“…The life cycle assessment starts with the primary material production, i.e., aluminum ingot [18], carbon fibers (PAN-based), and epoxy resin [16,[25][26][27]. For the manufacturing process of aluminum components, roll forming was considered to be a material-efficient and, therefore, a leaner process for aluminum parts and assemblies [18,28].…”

Climate change and global warming pose great sustainability challenges to the aviation industry. Alternatives to petroleum-based fuels (hydrogen, natural gas, etc.) have emerged as promising aviation fuels for future aircraft. The present study aimed to contribute to the understanding of the impact of material selection on aviation sustainability, accounting for the type of fuel implemented and circular economy aspects. In this context, a decision support tool was introduced to aid decision-makers and relevant stakeholders to identify and select the best-performing materials that meet their defined needs and preferences, expressed through a finite set of conflicting criteria associated with ecological, economic, and circularity aspects. The proposed tool integrates life-cycle-based metrics extending to both ecological and economical dimensions and a proposed circular economy indicator (CEI) focused on the material/component level and linked to its quality characteristics, which also accounts for the quality degradation of materials which have undergone one or more recycling loops. The tool is coupled with a multi-criteria decision analysis (MCDA) methodology in order to reduce subjectivity when determining the importance of each of the considered criteria.

“…Limitations occur both for FRP materials and their manufacturing processes [6]. Taking the cradle-to-gate production of fibers and matrix materials as an example, existing data only allows an aggregated view on the energy demands while information on the properties of the materials itself, system boundaries for assessment and production scales are often ambiguous or not known [15]. Despite those shortcomings, Fig.…”

Recent years introduced process and material innovations in the design and manufacturing of lightweight body parts for larger scale manufacturing. However, lightweight materials and new manufacturing technologies often carry a higher environmental burden in earlier life cycle stages. The prospective life cycle evaluation of lightweight body parts remains to this day a challenging task. Yet, a functioning evaluation approach in early design stages is the prerequisite for integrating assessment results in engineering processes and thus allowing for a life cycle oriented decision making. The current paper aims to contribute to the goal of a prospective life cycle evaluation of fiber-reinforced lightweight body parts by improving models that enable to predict energy and material flows in the manufacturing stage. To this end, a modeling and simulation approach has been developed that integrates bottom-up process models into a process chain model. The approach is exemplarily applied on a case study of a door concept. In particular, the energy intensity of compression molding of glass fiber and carbon fiber sheet molding compounds has been analyzed and compared over the life cycle with a steel reference part.

“…This can contribute up to ∼60% of the total P-CF manufacturing energy as the synthesis involves energetically demanding multi-step polymerization of the acrylonitrile monomer. 38,43,44 To obtain the high-performance Pi-CFs necessary for widespread application, petroleum or coal tar pitch needs to be transformed into mesophase pitch. 45 This transformation instigates high ordering of aromatic molecules having both an anisotropic phase and a graphite structure.…”
