The PhD thesis “Micromechanical modelling of hybrid unidirectional composite materials under fibre tensile loading” has been presented by José Manuel Guerrero

The AMADE group is proud to congratulate José Manuel Guerrero for having achieved this PhD degree after the successful defence of his dissertation in the conference hall of the Polytechnic School of the University of Girona last 7th February.

His work has focused on an efficient micromechanical model for predicting the tensile failure process in hybrid and non-hybrid unidirectional Fibre Reinforced Polymers (FRP) under fibre tensile loading. In this framework, the influence of several parameters on the tensile response and failure development in hybrid composites has been investigated. Overall, results have showed that the model captures qualitatively well the tensile failure and damage development in hybrid and non-hybrid composite materials. Moreover, adding matrix yielding and dynamic effects into the model allows to improve the modelling predictions compared with experimental results. It is also proved that the size of the material has a significant influence on the hybrid properties, and the dispersion of the fibres in the hybrid material has a large importance on the failure and damage development. It can be said that this thesis gives a step forward towards the inclusion of hybrid composites into commercial design and the generation of more optimised materials.

The thesis’ advisor is Dr. Joan Andreu Mayugo (UdG). The grading panel consisted of Dr. Yentl Swolfs (KU Leuven-Belgium), Dra. Soraia Pimenta (Imperial College-UK) and Dr. Dani Trias (UdG).

Our best wishes to the brand-new doctor.
