I am working on the application of self-healing to industrially relevant structural features. This implies different challenges on which I am working. The most important design restriction is that the introduction of the healing feature, e.g. vascular network or microcapsules, does not affect the global mechanical properties of the structural feature. In addition, the propagating damage under static, fatigue or impact conditions has to be controlled and redirected into the predefined healing areas.
I am currently working on the redirection and healing of fatigue damage within skin stiffener debond specimens which mimic the stress-state of a stringer configuration. With the help of interleaves I am redirecting the delaminations into a vascular network through which a dye penetrant for damage visualisation or a low viscosity healing agent can be injected.
Before starting the ACCIS DTC programme in 2011, I worked for 2.5 years at Applus+ LGAI as test leader for mechanical testing for the aeronautical sector. In 2008 I graduated in European Materials Science Engineering (MSc) at the Universitat Politècnica de Catalunya (Spain) and the Institut National Polytechnic de Lorraine (France) and 2009 in Industrial Engineering by the Universitat Politècnica de Catalunya (Spain). I have been awarded in 2011 the scholarship from “Obra Social La Caixa”.
