair scenarios. The resultant increase in structural longevity and durability will yield substantial savings in maintenance, repair, and replacement costs.

The candidate will actively engage in knowledge exchange activities, participating in manufacturing and testing trials, and attending industry conferences such as the International Conference on Composite Materials.

This role presents an unparalleled opportunity for the candidate to develop practical manufacturing skills and proficiency in process/performance simulation, with a focus on through-thickness reinforcement—an area of high demand within the UK's composite industry. Furthermore, involvement in mentoring MSc students will cultivate invaluable people management and learning support skills, enhancing the candidate's overall professional development.
