Collection description
Fibre to matrix interface properties play a fundamental role in fiber reinforced polymers damage mechanisms, contributing to the complexity of composite materials failure prediction. In the present dissertation an original micro-mechanical experimental approach, based on micro-cantilever tests, was proposed for the in-situ interface testing. The adoption of computational models, supporting the experimental campaign evidences, allowed the interface properties identification. The proposed computational models were first validated on the base of the experimental results and thus adopted to investigate the interface debonding behaviour as well as the experimental method consistency in isolate both the opening (mode I) and sliding (mode II) damage mode. An analytical approach, describing the deformation behaviour of the micro-cantilever specimens, was concurrently developed. It represented the base for the development of a leaner combined experimental-analytical approach for the interface properties identification. Its application to the experimental campaign evidences provided results perfectly in line with those numerically retrieved.
