Abstract: Provided is a method for producing a porous copper foil. The method includes forming a release layer on a metal carrier, growing copper islands on the metal carrier formed with the release layer by electroless copper plating, forming a porous copper thin layer by copper electroplating, and peeling off the porous copper thin layer from the release layer.

Abstract: A reinforcing structure for a package tray side member provides a rigid connection between the package tray side member and a vehicle body while enabling the package tray side member to be re-positioned towards a rear end of a vehicle. The package tray side member is re-positioned so as to be located between a rear end of the vehicle and a seat belt retractor and a shock absorber. Upper and lower end portions of the package tray side member are reinforced, and are respectively coupled to a package tray side panel of a vehicle and to a floor upper side member of a floor panel of the vehicle.

Abstract: A seat back mounting structure of a vehicle body may include a side pin that is fixed on a seat back frame, a seat back bracket formed with an insertion hole through which the side pin is inserted, a fixation hole, and a guide route between the insertion hole and the fixation hole such that the side pin moves from the insertion hole to the fixation hole, and an elastic bracket including a fixation portion formed at one side thereof, the fixation portion being fixed on the seat back bracket, and a protruded portion formed at a central portion of the elastic bracket, the protruded portion reducing a width of the guide route and elastically deformed by the side pin when the side pin moves from the insertion hole to the fixation hole.

Abstract: A structure of a rear package tray for a vehicle, which is mounted on body panels which vertically stand at both sides of a floor panel and positioned between an interior room and a trunk room of a vehicle. The structure includes: a side member mounted on the body panel with a front side member which is positioned at a relatively front side, and a rear side member which is positioned at a relatively rear side, coupled to each other; an upper member disposed at an upper side of the side member in a horizontal direction of a vehicle body; and a support member having one side connected to the upper member and the other side connected to the side member with an inclination to be spaced apart from a connection portion of the side member and the upper member. A reinforcing flange protrudes in a horizontal direction along one side edge of the support member.

Abstract: A roof-side structure includes a roof center rail which is engaged with the bottom surface of a roof panel and one end of which extends to a position of a curtain airbag, a roof rail gusset engaged between a roof side outer reinforcing panel and the one end of the roof center rail, and a side inner panel which is engaged with the roof rail gusset in a state that a curtain airbag is engaged with a front side of the one end of the roof center rail. Accordingly, since the roof rail gusset is arranged inside of the side inner panel so that it does not interfere with the curtain airbag, a layout of the curtain airbag is advantageous. Also, since it is not required to bend the roof rail gusset to connect the roof center rail and the side inner panel, in the event a broadside collision is applied to a vehicle, the roof rail gusset remains unbroken, and thus the rigidity of the roof center rail can be sufficiently reinforced.
