To achieve the goal of Net-Zero transportation, development of new composite materials is required to see greater adoption of composites. A key area that offers potential for significant weight saving is complex loaded joints such as lugs, used to connect structural components and transfer loads. A primary weakness facing traditional laminated composites in their attempt to replace metallics is the lack of through-thickness-reinforcement (TTR), leading to delamination and premature failure, particularly around pin/bolt holes.
3D woven composites offer a desirable answer through using fibre in the xyz direction, where “z” fibres carry load through-the-thickness and resist impact damage. Despite the high benefits of 3D preforms, the lack of +/-450 fibre that is necessary for complex loading inhibits its adoption. A recently awarded EPSRC project aims to address this through developing a new 3D+ multi-axial material containing fibre in all 5 key orientations, however additional TT is required to support this.
This PhD project will investigate novel methods for generating localised TTR around pinned and bolted joints. This will be achieved through the following primary objectives:
The student will be trained to gain expertise and knowledge in the areas of structural composites, testing design, and materials characterisation and analysis. In addition, the PhD researcher will travel nationally and internationally to present their findings.
Candidates with a background in mechanical/aero/materials engineering or any other related engineering field is desirable.
Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.
We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.
In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.
If the University receives a large number of applicants for the project, the following desirable criteria may be applied to shortlist applicants for interview.
The University is an equal opportunities employer and welcomes applicants from all sections of the community, particularly from those with disabilities.
Appointment will be made on merit.

Our fully funded PhD scholarships will cover tuition fees and provide a maintenance allowance of £19,237 (tbc) per annum for three years (subject to satisfactory academic performance). A Research Training Support Grant (RTSG) of £900 per annum is also available.
These scholarships, funded via the Department for the Economy (DfE) and the Vice Chancellor’s Research Scholarships (VCRS), are open to applicants worldwide, regardless of residency or domicile.
Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.
Due consideration should be given to financing your studies.
