A panel structure includes: a panel made of metal; and a reinforcement joined to the panel and made of a plurality of FRP layers including continuous fibers, in which each of the plurality of FRP layers has a single fiber direction, at least one layer out of the plurality of FRP layers has a fiber direction different from that of another layer, in the plurality of FRP layers, a proportion of layers having an angular difference in the fiber direction of 30° or more is 15% or more of all of the layers, and when calculating, by defining a long side direction being a long direction of a long edge of the panel as a 90° direction and a direction orthogonal to the 90° direction as a 0° direction, each of a 90° direction component and a 0° direction component regarding the fiber direction of each FRP layer of the reinforcement joined to the panel, by using a trigonometric function, an expression (1) is satisfied.

A front end module frame may include a cross member, a pair of side members extending from respective end portions of the cross member in a height direction of the vehicle, each of the pair of side members having a center portion connected to the front end portion of a corresponding one of front side members of the vehicle, an upper back beam member interconnecting the upper end portions of the pair of side members, the upper back beam member having opposite end portions respectively connected to the front end portions of upper fender apron members of the vehicle, and a lower back beam member extending in a width direction of the vehicle and interconnecting the center portions of the pair of side members.

A vehicle lower structure includes an under cover. The under cover includes: a cover body located under an exhaust pipe and installed on a vehicle body; a lid detachably attached to the cover body and configured to close a work hole penetrating the cover body in an upper-lower direction when the lid is attached to the cover body and to open the work hole when the lid is detached from the cover body; and a baffle made of a metal material and installed in an area of an upper surface of the lid that includes a portion closest to the exhaust pipe and its surroundings.

A trunk lid for closing a trunk of a notchback motor vehicle includes at least one inner part having a receiving space for at least one antenna of the motor vehicle and at least one outer cladding part connected to the inner part. The outer cladding part is formed of a material that is permeable to radio waves at least in a region where radio waves are to pass through. A notchback motor vehicle includes the truck lid.

In an automobile inner panel and an automobile panel that includes the automobile inner panel, panel rigidity of the panel is secured while achieving a weight reduction. An automobile inner panel 2 has a plurality of sub-units 10 that each include a flange 11, an inclined wall 12 continuous with the flange 11, and a bottom portion 13 continuous with inclined wall 12 and separated from the flange 11. The bottom portions 13 and 13 of the sub-units 10 and 10 which are adjacent to each other are butted against each other and are directly continuous with each other. A maximum value of a distance D1 between two of the flanges 11 and 11 of two of the sub-units 10 and 10 in which the bottom portions 13 are arranged separated from each other and which are adjacent to each other is 250 mm or less.

A vehicle body joint structure includes: a frame member made of a metal pipe, extending from a side of a vehicle body to be inclined vertically, and configured to form a front pillar; and a body member made of a plastic composite material, including a dash connection part and a cowl connection part, joined to the frame member, and configured to cover the frame member.

A device for reinforcing a structural element in a motor vehicle including a reinforcing element, which has a longitudinal axis and which can be arranged in a cavity of the structural element. The reinforcing element includes walls which extend substantially in the direction of the longitudinal axis. The reinforcing element additionally includes at least one open side, which likewise extends in the direction of the longitudinal axis. The walls directly adjoining the open side are designed in a convergent manner in that extensions of said adjoining walls running in the direction of the open side and perpendicularly to the longitudinal axis intersect.

A cross-member structure/assembly for a vehicle providing an instrument panel is disclosed. The assembly may comprise a composite structure/assembly comprising a plastic beam structure and a metal structural support section to reinforce the plastic beam structure. The assembly may comprise a metal structural member and/or metal bracket member. The assembly may provide structural reinforcement and integrate vehicle systems/subsystems with the instrument panel. The assembly may comprise a set of sections/segments such as an arrangement of beam/structure sections, mounting sections, and structural elements including members, webs, flanges, stiffeners, reinforcement, plates, walls, surfaces, etc. The assembly may comprise an intermediate structural support section configured to support the beam structure. The metal structural support section may be assembled with the plastic beam structure; the metal structural member may be formed with the plastic beam structure (e.g. insert molding, over-molding, etc.). The metal may comprise an alloy such as steel, aluminum, magnesium, etc.

A vehicle floor structure according to an aspect of the present disclosure includes a floor pan, an upper surface-side reinforcing member joined to an upper surface of the floor pan, and a lower surface-side reinforcing member joined to a lower surface of the floor pan. The floor pan is formed of a resin-coated steel plate, and a resin layer of the resin-coated steel plate includes a first resin layer formed on the upper surface of the floor pan and a second resin layer formed on a part of the lower surface of the floor pan that is in contact with the lower surface-side reinforcing member.

A vehicle floor panel is provided in which a honeycomb core made of metal sandwiched and adhered between two CFRP plates is one in which a large number of core units formed into a polygon shape are continuous within one plane so as to share a side of the polygon. Since closed-section parts formed by a hat-shaped cross section part formed along the side and one CFRP plate are continuous with each other at a vertex of the polygon of the adjacent core units, not only is it possible to lighten the weight by opening the interior of the polygon (P) shape core unit, but it is also possible to enhance the energy-absorbing performance by dispersing and transmitting a collision load inputted into one direction of the floor panel toward a plurality of other directions because the high strength load transmission path is continuous with other load transmission paths.
