The objective of this internship will be to characterise the electrical conductivity of carbon fibres which will be printed in a composite, we can then talk about 3.5D or 4D printing for a probable use as actuators in mechatronics systems.
The work during this internship will be divided into several steps:
- A academics will be provided on the composite 3D printer of the SYMME laboratory
- A search for CAD models allowing the printing and characterisation of the fibres
- The design and development of a test bench to electrically characterise the fibres alone and
fibres alone and then fibres printed in a part
- Consider measuring the electrical conductivity of the fibres when the part is under mechanical
mechanical stress
- The writing of a report on the work will conclude this internship

The link with the teaching provided at the Polytech Annecy-Chambéry engineering school is
the development of new materials and their characterisation. The student
will be able to learn about the development of test benches and their implementation protocols.
This internship will allow the student to immerse himself in the world of applied laboratory research
The results of this work will be used to develop a new product or service, or to improve the quality of the product or service.
The results of this work will be used to write scientific articles that will be published
in dedicated scientific journals.

The candidate must be interested in discovering the world of university research, be curious, have a strong sense of
curious, proactive, rigorous and methodical, and attracted by experimentation. Knowledge of
knowledge of electrical engineering or electricity will be highly appreciated.
