This invention provides a seamless nanocomposite vessel, which includes a high density polymer adapted into the shape of a desired vessel, the vessel having an inner surface sputtered with a metal and an outer surface, the inner surface defining a space; and a plurality of layers disposed over the inner surface of the vessel, the outer surface of the vessel, or both, each layer being independently selected from the group consisting of a thermoplastic material and a thermoset nanocomposite material. Methods for making and using such vessels also are provided.
摘要:
Un procédé de fabrication d'un corps creux comprenant au moins un composant comprenant un canal consiste à mettre en oeuvre les étapes suivantes : • - mise en forme d'une feuille (3) de matière plastique par application dans un état fondu contre l'empreinte (12) d'un moule, • - alors que la feuille (3) est encore dans un état fondu, formation du composant par injection de matière plastique dans une cavité (5, 5') d'injection débouchant sur la feuille (3), de sorte que la matière plastique injectée entre en liaison avec la feuille (3), ladite cavité d'injection (5, 5') ayant la forme d'au moins une partie du composant, • formation d'un orifice de communication traversant la feuille de manière à créer une communication entre l'intérieur et l'extérieur du corps creux via le canal du composant obtenu. L'invention concerne aussi un moule et un procédé complet de fabrication d'un réservoir à carburant.
摘要:
The invention relates to a container (1) of thermoplastic material with at least one support (4), which is arranged in the interior of the container, extends between opposing container walls (2) and is anchored at each end to the container walls with a positive engagement and/or a material bond, the support (4) comprising at least one supporting strut (5) and the supporting strut (5) substantially absorbing a supporting load on the container walls (2) induced by negative pressure in the container, and a tensile force that is induced by positive pressure being absorbed by at least one tension-resistant bracing element in the form of a tension-resistant band (8) which extends between the container walls (2).
摘要:
The present invention relates to a process for manufacturing a hollow body comprising a thermoplastic wall and a fibrous reinforcement welded on at least one portion of the surface of said wall, preferably its outer surface, the fibrous reinforcement comprising a thermoplastic similar to or compatible with that of the wall of the hollow body, having a thickness of at least 1 mm and comprising from 30 to 60% in weight of fibres, according to which: - the portion of the outer surface of the hollow body where the reinforcement will be welded is heated; - the fibrous reinforcement is also heated so as to soften or even preferably melt the thermoplastic of the reinforcement; and - the reinforcement is moved to and applied to said portion of the outer surface of the hollow body, wherein the step of applying the reinforcement to said portion of the outer surface of the hollow body comprises: - applying an initial pressure on at least one portion of the reinforcement; - applying pressure for the final welding using robotized pressure applying means.
摘要:
The invention relates to a fuel tank of thermoplastic polymer for a motor vehicle, having at least one reinforcing element inside the fuel tank, the reinforcing element inside the fuel tank extending between opposing tank walls (15), parts of the reinforcing element passing through the tank wall and parts of the reinforcing element engaging behind the tank wall from outside, the fuel tank being distinguished according to the invention in that the reinforcing element (8) is provided with at least one multipart fastening head (11), which comprises a first closing means engaging through the tank wall (15) from inside and a second closing means engaging through the tank wall (15) from outside, which closing means are of mutually complementary construction.
摘要:
A fuel tank baffle assembly is provided for installation in a fuel tank, the baffle assembly comprising a main body having a first end section, a second end section, and an intermediate section interconnecting the first and second end sections. Operably associated with the main body is at least one deployable auxiliary baffle structure. The auxiliary baffle structure is configured to be positioned in an undeployed state during installation into a fuel tank, thereby defining a first installation width of the baffle assembly. Following installation, the auxiliary baffle structure is deployed into an extended position, thereby defining an operational width for subsequent usage. The operational width is greater than the installation width.
