Disposal and recycling of aerospace materials

24.1 Introduction

The disposal and recycling of aerospace materials is an important issue in the whole-of-life management of aircraft. The use of sustainable materials is becoming more important as the aerospace industry moves towards a ‘cradle-to-beyond the grave’ approach in the management of aircraft. Until recently, the selection of materials for aircraft structures and engines was based on cost considerations and performance requirements. Materials are selected on economic considerations such as the costs of purchase, manufacturing, assembly, and in-service maintenance. Materials are also selected on performance requirements such as stiffness, strength, toughness, fatigue life, corrosion ...
