The present proposal of research activity considers the developments of techniques for the realization of smart multifunctional active composites by means of novel additive manufacturing processes. By active composites we mean structural components realized with composite materials with embedded sensing and actuation capabilities or, more in general capable of providing multifunctional behavior (such as combined structural and thermal properties). The realization of such components requires the embedding within structural components of circuits and electronics circuits. Thus, the research activity will consider all the layers of the additive manufacturing process. Specifically, the research will consider

- Digital Modelling
- Materials
- Manufacturing Process
- Post-processing

As results of this study a design workflow and a methodology for the additive manufacturing realization of smart composite components will be presented. The obtained results will be tested on applications coming from the world of the mechanical and aerospace engineering.

Specifically, the following test cases will be considered:

- Smart tools
- Sensorized wing
- Racecar structural parts

The considered test-cases will permit to apply the developed conceptual methodologies and to demonstrate their appeal for advanced industrial applications. Moreover, the sensorised wing will be tested in a wind-tunnel and the system will show its ability to give a real-time feedback for the environmental loads.
Similarly, smart composites will be used to build automotive structural elements (such as the suspension A-arms) in order to allow a close-loop active control on the vehicle drivetrain and suspension system. Track tests will be run on `Gajarda', the Sapienza racecar that competes within the Formula Student and Formula SAE inter-university championship.
