A key design issue for new hydrogen-based vehicle drive systems is assuring safety of the start-of-the-art polymer lined, carbon fiber overwrapped vessels working at pressures over 700 bar. Cikoni will describe how a multiscale approach gives a better estimation of burst pressures and insight into damage mechanisms for different laminate layups, at both the macroscopic and micromechanical levels, to validate simulation models for structural optimization of layups, along with life predictions.
The recording is about 28 minutes long and was originally presented at the 2020 ATCx Composites.
