Abstract
A metal panel having a coupling hole formed therein; A connecting portion having a pipe-shaped coupling portion extending in the longitudinal direction and a flange formed to protrude outward along the outer periphery of the coupling portion, the flange having the same diameter as the coupling hole of the metal panel; A fixing part for fixing the metal panel and the flange to each other at the edge of the flange; And a plurality of reinforcing fiber sheets laminated on the metal panel.
Description
The present invention can stably insert a connecting port such as a nut into a composite panel in which a metal panel and a reinforcing fiber sheet are laminated, secure a bonding strength effectively even in an inserted state, To a reinforced fiber composite panel which is vertically inserted.
Recently, as interest in lightweight materials has increased, research on composites using carbon fiber has been actively carried out. Carbon fiber has higher tensile strength and light weight than metal, but it has weak point of bending strength.
Techniques for joining such composite materials with other parts by inserting a nut or bolt or the like are also introduced.
In the conventional case, a method of making a stirrer bar is introduced as an example. This is because a wire is inserted into a groove formed in the longitudinal direction of the lower mold, a joint nut is inserted into both ends of the groove, the end of the wire is inserted into the groove formed in the rear surface of the joint nut, A first step of foaming the polyurethane surrounding the joint nut and covering the upper mold on the lower mold to form a polyurethane core; A second step of braiding carbon fibers on the outer circumferential surface of the polyurethane core; A third step of infiltrating the resin into the braided carbon fibers, and a fourth step of fastening the joint bolts to the joint nuts.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above problems, and it is an object of the present invention to stably insert a connection port such as a nut into a composite panel in which a metal panel and a reinforcing fiber sheet are laminated, And to provide a reinforced fiber composite panel having a vertically inserted connector having a relatively easy insert process.
According to another aspect of the present invention, there is provided a reinforced fiber composite panel having a connector insert vertically inserted therein. The flange being formed to protrude outward along the outer periphery of the coupling portion and extending in the longitudinal direction, the flange having the same diameter as the coupling hole of the metal panel, wherein when the flange is inserted into the coupling hole, A connector coplanar with the panel; A fixing part for fixing the metal panel and the flange to each other at the edge of the flange; And a plurality of reinforcing fiber sheets which are composed of a plurality of layers laminated on the metal panel and in which through holes are formed at the same positions as the coupling holes of the metal panel and the connecting holes pass through the through holes when stacked on the metal panel do.
The engaging hole and the flange are in the shape of a circle having the same diameter, and the outer peripheral surface can be in contact with the inner peripheral surface of the engaging hole in a state where the flange is fitted in the engaging hole.
The fixing portion may be a spot welding portion connecting the metal panel and the flange.
The metal panel and the flange may be the same in thickness.
The metal panel and the connector may be formed of the same material.
The extended length of the connector is formed to be equal to the thickness of the composite panel in which the metal panel and the reinforcing fiber sheet are combined, so that the end of the connector can be positioned on the plane formed by the outermost reinforcing fiber sheet.
The connecting port may be constituted by an upper fitting portion extending upward in a pipe shape with respect to the flange and a lower fitting portion extending downward in a pipe shape with respect to the flange.
The upper and lower coupling portions may be formed in the shape of a pipe having the same diameter, and the inner side of the upper and lower coupling portions may be hollowed together.
The upper joining portion protrudes upward from the metal panel, the lower joining portion protrudes downward from the metal panel, and the reinforcing fiber sheet may be laminated on the upper surface and the lower surface of the metal panel.
According to the reinforced fiber composite panel in which the connector is vertically inserted in the present invention, it is possible to stably insert a connecting port such as a nut into a composite panel in which a metal panel and a reinforcing fiber sheet are laminated, So that the insert process can be performed relatively easily.
