Thermomechanical characterization of a composite with geopolymer matrix and inorganic long fibres, and analysis of its damage. The study of the mechanical behaviour will carry on quasi-static and fatigue loadings at room and intermediate temperatures.
Development and performance of tensile and bending tests at room and intermediate temperatures.
Instrumentation of these test with acoustic emission and image correlation.
Characterization of damage by SEM and X tomography.
Modelling by finite element of damage at the mesoscale in relationships with microstructural observations and with the macoscopic thermomechanical behaviour.
Experimental mechanical characterization of composites.
Observation and analysis of microstructures
Digital Image Correlation
Contexte de travail
This post-doctoal position of 18 months will be done within the frame of a collaborative project between MATEIS (UMR 5510) and ICA Mines Albi (UMR 5312). This projects aims to study and optimize a multilayer composite with inorganic fibres and geopolymer matrix in relationships with its processing route.
This post-doc will focus on the study of the thermomechanical behaviour of this type of ceramic matrix composite in order to determine the mechanical properties, identify the damage mechanisms and evaluate the potential of this type of composite. The experimental behaviour will be studied under quasi-static and fatigue loadings from room temperature up to intermediate temperatures of several hundreds of Celsius degrees.
The experimental study will use damage characterization techniques like acoustic emission and digital image correlation, but also will need microstructural observations by SEM and X tomography. This will help to better know the damage kinetics involved at the interlayers level and give some possibilities to repare and/or reuse this type of composite.
This post-doc will occur in relationships with a second post-doctoral researcher who is already participating to this project but more precisely on the fabrication methods of the composite.
Contraintes et risques
This post-doc will be located at Villeurbanne (INSA Lyon) in the MATEIS laboratory, and some exchanges will be done with ICA at IMT Mines Albi.
