After winning the SAMPE France & Europe, Saber will participate in the CAMX – the Composite & Advanced Materials eXpo in October 2018, in Dallas. This event is organized by ACMA and SAMPE.
Student group at the SAMPE Europe Symposium 2017
SAMPE France : Technical Days
Sponsored by the IRT Saint Exupéry, the cocktail reception of the SAMPE France days, in collaboration with Airbus (sponsor of the gala diner), took place on November 23rd. This event was the occasion for Saber to present his work in front of an audience of 400 industrials.
Ariel Sirat, IRT’s CEO, also presented the Thermoplastics and Addictive Manufacturing activities of IRT Saint Exupéry in a speech.
About this thesis
In the frame of COMPINNOVTP project, new high performance thermoplastic solutions are investigated to contribute to further mass and cost reduction for the aerospace industry. But current composites have too low electric conductivity properties because of the polymer matrix. In order to insure without risks the electrostatic charge flow (as lightning strike, air friction…) IRT Saint Exupéry investigates conductive fillers integration in a high performance polymer.
One of the studied polymer has lower fabrication costs and lower processing temperatures compared to others. It also may have different formulations with different properties. The possibility of varying the physicochemical properties of polymer is very interesting, but the difficulties related to the control of crystallization make it a disadvantage. Saber Chelaghma researches aim to understand these phenomena to improve control and optimization of manufacturing cycles of carbon fibers reinforced polymer.
The final objective is the identification of the process parameters to obtain optimum mechanical properties during manufacturing cycles.
