本研究は、エアバスA320-200、A350-900、ボーイング787-9の機体構造を対象に、材料選定がライフサイクル環境・経済性能に与える影響を評価した。Granta EduPackを用いたスクリーニングにより、金属材料と複合材料の比較を行い、金属ベースラインの方が低い内包エネルギーと気候変動影響を示し、リサイクルクレジットも大きいことを明らかにした。一方、複合材は製造負荷が高く、リサイクルが限定的である。設計初期段階での持続可能性統合のための構造的手法を提示している。
English
This study evaluates the environmental and economic performance of aircraft structural components (fuselage and wing) for Airbus A320-200, A350-900, and Boeing 787-9. Using Granta EduPack, it compares metallic and composite structures, finding that metallic baselines have lower embodied energy and climate change impact and higher recycling credits, while composites have higher production burdens and limited recovery. The paper provides a structured method for integrating sustainability into early aircraft structural design.

📄 Abstract（原文）
Material selection plays an important role in the life cycle performance of aircraft structures, especially at the conceptual design stage where major design decisions remain flexible. This study investigates the environmental and economic performance of the fuselage primary structure and the wing primary structure of the Airbus A320-200, Airbus A350-900 and the Boeing 787-9. A streamlined assessment framework was developed using the Granta EduPack Performance Index Finder and Eco Audit method. Publicly available aircraft material breakdowns, conceptual mass allocation methods and representative assumptions were used to construct component level inventories for metallic and composite structures. Material screening was carried out using performance indices derived for both strength limited and stiffness limited design cases. Candidate materials were then shortlisted from Ashby-style charts and ranked using a weighted value proposition combining mass, costs, embodied energy and climate change. The results show that material production dominates embodied energy and climate change impact, while structural material choice strongly affects end-of-life (EoL) recovery potential. Metallic baseline cases generally show lower embodied impacts and stronger recycling credits, whereas composite intensive cases show higher production burdens and more limited recovery. Re-evaluation of shortlisted substitutes indicates that selected materials can reduce energy demand and carbon emissions, although these improvements do not necessarily reduce cost. Overall, the study demonstrates a structured method for integrating sustainability into early aircraft structural design.
