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 introduce aerospace materials and their applications in different aerospace systems. It equips students regarding the selection of the materials and their applications in various systems. It attempts to cover the entire field of aerospace materials in a condensed fashion with emphasis on aerospace structures and propulsion systems applications. At the end of this course, students are expected to achieve a comprehensive idea about how to select the best available material in every case in the field of aerospace engineering.
