Development and health monitoring of damage tolerant aerospace composites using advanced inter laminar nanofiber. These nanofibers are made of nylon 6,6 electrospun on prepreg material. The project consist in creating these new composite materials, and then specify and run tests to assess their structural properties. Interlaminar fracture toughness (DCB.

• PROJECT "From Plants to Planes": improving performance of composite aerospace structures using Cellulose Nano-Crystals (CNCs) derived from vegetable materials.AIM: produce a new generation of composites with.
• Gather a literature review on the different existing technics to toughen composites, as well as their utilisation in aerospace structure and the way to make them benefit efficiently from CNCs.
• Plan and execute series of experiments to incorporate the CNCs in the composites and evaluate the impact of their concentration on the interlaminar fracture toughness.
• Model the fracture initiation and the crack propagation found in the sample on an aerospace component (stiffener).
• Present the work done and results obtained: at 0.67 g/m² the increase was of 186% in mode I interlaminar fracture toughness initiation. These were beyond expectations and called for further research.

• Study and comparison of different mechanical properties of epoxy sealants during curing.GOALS:
• Establish a correlation between the evolution of different mechanical properties: hardness, shearing strength, compression strength, and stiffness in function of temperature for different mastics types
• Examine the suitability of the hardness test as an indicator of the mastic polymerization state
• Gather a database of tests results to optimize the manufacturing steps duration during a tanker membrane’s fabrication.SKILLS:
• Communication with engineers and technicians in the team
• Autonomy in mechanical tests specification, planning and execution

The "Entrepreneurial" is a competition where groups of engineers and accountants students simulates the creation of a start-up around a project that is innovative. The simulation includes technical product specifications and creation of credible business plan. Technical leader of a 4 student team, we designed the HDream project which won the "Manag'Ing.

• Within the R&D department on site, I was charged to prepare the samples (catalysts in the form of granules) before expedition to the customers, including:
• Collecting appropriate production samples in the industrial site
• Processing various machines so the samples are fit for shipment
• Communicating with the laboratory to check the samples meet the quality requirement
