Applications accepted all year round

Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project.

The PhD will be based in the School of Mechanical and Design Engineering  and will be supervised by Dr Khaled Giasin and Dr Antigoni Barouni.

The work on this project could involve:

  • Experimental analysis on the machinability of GLARE® fibre metal laminates and its constituents S2/FM94 glass fibre composite and Al2024 aluminium alloy.
  • To investigate the effect of abrasive water jet cutting process parameters on the hole quality of GLARE® fibre metal laminates and its constituents.
  • Experimental investigation of the effect of cutting parameters on the microstructure evolution and defects formation due the abrasive water jet cutting process.
GLARE® (Glass Aluminium Reinforced Epoxy) laminate is a hybrid composite metal material currently used in the upper fuselage of commercial aircrafts. The material is made from thin aluminium sheets and glass fibre layers stacked together in alternating sequence and bonded using an adhesive epoxy. The material usual requires machining processes such as drilling and milling for riveting and assembly purposes. The machinability of GLARE® structures governs the longevity and structural integrity of aircraft during its service time. Conventional machining such as drilling for hole making has been the common method for riveting. However, the process comes at an expense of increased delamination and thermal damage in the composite layers. In addition, burr formations and sharp edges which promote for crack propagation in the material. An alternative is to use a non-contact machining technique known as abrasive water jet cutting process. The process involves using small abrasives mixed with water and applied at high pressure removing the material. The process does not involve mechanical contact between the cutting tool and the workpiece similar to conventional machining processes, therefore, the cutting forces applied on the material are negligible, while the thermal effects are completely mitigated. In addition, the use of water means that thermal stresses and damage in the material are eliminated. However, the composite layers in GLARE® will be prone to moisture absorption which will reduce the mechanical properties of the material. Therefore, it is important to optimise the abrasive water jet cutting to reduce moisture absorption and maintain excellent hole quality similar or better than that produced using conventional drilling process. It is also important to understand how the AWJC process influence GLARE® constituents (i.e. metal and composite) separately to better understand the best approach to machine GLARE laminates®. The current research will investigate the effect of cutting parameters using water jet cutting process on the final hole quality of GLARE® laminate and its constituents. This research will also study the effect of cutting parameters on the microstructure evolution and defects formation in those materials and optimise the process parameters for optimum hole quality.
