About the project
This PhD project investigates the design and durability of advanced composites under cryogenic conditions, focusing on fibre–matrix interfaces, thermal mismatch, microcracking and fracture mechanisms. Through experimental characterisation and damage assessment, it aims to establish relationships between material architecture, damage evolution and structural integrity, enabling safer, lightweight composite structures for aerospace applications.
Achieving Net Zero aviation requires disruptive technologies for lightweight, hydrogen-powered aircraft. Advanced composite materials are crucial to this transition, particularly for liquid hydrogen storage at −253°C. However, extreme cryogenic environments introduce significant challenges associated with thermal mismatch, fibre–matrix interfacial degradation, microcracking and progressive damage evolution.
This PhD project aims to develop a fundamental understanding of the mechanisms governing the structural integrity and durability of advanced fibre-reinforced polymer composites under cryogenic conditions, supporting the development of safer and lighter hydrogen storage systems.
The research will combine experimental fracture mechanics, advanced imaging and Artificial Intelligence (AI) to investigate damage initiation and evolution across multiple length scales. Particular attention will be devoted to fibre–matrix interfaces, matrix cracking, delamination and the effects of thermal cycling on mechanical performance.
A central innovation will be the application of AI-driven image analysis to high-resolution microscopy and X-ray computed tomography, enabling automated damage detection, microcrack segmentation, quantitative microstructural characterisation and identification of relationships between material architecture and damage evolution.
The resulting experimental and imaging datasets will support the development of predictive approaches linking microstructural damage to macroscopic structural performance, informing material selection and interface engineering strategies.
Ultimately, the project will establish new knowledge and AI-enabled methodologies for designing damage-tolerant cryogenic composites, accelerating the development of reliable lightweight hydrogen storage technologies and contributing directly to the transition towards Net Zero aerospace transportation.
