Stage - R&D - Piezoelectric Transducers Embedment in Hydrogen Composite Pressure Vessels for Structural Health Monitoring (F/M) Air Liquide – Join us to apply for this stage role. Air Liquide is a world leader in gases, technologies and services for industry and health. With a presence in 60 countries and 66 300 employees, the Group serves more than 4 million customers and patients. The company places diversity at the heart of its activities, promoting professional equality and the employment of workers with disabilities. The Paris Innovation Campus (78 – Les Loges en Josas) is Air Liquide’s largest R&D centre, hosting over 250 researchers in 48 laboratories equipped with state‑of‑the‑art experimental platforms. Hydrogen can tackle the carbon emissions of industry and intensive transport when produced from renewable resources. Air Liquide innovates in hydrogen transportation by using new‑generation tanks made of composite materials. Inspection and maintenance of such tanks are a key point for supply‑chain safety; new monitoring methods may increase efficiency in ensuring the structural health of hydrogen tanks. In this internship, you will contribute to the integration of piezoelectric transducers into hydrogen storage structures. Embedded transducers form the foundation of mec‑plasmatic approaches, enabling in‑situ monitoring of manufacturing quality and mechanical reliability throughout the tanks’ service life. Your research will establish a structured methodology for selecting and optimizing the process‑material‑transducer triad, investigating the influence of processing parameters on the mechanical properties of transducer‑instrumented composites across multiple scales under extreme loading conditions. Particular attention will be paid to interlaminar damage mechanisms, studied through the Laser Shock technique, and to the behaviour of hydrogen‑tank composite materials under quasi‑static, high‑rate dynamic, and fatigue loading. Both experimental and numerical approaches will be employed to deepen understanding of performance in critical areas, especially interlaminar failure. The outcomes will form a solid foundation for next‑generation design tools for composite hydrogen tanks subjected to complex loadings. Are you a MATCH? Master II in mechanics, instrumentation, or applied physics. Strong scientific background for understanding physical phenomena. Proficiency in experimentation and handling of sensors, actuators, connectivity, data acquisition, and signal processing. Motivation to carry out various material characterisation tests. Solid knowledge in mechanics is appreciated. Experience in material characterisation. Additional Information Air Liquide has been awarded the Happy Trainees label. The internship will take place at Campus Innovation Paris, Air Liquide’s R&D centre in Loges‑en‑Josas (1, Chemin de la Porte des Loges) and at the PIMM Laboratory (ENSAM Paris). Desired start date: end of 2025. Duration of the internship: 6 months. Seniority level Internship Employment type Full‑time Job function Research, Analyst, and Information Technology Industries Chemical Manufacturing Our differences make our performance. At Air Liquide, we are committed to building a diverse and inclusive workplace that embraces the diversity of our employees, customers, patients, community stakeholders and cultures across the world. We welcome and consider applications from all qualified applicants, regardless of their background.
