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 μm. 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 (Fe.sub.3O.sub.4). The iron oxide layer is formed by heating the surface of an iron-based substrate at 200-850° 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.

Techniques are described for injection molding. When material inside a cavity of a tool is solidified into a molded part, the tool imparts a finished surface onto the part, including sidewalls with a zero or low-draft angle. To allow separation from the cavity without using sleeves or sliders, the cavity is widened, just prior to the part being ejected. The tool is made from metal with a high coefficient of thermal expansion, so the size of the cavity can be manipulated using temperature control. Heat applied to an outer portion of the metal surrounding the cavity pulls the metal away from the part creating an air gap within the cavity. Carefully applied cooling to an inner portion of the metal blocks the heat and keeps the surface temperature under control, which preserves the finished surface on the part. When the air gap allows, the part releases from the cavity with the finished surface intact.

A reinforcing element for a bodywork part made from plastic, forming an insert capable of being at least partially overmolded in the bodywork part, the reinforcing element including a wall delimited by a contour, the wall including an orifice that passes all the way through the thickness of the wall of the reinforcing element, which orifice is a notch emerging at the contour, or a blind orifice at the contour, located, at least in part, in an area of the contour that extends over 40 mm in width from the wall.

A vacuum insulated structure includes a trim breaker having a wrapper channel and a liner channel that extend perimetrically about the trim breaker. An inner liner is attached to the trim breaker at the liner channel. An outer wrapper is attached to the trim breaker at the wrapper channel. A metallic plate is disposed within the trim breaker and extends from a first area proximate the liner channel to a second area proximate the wrapper channel. The metallic plate defines an internal barrier to gas permeation through the trim breaker.

Provided are: a metal-resin composite structure, including a surface-roughened metal member and a resin member bonded to the metal member and composed of a polyarylene sulfide resin (PAS) composition; a PAS resin composition and a resin member, for use in the metal-resin composite structure; and a method. More specifically, provided are: a PAS resin composition including a PAS resin (A) and a phenol resin (B) in an amount of 0.05 to 20 parts by mass with respect to 100 parts by mass of the resin (A); a resin member obtained by melt-molding the PAS resin composition; and a metal-resin composite structure including a surface-roughened metal member and a resin member bonded to the metal member and composed of the PAS resin composition, wherein the metal member is made of aluminum, copper, magnesium, iron, titanium or an alloy containing at least one of them; and a method for producing the same.

In a metal-fiber reinforced plastic (FRP) composite, the FRP and the metal member are bonded together, so internal stress (thermal stress) is generated due to the misfit of coefficients of thermal expansion of the metal member and the FRP. Not only does the binder layer peel off and the mechanical properties of the FRP cannot be obtained, but also defects in appearance (surface strain) occur. Therefore, the technical problem is to secure the mechanical properties as a composite while easing the internal stress and keeping surface strain from being generated. The metal-fiber reinforced plastic (FRP) composite according to the present invention solves the technical problem by sandwiching an FRP between two metal members and not having at least one of the metal members joined (bonded) with the FRP. Further, it is possible to arrange an intermediate member between the other metal member and the FRP and sandwich the FRP between the two metal members through the intermediate member.
