A vehicle constituent member and a manufacturing method for manufacturing the vehicle constituent member are provided. The vehicle constituent member includes: a body portion made of metal and having a vertical wall; a reinforcing member made of fiber reinforced resin and having a sheet shape, the reinforcing member being disposed on a surface of the vertical wall; and an adhesive layer provided between the surface of the vertical wall and the reinforcing member and connecting the vertical wall and the reinforcing member, the adhesive layer being configured such that a thickness of a part of the adhesive layer becomes thinner as the part of the adhesive layer is distanced outwardly from a surface end of the reinforcing member, the part of the adhesive layer being disposed outwardly from the surface end of the reinforcing member.

Disclosed are various embodiments of a structural reinforcement system. The system reinforces hollow cavities within various products to increase the structural rigidity of the product. The system generally includes a rigid carrier, a bonding material, and an insert. The rigid carrier provides the primary structural reinforcement within the cavity, and also serves as a substrate to carry the bonding material. The insert is provided to increase the structural rigidity of the reinforcement system.

A multi-material assembly is provided, as well as methods of making a multi-material assembly. The multi-material assembly includes a first coated structural component and a second structural component. The first coated structural component includes a first uncoated portion, and an adhesive is positioned between the second structural component and the first uncoated portion that secures the first coated structural component to the second structural component.

A vehicle pillar structure that includes: a first framework section that extends along a first vehicle width direction side edge of a front windshield of a vehicle; a second framework section that is provided so as to form a gap toward a vehicle rear and vehicle width direction outer side of the first framework section, that extends along the first framework section; and a see-through section that is formed so as to be see-through and that spans between the first framework section and the second framework section, wherein the first framework section and the second framework section are each formed with a closed cross-section as viewed along their length directions, and at least one of a rear edge corner of the first framework section or a front edge corner of the second framework section is formed with a beveled profile.

Structure including joint structure of dissimilar materials comprises a roof panel and a skeletal body. The roof panel has a bent portion at its end and is a panel member made of an aluminum alloy. The skeletal body has a support portion for supporting the first member and is made of steel. The roof panel and the skeletal body are joined by continuous welding of a vicinity of an apex of the bent portion of the roof panel and the support portion of the skeletal body, a reinforcing plate is joined to the roof panel at least partially along the joining portion with the skeletal body.

A side reinforced vehicle body includes a side sill inner formed in a longitudinal direction of a cabin portion, a side sill outer surrounding the side sill inner, and a side reinforcement including a zig-zag pattern cross-section and disposed between the side sill inner and the side sill outer.

Provided is a vehicle undercover having well-balanced rigidity. A vehicle undercover 10 is provided with: a plate-shaped body 12 made of a porous material such as a fiber body or a foam; and a support body 14 supporting the plate-shaped body 12. The support body 14 has a groove-shaped first frame part 20 having a horizontal plate 20a and vertical plates 20b and 20b extending from both edges of the horizontal plate 20a. Further, the support body 14 has a second frame part 22 provided across the first frame part 20 and having a smaller dimension of protrusion toward the inside of a vehicle than the first frame part 20.

A vehicle body structure includes a lower cabin made of a Carbon Fiber Reinforced Plastic (CFRP) material, an upper body made of a steel material and connected to the lower cabin, and a rear body made of an aluminum material and connected to rear sides of the lower cabin and the upper body.

A vehicle constituent member and a manufacturing method for manufacturing the vehicle constituent member are provided. The vehicle constituent member includes: a body portion made of metal and having a vertical wall; a reinforcing member made of fiber reinforced resin and having a sheet shape, the reinforcing member being disposed on a surface of the vertical wall; and an adhesive layer provided between the surface of the vertical wall and the reinforcing member and connecting the vertical wall and the reinforcing member, the adhesive layer being configured such that a thickness of a part of the adhesive layer becomes thinner as the part of the adhesive layer is distanced outwardly from a surface end of the reinforcing member, the part of the adhesive layer being disposed outwardly from the surface end of the reinforcing member.

This bonded structure includes a first member having a metal portion and a film portion disposed on at least a part of a surface of the metal portion; a second member; an adhesive layer for joining the first member and the second member to each other via the film portion. The film portion contains a resin and inorganic particles. The inorganic particles are formed of ferrosilicon or non-oxide ceramics containing V. Some of the inorganic particles protrude toward the adhesive layer. The particle size of at least some of the inorganic particles protruding toward the adhesive layer is less than the film thickness of the film portion.
