About Me
Graduate of a Master of Sciences, I’m an engineer specialised in Structural Mechanics such as the ones found in aeronautics.
I've gained a overall understanding of the industry and applied research. I studied material shaping processes and stepped in mechanical design. I also developed transverse skills when I sold electrohydraulic systems for British and Irish customers during my previous position.

Research Engineer in Numerical Simulation - Moulding of a thermosetting material reinforced with mid-long discontinuous fibres
Clément Ader Institute (research lab in material shaping processes, Mines d'Albi-Carmaux Graduate School)
September 2011
to December 2012
Full-time
Albi
France
- Identified chemical, thermal and rheological constitutive models with global non-linear optimisation on Scilab.
- Simulated preheating and filling of highly-reinforced thermosetting materials with mid-long discontinuous fibres (reshaping of epoxide resin / carbon fibre prepreg remnants with metallic inserts) on Moldflow Insight.
- Simulated moulding process (curing, injection, cooling and mechanical behaviour).
- Conducted statistical analysis and extrapolated manufacturing parameters.
- Highlighted process enhancements on aeronautical parts (secondary structures).
Detailed Description
- Studied non-linear global optimisation methods.
- Formulated constitutive models.
Company Description
The project was carried out in partnership with Equip'Aero at the Clément Ader Institute based at the Mines d'Abli-Carmaux high-school. Researches in plastic and metallurgical shaping processes are conducted at their lab.
The process consisted in moulding 3D thick parts with uncured prepreg remnants (woven fibres bond with thermosetting material) and mechanical parts. The study was supervised by a PhD student in charge of the moulding of mechanical tensile specimens.
I analysed his results to model the material behaviour and simulate the whole process. The simulations helped him design cavities to mould industrial parts and conduct more advanced characterisations.
