The cowl cross bar assembly includes a first pipe and a second pipe that are hollow and disposed laterally inside a chassis, a dash mounting member disposed between both ends of the first pipe, and a stiffener accommodated in an internal space of the dash mounting member and configured to absorb collision energy generated in a collision of a vehicle.

A cowl cross bar assembly of reduced weight and increased stiffness. The cowl cross bar assembly includes a first pipe and a second pipe which are hollow and disposed laterally inside a chassis, pipe caps coupled to one end of the first pipe and the second pipe, and pipe stiffeners accommodated in the first pipe and the second pipe and configured to absorb collision energy generated in a collision of a vehicle.

A chassis for an electric vehicle, comprises a left side frame and a right side frame made of a material comprising carbon fibre, at least one lower structural member connected with and extending across the left side frame and the right side frame, and a plurality of upper structural members connected with and extending across the left side frame and the right side frame. The lower structural member provides support for one or more rechargeable battery packs.

A hybrid structural assembly includes a vehicle structural member extending from a first end to a second end, and a composite reinforcement member attached to the vehicle structural member between the first and second ends of the vehicle structural member. The composite reinforcement member being formed by a continuous method and cut to a predetermined length extending from the first end to the second end.

An instrument panel assembly comprising: a crossmember (2) including a first beam (4) and a second beam (6), a center support assembly (8) with a first structural arm (30), a second structural arm (32), and a center support bracket (34); wherein the first beam (4) is hollow and has a larger diameter than the second beam (6), and the second beam (6) is adapted to slide into the first beam (4).

Provided is a body side panel body side panel (BP) including one metal panel (P1); another metal panel (P2) that forms a space (A) between the one metal panel (P1) and the other metal panel (P2); a resin member (R) that is molded integrally with the one metal panel (P1). The resin member (R) includes link ribs (11A, 11B, 12A, and 12B) that continuously extend respectively along a front edge and a rear edge of a center pillar portion (CP), and along an upper edge and a lower edge of a sill portion (SL), and includes a lower intersection rib (14) that is arranged in an intersection region where a lower end portion of the center pillar portion (CP) and the sill portion (SL) intersect with each other. A clearance (S1) from a distal end portion of each of the link ribs (11A, 11B, 12A, and 12B) to the other metal panel (P2) is smaller than a clearance (S2) from a distal end portion of the intersection rib (14) to the other metal panel (P2). Impact energy in case of side collision is released in two steps. With this, an impact absorbing function is enhanced.

An embodiment includes a method of manufacturing a plastic composite material panel. A gel type plastic composite material is loaded onto a fixed die having a first molding surface of a flat shape for molding a material filling portion and a second molding surface for molding an outer plate portion. A first movable die having a third molding surface for molding the material filling portion and a fourth molding surface for molding the outer plate portion is combined with a second movable die having a molding groove for molding the material filling portion to the fixed die. The outer plate portion is formed by the second and fourth molding surfaces and the material filling portion is integrally formed with the outer plate portion by the first and third molding surfaces and the molding groove. The material filling portion is thicker than the outer plate portion.

Presented are multilayer composite panels for motor vehicles, methods for making/using such panels, and motor vehicles with transparent composite roof panels having localized reinforcement features. A sandwich-type multilayer composite panel contains one or more exterior layers each including a transparent rigid material, one or more bonding layers each including a transparent adhesive material, and one or more structural reinforcement layers each including a fiber-reinforced polymer material. Each structural reinforcement layer may be attached directly to a bonding layer and/or exterior layer. The composite panel may also include one or more IR-reflective layers, one or more light-absorbing sunshade layers, and one or more insulating low-k layers. The fibers of each structural reinforcement layer are localized to a discrete region within the composite panel's plan-view profile. This region has laterally spaced side rails extending along the length of the multilayer body panel, and one or more transverse crossmembers connecting the side rails.

A roof panel module includes: a vehicle roof panel formed by resin; a radio wave shielding part provided in a corresponding region of the vehicle roof panel; and a conductive elastic member having conductivity, wherein the conductive elastic member is provided along at least a part of an edge of the vehicle roof panel.

An automotive crashworthiness energy absorption part for being provided on a front part or a rear part of an automotive body includes: a tubular member formed using a hat-shaped section part including a top portion and a side-wall portion; a coating part configured to form a coating film arranged with a gap of 0.2 mm to 3 mm from an inner surface of the top portion, an inner surface of the side-wall portion, and an inner surface of a corner portion, on a portion including the corner portion connecting the top portion to the side-wall portion in the inner surfaces of the top portion and the side-wall portion, the coating part being made of a material having strength lower than the tubular member; and a coating film of an electrodeposition paint formed in the gap.
