The military, bio-medical and particularly aerospace industries are continually motivated to produce materials which inhibit increased mechanical properties. This has led to advanced material design stemming from combining materials in hopes of producing a more established hybrid material which exceeds the limitations of each individual material constituent. Over the past 70 years and substantially over the last twenty years, this has led to the development of Fibre Metal Laminates (FMLs) which consist of thin layered composite/metal alloy sheets. Particularly, FMLs offer; increased impact tolerances, fatigue resistance and a higher modulus of elasticity albeit at lower densities. First and foremost, I would like to thank my advisor throughout this Thesis topic, A/Prof. Martin Veidt for his endless guidance, support and encouragement. You have provided me with the resources and knowledge to make this Thesis possible and I appreciate you giving me the opportunity to experience hybrid composite structures. In addition, I would like to also thank Kurt Mills for his time in manufacturing the hybrid samples. Furthermore, for his abilities in calibrating the measurement techniques and microscopy images. Finally, I would like to thank all other members that made the time to discuss ideas and provide clarity to tasks and results. These people include; Dr. Juan P. Torres who demonstrated the measurement techniques, Mitch Dunn who arranged the composite samples being water-jet cut and Dr. Michael Heitzmann who provided the FEM knowledge. v
