The project aims to achieve the following objectives:
CIRA will develop numerical simulation methods for the diagnosis and the prognosis of structural health of damaged composite structures by impact. An integrated system inclusive of methods and algorithms and also of the associated hardware based on piezo and fiber optics technologies will be designed and assembled. Based on the integrated system developed, new design criteria will be defined aimed at reducing structural weight respect to the current design approach.
CIRA will develop out-of-autoclave processes starting from basic technologies as prepreg and liquid infusion, and materials, in order to obtain a reduction of costs and an increase in the structural performance of components compared to conventional processes. The validation will be performed in the industrial environment in order to acquire data useful to the validation of cost model and for the validation of both processes.
The validation process is based on a series of technological demonstrators with complexity gradually increasing, up to structural sections in real scale or otherwise representative of real components. The choice made in the project is to aim to a technology demonstrator representative of a high aspect ratio wing section of a RPAS category in order to obtain improved aerostructural performance respect to "long endurance" requirement.
