Abstract: A method for manufacturing a metal-resin composite includes preparing a mold including a first mold forming a housing portion and a second mold movable with respect to the first mold, housing an extruded material in the housing portion, arranging resin material on the first mold, moving the second mold to form a cavity defined by the extruded material and the mold, and filling the cavity with the resin material. In the filling, a protrusion of the extruded material is brought into close contact with the housing portion or its peripheral edge by molding pressure applied from the mold to the extruded material, and the cavity is disconnected from a gap between an inner surface of the housing portion and the extruded material.

Abstract: A metal-resin composite includes: a metal plate including at least one cut-and-raised portion including a cutout hole and a cut-and-raised piece; and a resin material disposed only on one surface side of the metal plate, the resin material cured by burying the cut-and-raised portion, the resin material integrated with the metal plate.

Abstract: A double-lock vehicle hood that can secure flare rigidity, dent resistance, and pedestrian protection performance in a region near the center between a pair of strikers while suppressing an increase in manufacturing cost and weight. The vehicle hood includes an outer panel, an inner panel disposed below the outer panel, and a left striker and a right striker provided on the inner panel and disposed separately in a vehicle lateral direction. The inner panel includes an inner joining part projecting from a bottom toward the outer panel inside an outer joining part. The inner joining part includes a body part disposed behind the left and right strikers and joined to the outer panel, and an extension part extended forward from the body part to be disposed between the left and right strikers and joined to the outer panel.

Abstract: Provided is a vehicle hood capable of improving pedestrian protection performance by suppressing an increase in acceleration secondary peak while increasing an acceleration primary peak. A vehicle hood includes an outer panel, an inner panel, and a deformable part that deforms with the outer panel when the outer panel deforms toward the inner panel, in which the inner panel includes a bottom, an upright wall, and an opposed part, and the deformable part includes a joint part joined to an intermediate wall of the upright wall or the opposed part, and a displaceable part that is close to or in contact with the outer panel above the bottom and is capable of being downward displaced with the outer panel to below the joint part when the outer panel deforms toward the inner panel.

Abstract: Provided is a vehicle hood that allows a reduction in thickness of an outer panel while providing stiffness of the outer panel. A vehicle hood includes an outer panel, an inner panel, and a plurality of adhesive components. The inner panel has a plurality of beads. Each bead has a support part that supports each adhesive component. The adhesive components are provided on the support parts so as to be intermittently aligned along a specific direction. A support-part interval between the support parts adjacent to each other in an intersecting direction is smaller than an adhesive-component interval between the adhesive components adjacent to each other on the support parts.

Abstract: There is provided a vehicle hood capable of decreasing a HIC score at each side in a breadth direction. A vehicle hood includes an outer panel and an inner panel, in which the inner panel includes a bead bottom and a plurality of beads; the bead bottom includes an outermost bottom that is located on an outermost side in a breadth direction and has a shape extending in a longitudinal direction, and an inner bottom that is located inside the outermost bottom and has a shape extending in the longitudinal direction; the beads include a lateral bead having a shape extending in the longitudinal direction between the outermost bottom and the inner bottom; and the lateral bead includes an outermost vertical wall, an inner vertical wall, and an outermost opposing part.

Abstract: A vehicle hood structure includes a hood outer panel and a hood inner panel. The hood outer panel includes at least one character line extending substantially in a vehicle front-rear direction. The character line intersects a central line that extends in a vehicle width direction and that passes through a central point where a center of the hood outer panel in the vehicle front-rear direction and a center of the hood outer panel in the vehicle width direction are superposed on each other. The character line intersects the central line at an intersection point positioned within a region extending from the central point by 300 mm or less in the vehicle width direction.
