Provided is a method of molding, by using a mold, a component including a metal plate and a thermoplastic resin containing a thermoplastic resin arranged on a surface on one side of the metal plate, the mold including at least a movable mold and a fixed mold including a support portion. Specifically, the molding method includes: an arranging step of arranging a premolded metal plate within the mold; a fixing step of fixing the metal plate by pressing the metal plate against the movable mold with use of the support portion; and a molding step including forming a cavity between the fixed mold and the metal plate by closing the mold, bringing the thermoplastic resin into close contact with the metal plate, and forming an exposed portion by exposing the metal plate out of the softened thermoplastic resin with use of the support portion. With this, without leakage of the thermoplastic resin, a joint region to a metal surface of another component can be reliably secured.

Method of forming component using metal-resin composite and mold for forming said component

A composite structural body (A) includes a first metal member (M) having a plate-like shape, a second metal member (M) having a plate-like shape, and a resin member (R) that integrates the first metal member (M) and the second metal member (M) with each other. The resin member (R) includes a first resin layer (R) that coats astride one main surface of the first metal member (M) and one main surface of the second metal member (M), and a second resin layer (R) that coats astride another main surface of the first metal member (M) and another main surface of the second metal member (M). The composite structural body (A) is provided as a composite structural body that has satisfactory moldability, that is capable of securing sufficient strength, and that is suitable as a component of a structure such as a vehicle body.

Composite structure and manufacturing method therefor

A vehicle body structure includes a body side section () configured of a first composite component () and a body lower section () configured of a second composite component (). Each of the first and second composite components () comprises a metal plate () and a fiber reinforced thermoplastic portion () that contains discontinuous fibers. The fiber reinforced thermoplastic portion () of the first composite component () includes a lining layer formed on the metal plate () and reinforcing ribs raised from the lining layer. The fiber reinforced thermoplastic portion () of the second composite component () includes a planar portion () infilled in an opening () opened on the metal plateThe discontinuous fibers in the fiber reinforced thermoplastic portion () of the second composite component () are longer than the discontinuous fibers in the fiber reinforced thermoplastic portion () of the first composite component ().
