| Abstract | In the present work a methodology for optimizing composite aircraft structures with regard to quality, cost and environmental footprint is presented. The proposed methodology was implemented for the case of the canopy of the Twin Star Helicopter by involving different materials (carbon fiber reinforced thermosetting and carbon fiber reinforced thermoplastic composites) and manufacturing processes (autoclave, RTM and CDF). The environmental and financial analysis exhibited that when involving thermoplastic composite materials scenarios, the material of choice is impaired from both the high embodied energy and raw material cost of PEEK. However, potential benefits from thermoplastic composites like recyclability and reusability as well as the high production rates that they offer were not taken into account. This underlines the need to include potential reusing and recycling applications of the composites, as well as circular economy considerations to the criteria for designing an aircraft structure, selecting the material for this structure and finally manufacturing the structure. |
