abstract

Fibre Metal Laminates (FML) are a member of the hybrid materials family, consisting of alternating metal layers and layers of fibres embedded in a resin. Improved damage resistance and tolerance result in a significant weight and maintenance cost reduction compared to aluminium. FML also give the aircraft engineer additional design freedom, such as local tailoring of laminate properties. However, experience has shown that FML’s provide the aircraft manufacturer with many challenges as well. With increasing complexity of the structure, requirements from different disciplines within the engineering process will start to interfere, resulting in conflicts. This article discusses the current engineering process of FML fuselage panels as applied at Stork/Fokker Aerospace (FAESP). A case study is presented, clarifying the current design process and the way requirements start to interfere during the engineering process. A new approach based on Knowledge Engineering is discussed, implementing knowledge from engineers from all disciplines in an early stage of the design process. An automated design approach for FML fuselage panels is presented, using the same design parameters as the current approach. Because of the high complexity of the design, requirements start to conflict. Fulfilling all requirements with a traditional engineering approach results in an iterative and time consuming process. Automation of the design process, integrating knowledge and requirements from all disciplines, results in a fast and transparent design approach.
