Composites have many advantages over metals like, better global strength characteristics, higher stiffness, longer fatigue life, lower density, low thermal conductivity, better wear resistance, improved corrosion resistance, etc. However, composites have certain limitations too, for example they respond very poorly under local loading, properties highly depend on manufacturing conditions, strength characteristics vary with direction, have complex and costly manufacturing processes, formability is not easy, etc. Hence, complete elimination of metal alloys from an aircraft structure is not right. Accordingly, use of hybrid metal-composites for major part of the aircraft structure is the rational option. The uses of hybrid metal composites, wherein metal as well as composites are used for different parts of an assembly, provide great performance and durability benefits inherent to both metal alloys as well as composites. There are many areas in an aircraft structure where hybrid metal-composite may be implemented.
This project is aimed at deriving a methodology for the design of hybrid
