Riassunto analitico
One of the main obstacles to the composite materials spread is the manufacturing cost. Then composite production cost estimation model is needed in the design of a composite wing. In this thesis first is drawn a focus over the most widespread technologies available in the composites manufacturing field. Then is shown a cost model, based on a modular construction, suitable for the analysis of different case studies. This model is used to assess the production cost of one wing built from scratch with two different methodologies. The first configuration consists in prepreg laid with hand lay-up and cured in autoclave, the second in dry fiber laid with AFP, liquid infusion of resin and cure in oven. The aim of this thesis is to evaluate the most cost-effective configuration and the main parameters affecting the production cost.
