“…Therefore, the possible collapse phenomenon is mainly affected by the dissolved gas into the interface layer between the liner and composite. [68] They revealed that liner collapse damage behavior after the depressurization of exposed high-pressure hydrogen can be explained similarly to RGD in rubber materials. During the compression phase and saturation time, the gas is dissolved into the material following Henry's law until an equilibrium is reached where there is no pressure gradient between the free surface of the specimen and the interface between liner/composite.…”

“…[10] The additional test results on identifying key parameters on liner collapse and major mechanisms on collapse initiation were used for the modeling of collapsing damage behavior. [68] The numerical modeling revealed that the swelling of the material as a result of gas compression or decompression has no significant effect on liner collapse. Therefore, the possible collapse phenomenon is mainly affected by the dissolved gas into the interface layer between the liner and composite.…”

“…The results showed that the decompression seemingly increased the size of the preexisting cavities as well as those created during tension. [105] The liner collapse behavior during the high-pressure hydrogen loading and unloading conditions was tested at a laboratory-scale by P epin et al [10,68] As the actual pressure vessel liner collapse is an expensive test, they developed a laboratory-scale liner collapse test method. A thermoplastic polymer (PA 6, T g $42 C) plate was used as the liner material and the testing specimens were prepared as liner/composite/liner layered specimens for tests at 30 MPa at 50 C in an autoclave with high-pressure hydrogen.…”

“…[67] Furthermore, accumulated stresses on the liner/shell interface due to dissolved gas during exposure periods even lead to the collapse of the liner during depressurization phases. [10,27,68,69] Moreover, the atmospheres, which are apparent in real operating conditions, for example, a range of temperatures, the cyclic and complex loading (tensile, compressive, and shear), long working periods, surrounding media, etc., strongly affect the expected performance of the polymeric components. [70,71] Therefore, the degradation, which reduces the expected functionality, and life-time of polymeric components used in high-pressure hydrogen conditions, is governed not only by the material properties but also the extreme environmental conditions.…”

Typically, polymeric materials experience material degradation and damage over time in harsh environments. Improved understanding of the physical and chemical processes associated with possible damage modes intended in high-pressure hydrogen gas exposed atmospheres will help to select and develop materials well suited for applications fulfilling future energy demands in hydrogen as an energy carrier. In high-pressure hydrogen gas exposure conditions, damage from rapid gas decompression (RGD) and from aging in elastomeric as well as thermoplastic material components is unavoidable. This review discusses the applications of polymeric materials in a multi-material approach in the realization of the "Hydrogen economy". It covers the limitations of existing polymeric components, the current knowledge on polymeric material testing and characterization, and the latest developments. Some improvements are suggested in terms of material development and testing procedures to fill in the gaps in existing knowledge in the literature.

“…De nombreux travaux ont déjà été menés sur ces réservoirs, tant d'un point de vue expérimental que numérique. La prédiction de la pression maximale avant éclatement [2], l'effet des cycles thermiques [3][4][5][6], la tolérance aux défauts et aux dommages [7][8][9], la tenue au feu [10], le collapse du liner [11][12] sont des thématiques étudiés généralement à l'échelle des échantillons et numériquement. Mais de plus en plus, des essais sur réservoirs sont menés afin de comprendre, par exemple, les mécanismes de tolérance aux dommages par la technique d'émission acoustique [13][14].…”

De nombreux travaux ont déjà été menés sur les réservoirs haute pression de type IV, tant d'un point de vue expérimental que numérique. La prédiction de la pression maximale avant éclatement, l'effet des cycles thermiques, la tolérance aux défauts et aux dommages, la tenue au feu, le collapse du liner sont des thématiques étudiées généralement numériquement à l'échelle des échantillons. Dans ces travaux le passage de l'éprouvette à la structure n'est pas complétement validée par une confrontation des modèles avec des mesures expérimentales à l'échelle du réservoir. Toutefois une corrélation avec la simulation numérique, nécessite de récolter un grand nombre d'informations souvent en associant plusieurs métrologies. Dans ce travail des essais instrumentés non-destructifs sur un réservoir soumis à une pression interne ont été réalisés couplés avec des mesures optiques (champs de déplacements 3D) et des mesures par émission acoustique pour comprendre la cinétique d'endommagement. Trois essais de charge-décharge sont réalisés à des vitesses de 1, 10 et 100MPa/min jusqu'à la pression de 87.5MPa, ils sont suivis d'un essai cyclé. Les résultats obtenus sont reproductibles et ils permettent de montrer que la vitesse de mise en pression n'a pas d'influence sur la cinétique de déformation et sur l'endommagement du réservoir.

High‐density polyethylene (HDPE) is a popular material for use in medical, packaging, and construction applications due to its low cost and good processing characteristics. Its chemical stability and resistance make it particularly suitable for use in storage tanks for chemicals and gases. However, its low gas barrier properties and limited strength have hindered its widespread use in such applications. This study puts forward a novel approach, micro‐nano torsional laminated extrusion (MNTLE), for preparing HDPE/montmorillonite (MMT) nanocomposites with improved mechanical and gas barrier properties. The MNTLE method yields a more uniform of fillers in the composites, which leads to greater mechanical strength (a 46.18% increase in tensile strength and a 27.37% rise in elongation break), along with a higher crystallinity (a 16.27% increase) compared to compression molding. Moreover, the improved dispersion and orientation of the Nano‐MMT in composites fabricated by MNTLE lead to a 41.9% reduction in oxygen permeability compared to press‐molded composites. Consequently, this study introduces an innovative processing method that enhances the mechanical and gas barrier characteristics of the material, thus offering potential applications in the manufacturing of lining materials for Type IV hydrogen storage tanks.Highlights The MNTLE method is used to process composites. The MNTLE significantly improves the dispersibility of the filler. Mechanical properties of composites processed by MNTLE are enhanced. The crystallinity of the reinforced composite increased by 16.27%. The oxygen permeability of the composite prepared by MNTLE is reduced.
