Assessing the Life Cycle Environmental Performance and Economic Costs of Composite Materials in Certain Aircraft Structure

The aviation sector is looking to replace conventional metals for aircraft doors with composite materials due to the latter’s potentially favorable combination of mechanical properties and low weight. However, little is known about the environmental impacts and economic costs associated with the production of such composite doors. This study conducts a Life Cycle Assessment and Life Cycle Costing on an example composite aircraft door to quantify its environmental and economic impacts. In addition, uncertainty analysis has been performed to enhance the quality of the assessment.
