An assembly for a fluid tank includes a baffle and a fluid transfer line. The baffle includes a first deflecting surface defining a first part of the tank and a second deflecting surface defining a second part of the tank. The fluid transfer line extends from the first part to the second part and is linked to the baffle by a linkage supported by the assembly. The extension of the fluid transfer line in the first part defines a first portion of the fluid transfer line, and the extension of the fluid transfer line in the second part defines a second portion of the fluid transfer line. The linkage allows for simultaneous rotation of the first portion and the second portion of the fluid transfer line towards a surface including one of the deflecting surfaces.

A method for blow molding a plastic tank from thermoplastic material, wherein the plastic tank is provided with at least one connection element penetrating the wall of the plastic tank while the plastic tank is being shaped within a blow molding tool. The connection element is fitted onto a blowing needle of the blow molding tool and is positioned in the wall by punching in the blowing needle. Also disclosed is a blow molding tool for use in the method having a blowing needle formed to fit a connection element.

A hollow molded article having a joining site where two or more split objects are welded by plastic welding and comes into contact with pressurized hydrogen, wherein an average spherulite size in a portion which is 500 μm deep inside from a surface of the hollow molded article is 20 μm or less, and a tensile strength of a test piece containing the joining site of the hollow molded article is 80% or more based on a tensile strength of a test piece not containing the joining site of the hollow molded article.

A composite fuel tank includes a tank-shell and a tank-liner, located within the tank-shell. The tank-shell is formed from a composite layup that is placed, consolidated, and cured on a bladder. The bladder forms the tank-liner after formation of the tank-shell.

A high-pressure tank includes a liner for storing a fluid, and a reinforcing layer covering an outer surface of the liner and including a fiber wound around the liner and a resin. The reinforcing layer includes a helical layer group including laminated helical layers, and a large-angle layer provided adjacent to the helical layer group and on the liner-side. The helical layer group includes an innermost layer that is closest to the liner and that is one of first and second helical layers respectively having the largest and second largest fiber winding angles, an outermost layer that is closest to an outer surface of the high-pressure tank and that is the other one of the first and second helical layers, and an intermediate layer disposed between the innermost and outermost layers and including a helical layer that is smaller in winding angle than the innermost and outermost layers.

Disclosed herein, amongst other things, is a molded article, such as a preform that is blow moldable to form a container, and a related method of forming and recycling a container. The structure and steps includes injection molding a molded article having tubular body.

A plastics container of modular construction includes a first plastics segment and a second plastics segment. The first and second plastics segments are connected to one another by plastics welding. At least one of the first and second plastics segments has a paintable surface layer on an outer side thereof or is comprised of a paintable material.

To provide a resin composition, a pellet, a composite molded article, a method for manufacturing a composite molded article and a tank, all capable of enabling tight joining and integration of the polyacetal resin molded article and the polyethylene resin molded article, and of suppressing formaldehyde emission and occurrence of mold deposit. The resin composition contains a resin ingredient and melamine, the resin ingredient containing a polyacetal resin and a maleic anhydride-modified polyethylene resin, the polyacetal resin and the maleic anhydride-modified polyethylene resin following a mass proportion of (20 to 49):(80 to 51), and molar concentration of the maleic anhydride group capable of reacting with amino group of melamine contained in the resin composition being 5 to 25 μmol/g.

A high-pressure tank producing apparatus capable of reducing time for increasing temperature of a tank body. The apparatus that heats the tank body with fibers impregnated with a thermosetting resin wound around its surface includes a heating chamber for housing the tank body and a retaining mechanism for retaining the tank body within the heating chamber, in which the heating chamber has an injection port for injecting heated gas onto the surface of the tank body and an exhaust port for discharging the gas to the outside of the heating chamber, the exhaust port being disposed in a position where the injection port is projected in a gas injecting direction, and the retaining mechanism retains the tank body in a region where the injection and exhaust ports overlap with each other as viewed from the gas injecting direction and in a position between the injection and exhaust ports.

A fiber composite structure includes a base structure being formed of a first fiber composite material that includes first fiber bundles embedded in a first matrix material, wherein the base structure includes an opening defined by first fiber bundles which include first sections and a second section that continuously or uninterruptedly interconnects the first sections, wherein the second section forms a bay that defines a part of the circumference of the opening. The fiber composite structure further includes a functional structure positioned in the opening of the base structure and joined with the first fiber composite material of the base structure.
