A high-pressure tank comprising: a resin liner for a high-pressure tank including at least one opening portion; an aluminum mouth portion attached to the opening portion; and a reinforcement layer formed on an outer surface of the liner, wherein an aluminum oxide coating is formed on a surface of the aluminum mouth portion, the aluminum oxide coating includes a porous surface layer in which columns with an average height of 10 to 100 nm are arranged in a dispersed state, an average value of a percentages of the protruding portion area of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 5.0 to 26.0%, and an average value of the numbers of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 500 to 2000.

High-pressure tank

An object is to provide a metal-resin bonded member that is easy to manufacture and has high bonding strength. The metal-resin bonded member includes a metal body having an iron oxide layer on the surface and a resin body bonded to the metal body via the iron oxide layer. The iron oxide layer has a thickness of 50 nm to 10 &#x3bc;m. The iron oxide layer comprises 60-40 at % Fe and 40-60 at % O at the outermost surface side. The iron oxide layer contains magnetite (FeO). The iron oxide layer is formed by heating the surface of an iron-based substrate at 200-850&#xb0; C. in an oxidation atmosphere. The resin body is composed of polyphenylene sulfide (PPS). The bonding of the metal body and the resin body via the iron oxide layer can be carried out by insert molding, thermal adhesion utilizing friction heating, etc.

Metal-resin bonded member and method of manufacturing the same

Provided is a joined body comprising a first joined member, a second joined member, and a joining layer that joins the first joined member and the second joined member, wherein the first joined member and the second joined member are each independently one selected from the group consisting of a metal member, a polyamide resin member, and a polyolefin resin member, and the joining layer is a layer formed of a resin composition having a co-continuous phase including a continuous phase A farmed of the polyamide resin and a continuous phase B formed of the polyolefin resin and has a dispersed domain a distributed in the continuous phase A, a finely dispersed subdomain a' distributed in the dispersed domain a, a dispersed domain b distributed in the continuous phase B, and a finely dispersed subdomain b&#x2032; distributed in the dispersed domain b.

Joined body

A metal-resin composite material including an aluminum substrate having an aluminum oxide coating and a resin bonded to the aluminum substrate through the aluminum oxide coating, wherein the aluminum oxide coating has a porous surface layer in which columns with an average height of 10 to 100 nm are arranged in a dispersed state, an average value of sums of cross-sectional areas of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 8000 to 128000 nm, an average value of sums of circumferential lengths of cross-sections of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 1000 to 27000 nm, and an average value of numbers of the columns in randomly sampled 400 nm square visual fields of the porous surface layer is 10 to 430.

Metal-resin composite material, method for producing the same, and aluminum substrate having aluminum oxide coating

A molecular assembly comprising a host metal complex with a space formed therein, and compounds having substituents enclosed in the metal complex within the space and molecular chains bonded to the substituents and extending to the exterior of the metal complex, wherein two or more substituents are enclosed in the same space of the metal complex.
