Project Description

Informal enquiries should be directed to Dr HaNa Yu ().


Fibre reinforced polymer composites offer outstanding strength, stiffness and low weight, and their use is rising rapidly in various sectors such as aerospace and automotive. However composite manufacturing is challenging as it is often faced by long processing time, waste in production and limited formability for complex shapes. One way to overcome these challenges is to utilise short rather than long fibres. However current manufacturing processes handling short fibres lead a difficulty in achieving the mechanical property required.

The supervisor of this PhD project published a patent, High Performance Discontinuous Fibres (HiPerDiF)[1], aimed at overcoming these challenges. It offers one way of handling discontinuous fibres, i.e. aligning them all in one direction, leading to achieving comparable mechanical properties of continuous fibre reinforced composites.

The purpose of PhD project is to create next innovative steps in meeting industry production needs. The successful applicant will identify industry’s manufacturing needs and create a process capable of manipulating the fibre orientation and its volume content to create novel fibre architecture in composites.

It aligns well with the mechanical engineering department research strategy in University of Bath, future manufacturing for advanced materials.

The successful candidate will benefit from frequent interaction with industrial partners in the composite manufacturing sector, as well as collaborations with other major academic institutions (e.g. University of Bristol, National Composite Centre in the UK).

Applicants should hold, or expect to receive, an undergraduate Masters first class degree or MSc distinction (or non-UK equivalent) in Mechanical Engineering, Materials Science, Manufacturing or related discipline . English language entry requirements must be met at the time of application to be considered for funding, see

Formal applications should be made via the University of Bath’s online application form for a PhD in Mechanical Engineering. Please ensure that you state the full project title and lead supervisor name on the application form.
