Composite Sandwiches are a special class of composite materials fabricated with a combination of fiber reinforced panel skins and a low-density inner core, combining structural performance to lightweight, which are increasingly used in construction, automotive, aerospace, wind energy, sport and leisure sectors. The market is valued USD 1.6 billions with a CAGR of 8% in the next 5 years. One of the main drawbacks of this class of materials consist in their stiffness and difficulty in joining together different parts, which imply the need to produce monolithic components, increasing enormously costs and complexity of realization, transport and mounting. CoRe has developed and patented MadFlex: an innovative composite sandwich design and production process, which makes the panel flexible (even rollable) on the one side and rigid/crushproof on the other, at comparable cost and with the same production facilities. The feasibility study allowed to validate the technical feasibility selecting and analysing the use cases to be implemented and tested in aerospace and construction, identifying specs and functionalities, defining material design and production process to optimize timing and costs. In addition, the business opportunity was analysed by defining the business model, selecting the manufacturers for the future production for the first applications. The market was analysed and the Business Plan and Implementation Plan to reach the market was defined.
