Education

The technical platform, located in Brittany, on the Atlantic coast, has been actively involved for over 10 years in the formulation and development of polymer and composite materials. The platform operates a unique COPV testing infrastructure in Europe, dedicated to pressure cycling and burst testing of carbon fibre reinforced pressure vessels. The test facility is multi-instrumented, enabling in-depth analysis of mechanical behaviour and damage mechanisms throughout the vessel lifecycle. Instrumentation includes airborne acoustic emissions, piezoelectric acoustic emissions, strain gauges, digital image correlation (DIC), and soon high-resolution monitoring cameras, providing complementary, multi-scale experimental data during testing. Benefiting from its location within a well-established industrial and academic ecosystem, the platform has direct access to liner and pressure vessel manufacturing capabilities, supported by a very short and agile supply chain. This environment enables rapid iteration between design, manufacturing, and testing, significantly reducing development cycles. In addition to the experimental capabilities, the platform is equipped with advanced numerical simulation tools for pressure vessel analysis. Finite element modelling is used to design COPVs and to simulate their mechanical behaviour under operational and extreme loading conditions. These simulations support design optimisation and safety assessment, and are systematically validated through experimental testing, allowing verification of modelling assumptions, material laws, and failure criteria. Overall, the platform offers an integrated service, covering tank design, numerical modelling, manufacturing, and experimental validation, including personalized fatigue cycling and burst pressure tests. It is open to industrial and academic collaborations within the framework of the Horizon Europe Clean Hydrogen call and aims to support Project Leaders and Work Package Leaders in the development of safe, affordable, and sustainable GH₂ storage solutions.

By focusing on the transition from design to physical reality, the facility offers advanced pressure testing (standard cycling, custom stress profiles, and burst tests) augmented by a unique suite of monitoring tools to de-risk innovative designs: • Piezo-electric Acoustic Emissions (AE): early-stage damage detection mechanisms (fibre breakage, fibre pull-out, and matrix cracking...) • Airborne Acoustic Emissions (AAE): Non-contact measurement for precise detection of damage locations on tank surface • 3D Digital Image Correlation (DIC): Non-contact measurement technique providing surface displacement and strain data on composite materials, detection of defects, analysis of the structure’s mechanical behaviour. • Strain Gauges: Local measurements for correlating experimentally measured strain distributions with numerical model predictions. The approach minimizes the gap between virtual engineering and experimental validation by leveraging advanced Finite Element Analysis (FEA) and filament winding simulations to optimize composite architectures prior to manufacturing: • Hypothesis Validation: Systematic comparison of simulated stress fields with experimental data (DIC/AE) to refine composite damage models. • Design Optimization: Fine-tuning winding angles and liner–boss interfaces to maximize gravimetric capacity while ensuring structural integrity.   The platform acts as a catalyst for the regional hydrogen ecosystem, enabling the production of prototypes and small series through a short, localized industrial network. • Short Supply Chain (< 60 km): Strategic partnerships with local high-tech manufacturers ensure rapid iterations and a reduced carbonfootprint for prototype development. • Collaborative R&D: Seamless transition from lab-scale simulation to industrial-grade prototyping, tailored for innovative hydrogen mobility and stationary storage projects.
