In an automotive structural member, weight efficiency of impact resistance is improved. An automotive structural member includes: a hollow member having plane portions; and an FRP member joined to at least one section of the plane portions, wherein: the FRP member is joined to a region of at least 0.1L1 to 0.9L1 of a length L1 in a longitudinal direction of the hollow member; the plane portion is formed with an FRP joint portion being a portion to which the FRP member is joined and an FRP non-joint portion being a portion to which the FRP member is not joined, in the region of 0.1L1 to 0.9L1; a total width of the FRP joint portion is 8 to 60% of a full width of the plane portion, in the plane portion; and a flexural rigidity of the FRP member in the FRP joint portion is 30 times or more a flexural rigidity of the plane portion excluding the FRP member in the plane portion.

The present invention relates to a chassis (10) for a vehicle comprising a plurality of sandwich plate elements (100) and a plurality of connection elements (200, 200′, 200a-c) for connecting said plurality of sandwich plate elements (100). Each connection element (200, 200′, 200a-c) comprises two or more recesses (210, 220) configured to receive an edge portion (160) of one of the plurality of sandwich plate elements (100). The plurality of connection elements (200, 200′, 200a-c) comprises at least one connection element (200′, 200a-c) which has at least one external surface (202a-e) provided with a connection configuration (250a-e) for a mortise and tenon type joint. A method (20) for forming a chassis (10) for a vehicle is also provided.

An embodiment floor structure of a vehicle includes a pair of side seals disposed to face each other in a vehicle width direction, and respectively disposed in a vehicle length direction, a floor frame disposed between the pair of side seals and including a pair of longitudinal frames respectively arranged along the pair of side seals and at least one transverse frame mounted between the pair of longitudinal frames in the vehicle width direction, and at least one core structural member disposed in a space provided by the floor frame and including a material for absorbing impact.

A vehicle body includes a structural member having an inner surface defining an elongated cavity. The structural member includes an outer panel member joined to an inner panel member. A tension web secured in the cavity separates the outer and inner panel members. A reinforcement member is positioned in the cavity of the structural member. The reinforcement member contacts the transverse web and a gap is provided between the reinforcement member and the inner surface of the structural member. The reinforcement member including a base member having a plurality of bumpers extended in a width direction of the reinforcement member. The plurality of bumpers face one of the inner surface and the tension web. An adhesive secured to the reinforcement member is activatable to expand toward the inner surface to define a joint between the reinforcement member and the structural member and to at least partially fill the gap.

A gutter member has a flow path portion that receives the water dripping from a front windshield and flows the received water in the vehicle width direction and a drain portion that drains the water to a drain member on the inner side in the vehicle width direction of the flow path portion, in which at least a part of the flow path portion overlaps with the drain path in vehicle plan view, the gutter member has guide portions that guide the water dripping from the drain portion to the drain path, and the guide portions, include a cushioning material that absorbs an impact load at least in the vertical direction.

An embodiment vehicle body includes a tubular part extended in a longitudinal direction of a vehicle and having a hollow shape, a base part in which the tubular part is inserted, the base part integrally connecting an A pillar to a side portion of a roof, and an outer garnish shaped to be extended in the longitudinal direction along the base part and coupled to the base part to cover the base part.

A vehicle roof stiffener includes at least one fiber reinforced polymer (FRP) portion and at least one metal or metal alloy portion. The FRP portion includes at least one transition structure including a metal or a metal alloy. At least some of the fibers of the FRP portion are embedded in the transition structure. The metal or metal alloy portion is secured to the transition structure of the FRP portion. In an example vehicle roof stiffener, the metal portion extends parallel to a longitudinal axis of a vehicle, and the FRP portion extends transverse to the longitudinal axis. The example vehicle roof stiffener may include a front FRP portion, a rear FRP portion, and two metal side portions. The metal side portions and the FRP portions may be joined by welding the transition structures to the metal portions.
