In the UK, glass fibre reinforced plastic (GFRP) contributes to 75,000 tons end of life waste in addition to 6,200 tons production waste. Because 90% of the UK’s FRP currently goes to landfill, the development of recycling solutions for composites is necessary. This is also due to the recent adoption of strict environmental legislation (such as the EU’s End of Life Vehicles Directive which aims to reduce the automotive waste disposed in landfill by setting targets for re-use, recycling and recovery of materials). This has also led to increased restrictions and costs of landfill composite disposal (Composite in Manufacturing, CIM December 2019, pp 59). On the other hand, the use of composite materials is considerably rising in many industries including aerospace, automotive, sports and medical equipment. Polymeric composites, such as CFRPs and GFRPs, are typically manufacturing by laying up pre-impregnated sheets and hence machining processes are necessary to achieve the required geometrical & dimensional accuracy and create features such as holes for assembly.
This project aims to critically investigate different methods of recycling/reuse the composite waste (either as production waste or end of life waste) in order to develop methods for manufacturing functionalised construction structures entirely/partially made from waste. The project is experimentally based and will include the use of equipment such as 3D printers, CNC machining centre, optical and electron microscopy. The project will also create an advanced computer model using ABAQUS to investigate the structural behaviour of GFRP and CFRP composite structures made from recycled materials. The models will be validated using experimental results and then will be used in a detailed parametric study. Finally, a new set of design equations based experimental and numerical studies will be developed to determine the structural capacities GFRP and CFRP composite structures made of recycling materials.
The principal supervisor for this project is Dr Islam Shyha. The second and third supervisors will be Dr Brabha Nagaratnam and Dr Keerthan Poologanthan.
