Materials for Aerospace Applications

Abstract

The substantial requirements on materials for aerospace applications are „light and reliable“, which have to be fulfilled in most cases under extreme service conditions. Therefore, specially designed materials and material systems are in use. Furthermore, joining technologies play an important role for weight reduction and reliability of components. Manufacturing technologies and characterization methods for qualifying materials and joints for aerospace applications will be discussed. Topics are: • Loading conditions for components of air- and space crafts (structures and engines) • Development of materials and material systems for specific service conditions in aerospace applications (e.g. for aero-engines, rocket engines, thermal protection shields for reentry vehicles, light weight structures for airframes, wings, and satellites) • Degradation and damage mechanisms of aerospace material systems under service conditions • Characterization and testing methods for materials and joints for aerospace applications • Concepts and methods for lifetime assessment
