Advances in aerospace systems such as aircraft, spacecraft, and launch vehicles are strongly dependent on advances in materials and processing technologies. This course aims to present aerospace materials and their applications in different aerospace systems as well as manufacturing technologies. It introduces students regarding the selection of the materials and their applications in aircraft, spacecraft, launch vehicles, propulsion systems, and power systems. It attempts to cover the entire field of aerospace materials in a condensed fashion. The course is arranged such that the student is first introduced to basic aerospace materials and their characteristics, followed by how to select the best material for a given application. In this course, aerospace structures and propulsion systems applications are emphasized. These are by far the most demanding applications from a materials perspective. Specific strength and stiffness, factors of safety, and damage tolerance are emphasized as important considerations. At the end of this course, students are expected to achieve a comprehensive understanding about how to select the best available material in every case in the field of aerospace engineering.
