Riassunto analitico
The current Master’s thesis is the outcome of the internship activity performed in the R&D department of YCOM, company specialized in the design and manufacturing of composite components, mainly for high-end motorsport applications.
The aim of this work is to investigate and compare different installation techniques of FBGs sensors in carbon fibre reinforced polymer components either embedding them within the part or bonding the sensors on its external surface.
The idea at the basis of the research is to establish the necessary know how in order to understand the feasibility of developing a structural health monitoring system, similarly to what is done in aircraft wings, to be equipped on racing cars, where fibre optic sensors are still little used, to control their well-functioning both during tests and races fulfilling the motorsport requirements of lightness, compactness and reliability and dealing with the need of performing measurements in inconvenient points. Such a system would be beneficial to monitor and increase the structural efficiency with a view to pursue a performance enhancement, but also in terms of safety avoiding unexpected components failures.
In the experimental phase of the work, different laminae specimens have been preliminary tested under bending solicitations to simulate different sensors integration techniques and to understand what method to use in the last test performed: the push-off of a Formula 4 front nose.
