A molding mold for a composite bodyfor forming a composite body A that integrally molds a resin member R on one main surface of a metal panel P, including at least a fixed moldand a movable mold, and including, in a mold on the resin member side among the fixed moldand the movable mold, a panel fixing mechanismthat fixes an edge portion of the metal panel Pin a state in which the fixed moldand the movable mold are open. The molding mold for a composite bodyeliminates a movable body with respect to a molding space of the resin member R and overcomes the generation of burr in the resin member R, and forms an exposed metal portion B on the edge portion of the metal panel Pon the resin member R side by the panel fixing mechanism

Molding mold for composite body

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 ().

Vehicle body structure

A vehicle bumper is provided integrally to include metal beam-extension portions on both right-and-left end sides of a metal bumper-beam portion. In this vehicle bumper, the bumper-beam portion and the beam-extension portion include a vertical wall portion, an upper wall portion and a lower wall portion, and a resin reinforcing rib is joined to inner surfaces of a void formed of each of the wall portions. In addition, in this vehicle bumper, an extension dimension of the upper wall portion and the lower wall portion of the beam-extension portion is larger than an extension dimension of the upper wall portion and the lower wall portion in the bumper-beam portion, the resin reinforcing rib in the beam-extension portion is joined to the vertical wall portion, the upper wall portion, and the lower wall portion of the beam-extension portion; and the stiffness of the bumper-beam portion is higher than the stiffness of the beam-extension portion.

Bumper for vehicle

Provided is a composite (A) including a metal plate (B) and a reinforcing member (C) that is made of a resin. The metal plate (B) includes a joint portion () that is continuous with one end of a body portion (), a hole that is formed through the body portion () in a thickness direction of the body portion () in the proximity of the joint portion (), and a guide portion provided around the hole. The reinforcing member (C) continuously includes a main portion (), a coupling portion () formed in the hole (), and a locking portion () that is held in close contact with a surface on another side of the body portion (). The guide portion () is at least one of a protruding portion provided on at least one of a rear side and a lateral side relative to the hole () in a direction from the body portion () to the joint portion (), and a recessed portion extended from a front side relative to the hole () to the hole () in the direction from the body portion to the joint portion. In insert molding of the composite (A), a molten resin is introduced preferentially into the hole (). With this, the joint portion () is formed reliably in good condition free from adhesion of the resin.
