Abstract[English]
A storage vessel can include a shell that is formed by fibers wound about an axis and infused with a resin matrix. The resin matrix can include metal nanoparticles coated with a polymer and distributed within a resin. The nanoparticles provide low coefficients of thermal expansion, and the polymer coatings enhance their bonding with the resin The shells of such storage vessels provide increased tensile strength and modulus at both room and cryogenic temperatures. Such improvements stem from the higher interfacial residual thermal stress at cryogenic temperature due to their low thermal expansion properties, which in turn promotes crack branching that increases the energy dissipation of the matrix.[French]
L'invention concerne un récipient de stockage pouvant comprendre une coque qui est formée par des fibres enroulées autour d'un axe et infusée à l'aide d'une matrice de résine. La matrice de résine peut comprendre des nanoparticules métalliques revêtues d'un polymère et distribuées à l'intérieur d'une résine. Les nanoparticules fournissent de faibles coefficients d'expansion thermique, et les revêtements polymères améliorent leur liaison avec la résine, les coques de tels récipients de stockage fournissant une résistance à la traction et un module accrus à la fois à la température ambiante et à des températures cryogéniques. De telles améliorations se produisent à partir de la contrainte thermique résiduelle interfaciale supérieure à température cryogénique due à leurs propriétés de faible dilatation thermique, ce qui à son tour favorise la ramification de fissures qui augmente la dissipation d'énergie de la matrice.
