碳纤维增强复合材料(CFRP)在航空航天工业中有着广泛的应用。然而，制造碳足迹和直接成本是进一步在航空航天结构中采用CFRP的障碍。为此，本文提出了碳纤维增强塑料生产的生态经济综合评价模型。本文基于生命周期评价(LCA)和生命周期成本分析(LCCA)建立了生态效率评价模型(EEAM)。EEAM是一种基于作业的自下而上的纤维增强聚合物(FRP)制造过程决策支持工具。本文讨论了作为LOCOMACHS项目的一部分，为现代商用飞机制造CFRP翼肋的案例研究。EEAM的生态研究结果表明，采用高压釜内单线注射(SLI)技术制造CFRP热固性翼肋的碳足迹约为每公斤CFRP 109公斤二氧化碳当量。此外，纤维材料是碳足迹的主要贡献者。另一方面，经济评估表明，所研究的肋骨的直接制造成本约为584(原文如此)/公斤。在这些结果中，人工劳动占直接成本的49%，而纤维和基质补偿了约35%。作为一种基于作业的评估模型，EEAM引导决策者走向可持续的直接应用。结论是，直接应用于减少纤维废物对生态效益两个方面都是有益的。减少能源消耗对生态有益，而减少劳动力工作则与成本相关。在航空航天工业中，生态高效的直接应用显然有潜力同时满足这两个方面。(C)2018年作者。爱思唯尔·马森公司出版。这是一篇基于CC by License(http://creativecommons.orgilicensesiby/4.0/).的开放获取文章
Carbon fiber reinforced polymers (CFRP) are frequently used in aerospace industry. However, the manufacturing carbon footprint and direct cost are obstacles in the way of adopting CFRP in further aerospace structures. Therefore, the development of a combined ecological and economic assessment model for CFRP manufacturing is demonstrated in this paper. This model illuminates the proper developments for the decision-makers.In this work, the eco-efficiency assessment model (EEAM) is developed based on life cycle assessment (LCA) and life cycle cost analysis (LCCA). EEAM is an activity-based bottom-up decision support tool for the manufacturing process of fiber reinforced polymer (FRP). This paper discuses a case study of manufacturing CFRP wing ribs for a modern commercial aircraft as a part of the project LOCOMACHS. Ecological results of EEAM conclude that the carbon footprint of manufacturing wing rib made of CFRP thermoset by the technique of in-autoclave single-line-injection (SLI) is around 109 kg CO2-equivalent for each kg of CFRP. Moreover, fiber material is the main contributor in this carbon footprint. On the other hand, the economic assessment shows that the studied rib has a direct manufacturing cost of about 584 (sic)/kg. In these results, labor work dominates the direct cost with 49%, while fiber and matrix compensate about 35%.As an activity-based assessment model, EEAM guides the decision-makers toward sustainable direct applications. It is concluded that direct applications for fiber waste reduction are beneficial for both eco-efficiency aspects. Energy consumption reduction is ecologically beneficial, while labor work reduction on the other hand is cost relevant. In aerospace industry, there is a clear potential for eco-efficient direct applications that satisfy both aspects. (C) 2018 The Authors. Published by Elsevier Masson SAS.
