About the Project
Aims and Objectives:
The aim of this research is to establish analytical as well as numerical models enabling us to gain further insights into the formation of interfacial bonds between polymer phases during manufacture of the overmoulded composite parts, as well as failure of the final structures under loading. The PhD candidate will have the advantage of exploiting a relatively wide range of the test results and data obtained during the course of a previous comprehensive study where the bond strength of several overmoulded specimens based on various types of engineering and high-performance polymer composites was measured.
The key objectives of the project include:
• Simulation of the interface formation during the overmoulding phase using CFD packages
• Developing FE based platforms for stress analysis and failure prediction of the overmoulded specimens using the available experimental data
• Investigating the effects of key processing variables including injection pressure, and temperature of the phases as well as thermal and rheological properties of the polymers on the model-based results, in comparison with experimental data.
• Manufacture and testing overmoulded specimens (when necessary) in collaboration with industrial partners.
Successful candidate will have the option of engaging with the world leading Aerospace partners of the Northern Ireland Advanced Composite Engineering (NIACE) centre involved in related projects, through participation in meetings and company visits.
This PhD will be carried out within the Advanced Composites Research Group (ACRG) at Queen’s University Belfast.
Key skills required for the post:
Knowledge of computational methods (structures and preferably, also fluids).
Key transferable skills that will be developed during the PhD:
Polymer composite processing, injection moulding, numerical simulation, stress analysis
