Overview

This project will develop ground breaking optimisation software that will enable the development of sustainable plastic packaging, materials and designs for the plastic bottle industry, an industry that has a global worth of £129billion and is manufacturing bottles at a rate of 1million/min. The impact will be realised throughout the bottle packaging supply chain enabling bio-based material suppliers to tailor their properties, bottle manufacturers the ability to process their material efficiently and brand owners the ability to design innovative sustainable packaging with the optimum amount of material to achieve the required mechanical/barrier properties. The most common process for manufacturing plastic bottles is Stretch Blow Moulding (SBM), which is primarily used to manufacture polyethylene terephthalate (PET) bottles. SBM begins with injection moulding of a test tube like specimen known as a preform that is subsequently re-heated to enable it to be soft enough to be formed into a mould by a combination of axial stretching by a stretch rod and radial stretching by internal air pressure. The main challenge for manufacturers is to produce containers with as little material as possible but still meet in-service performance requirements such as top load and barrier resistance (O2/CO2). The industry relies heavily on empirical knowledge which is inefficient, especially when new materials or blends with bio-plastics or recycled plastics are introduced. To facilitate the uptake of these materials there is an imperative to move towards a more scientific approach where material properties are measured, modelled and used in process simulations.

The project will focus on the development of innovative state of the art software that will enable packaging to be designed and manufactured with just the right amount of material. It will automate the design process for preforms and bottles for the ISBM process enabling a faster uptake of new materials and designs incorporating more recycled content. Aim: To develop an automated simulation design tool that will enable packaging to be optimally designed with reduced weight and/or sustainable materials. With the advent of biomaterials and the huge demand in the use of Recycled PET (RPET)(PlasticsToday, 2020) both of which will change the design rules for containers and significantly narrow the process window, companies that do not use this tool will be left behind if they stick to traditional trial and error methods.
The technical objectives are
1.To identify the critical parameters influencing design and setup a parametrised simulation of SBM.
2.To evaluate different optimisation approaches most appropriate for SBM simulation e.g. surrogate modelling vs direct iterative model.
3.To develop a knowledge base and a corresponding mathematical model of the behaviour of RPET and PEF.
4: To develop a case study to demonstrate and validate the capability of the software to optimise performs for PET, RPET and PEF.

Learning Outcomes

Course structure

You will carry out leading research under the guidance of your supervisory team. A full time student will normally complete in three years (up to a maximum of four), or part time over six years (up to a maximum of eight).

Research will usually be in one of the key, interlinked research themes in the School, and the subtopics they cover, include:-

Advanced Manufacturing and Processing - cost modelling, ergonomics, intelligent control, laser processing, life cycle analysis, material characterisation, mechatronics, parallel kinematic machines, polymer processing, robotics and ultra-precision manufacturing.

Future Aircraft - aero engines, aerodynamics, aeroelasticity, aircraft operations, design and analysis, optimisation and structural testing

Composite Materials and Structures -damage mechanics and crashworthiness, material characterisation, multifunctional composites and nano-enhanced composites

Simulation Technologies - FEA/CFD/EFG/DES/MD, kinematic modelling, meshing, multiscale/Multiphysics, optimisation, simulation intent, systems modelling, uncertainty quantification, virtual testing and design visual analytics and big data

Clean Energy - biofuels, catalysis, life cycle assessment, power systems, turbomachinery and waste management

Biomaterials and Biomechanics - biomimetics, material characterisation, mechanobiology and medical devices.

Also, over the course of study, you can attend postgraduate skills training organised by the Graduate School, or other internal and external training courses organised through your supervisor.

Entrance requirements

Graduate
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.

International Students

For information on international qualification equivalents, please check the specific information for your country.

English Language Requirements

Evidence of an IELTS* score of 6.0, with not less than 5.5 in any component (*taken within the last 2 years) is required.

International students wishing to apply to Queen's University Belfast (and for whom English is not their first language), must be able to demonstrate their proficiency in English in order to benefit fully from their course of study or research. Non-EEA nationals must also satisfy UK Visas and Immigration (UKVI) immigration requirements for English language for visa purposes.

For more information on English Language requirements for EEA and non-EEA nationals see: www.qub.ac.uk/EnglishLanguageReqs.

If you need to improve your English language skills before you enter this degree programme, INTO Queen's University Belfast offers a range of English language courses. These intensive and flexible courses are designed to improve your English ability for admission to this degree.

As a result of the COVID-19 pandemic, we will be offering Academic English and Pre-sessional courses online only from June to September 2020.

  • Academic English: an intensive English language and study skills course for successful university study at degree level
  • Pre-sessional English: a short intensive academic English course for students starting a degree programme at Queen's University Belfast and who need to improve their English.
