PhD Studentship - Design and Optimisation of Liquid Resin Injection Strategy for Composite Repair

Imperial College London - Department of Aeronautics

Qualification Type: PhD
Location: London
Funding for: UK Students, EU Students
Funding amount: £16,553 + Tax-free stipend per annum
Hours: Full Time
Placed On: 9th August 2018
Expires: 7th November 2018

Tax-free stipend of minimum £16,553 per annum

Overview:

This project aims at devising an efficient resin injection procedure for composite repair through computer simulation. The key components are the choice of an appropriate resin or mixture of resin and nano-particles, the development of a CFD solver for multi-phase flow that incorporates free-surface modelling, complex resin rheology, and surface tension, the reconstruction of the geometry of the cavity created by cracks and delamination, and the coupling of an optimization procedure and the CFD solver to devise an optimal injection and venting configuration at a temperature that achieves complete filling of the cavity without trapped air bubbles or dry spots in a cost-effective manner. The ultimate goal is to employ this “virtual” injection process to ensure complete infiltration of the cavity and achieve high repair efficiencies.

The objectives of this project reflect the novel, highly exciting nature and multidisciplinary elements of this project. This project will be co-supervised by Dr Joaquim Peiro (CFD modelling) and Dr Koon-Yang Lee (Formulation engineering). Prof. Paul Robinson (Delamination and mechanical testing of polymer matrix composites) will be a co-investigator.

Pre-requisites:

Candidates should have, or expect to obtain, a strong undergraduate degree in a quantitative discipline, e.g. a 1st Class degree in Physics, Computer Science, Aeronautics, Civil, Chemical, Mechanical Engineering or Mathematics. Programming experience in C++, C, and/or Python is required. The candidate should also have an interest in fluid dynamics and aerospace applications. Familiarity with CFD packages such as OpenFoam, Gerris or StarCCM+ is highly desirable. The candidate is also expected to perform some basic experimental work for the purposes of validating the developed models.

Apply:

To apply for the position please send a cover letter, and CV to Dr Joaquim Peiro (j.peiro@imperial.ac.uk) with the subject line ‘PhD Studentship - Design and optimisation of nano-modified liquid resin injection strategy for maximum composite repair efficiency.’

Closing date for applications: Open until filled

Start Date: 1st October 2018
