[Detailed Description of the Invention] L1 Emperor Plate ±1 The present invention is applied to plate-like structural materials that can reduce the number of processing steps and have great strength and rigidity per weight of 8! &! This paper describes a method of molding a fiber-reinforced reinforcing fiber and a molding device therefor.

, V, 1,1-fcrd, one side of a thick plate made of a light alloy or a titanium alloy shown in Figure 22 as a plate-like structural material with high strength and rigidity. Conventionally, there is a method in which the reinforcing rib part 02 is formed integrally with the flat plate part 01 by cutting out the plate part 01, but the cutting cost is too large, there are many parts that are wasted, and the machining time is longer. ~ High is unavoidable.

Further, as shown in FIG. 23, a light alloy thin plate is curved in one direction at regular intervals, the curved tip 04 is formed into a hollow cylindrical shape, and the light alloy is bent so that both adjacent parts 05 are in contact with each other. There is a plate-like structural material in which a reinforcing material 03 is formed by molding a thin alloy plate, a flat part 06 of this reinforcing material 03 is applied to a light alloy flat plate 01, and both are joined together by spot welding or adhesive.

However, when spot welding is performed using the root-like structure material shown in Fig. 23, welding marks remain on the flat plate 07, which is unfavorable in terms of appearance, and the joint is discontinuous, so it is difficult to improve strength and rigidity. disadvantageous and unreliable.

Furthermore, since the reinforcing material 03 must be formed by press forming a light alloy thin plate, the process becomes complicated and the equipment becomes large. O
It has been difficult to efficiently produce a wide variety of root-like structural materials with short distances between , '+.

The present invention relates to an improvement of a root-like structural material that overcomes these difficulties, and is made so that the central part in the width direction is thin and the opposite ends in the width direction are perpendicular to the outside.

A cylindrical core is placed on the widthwise center of the fiber-reinforced molding material, and while the cylindrical core is pressed against the fiber-reinforced molding material, the cylindrical core is reinforced with the m groups. The flexible reinforcing material forming jig is curved so as to surround the fiber-reinforced molding material with the molding material and bond both sides of the fiber-reinforced molding material to each other, and then the flexible reinforcing material molding jig is curved so as to surround the fiber-reinforced molding material at both ends thereof. A fiber-reinforced resin plate-like structural material is constructed by bending both ends of the reinforced molding material at right angles so as to be joined to both ends of the reinforcing molding jig in the 11] direction. I can do it.

In this way, the tl [reinforced molding material is wrapped around the cylindrical core, and the flexible reinforcing material molding jig is placed over the outer periphery of the reinforcing material, and the reinforcing material having a bi-shaped cross section is formed by volatilizing it. It can be produced very easily.

Since the forming apparatus for reinforcing material for a plate-like structural material is constituted by the bending pressure welding means for pressing the end portions against the right-angled side edges of the forming jig, the forming of the reinforcing material can be performed by using the forming material:N. The method can be implemented.

J shown in FIG. 19: With the forming jig 1o in the unfolded state, the reinforcing material 4 is placed on the forming jig 10, and then the cylindrical core 16 is inserted into the lower end recess of the core support member 17. Groove 6
1, the tilting frame 50 is vertically erected by extending the tilting 1 pulling 7 cylinder 53.
7. After extending the cylinder 57 to a length U and lowering the core support member 17 and bringing the cylindrical core 1G into contact with the reinforcing material 4 on the forming jig 10, the jig driving air cylinder 45 is gradually extended. As shown in FIG. 20, the swing slider 3
8 is lifted upward, the jig support member 14 is laid down horizontally, and the reinforcing material 4 is wrapped around the outer periphery of the cylindrical core 16 by the forming jig 10.

Next, the core lifter X7 cylinder 57 is shortened and the core support member 17 is pulled upward, and then the jig driving air cylinder 45 is roughly extended and the pressing air cylinder 58 is extended. 7 is joined to the phase n, and the bent ends 5 on both sides are pressed against the forming jig 1 by the bending pressing member 18.

Additionally, by eliminating manual work and automating it, errors by workers can be reduced and quality stability can be improved.

Furthermore, since the reinforcing material 4 is not continuous, the reinforcing material 4
The spacing can be freely selected, and many types of fiber-reinforced resin plate-like structural members 1 can be easily produced without increasing costs.

Fiber-reinforced resin plate JM shown in Figures 1 and 14
In the structural material, the joint portions 7 on both sides of the reinforcing material 4 are integrally joined to each other, and the bent ends 5 on both sides of the reinforcing material 4 are connected to the flat plate material 2.
Since it is manufactured by being integrally bonded to the surface 3 of Stress is transmitted continuously over the entire cross section without causing stress concentration, and moreover, the stress is transmitted continuously over the entire cross section without causing stress concentration, and
4 is carbon fiber, and therefore the strength and rigidity per unit of the fiber-reinforced resin plate-like structural material 1 are high.

Further, in the embodiment described above, the plate-shaped structural material 1 made of IJ and miscellaneous reinforced resin can be manufactured efficiently and at low cost without wasting materials.

Furthermore, since a flexible material is used for the cylindrical core 16 for forming the hollow cylindrical portion 6 at the top of the reinforcing material 4, the entire reinforcing material 4 is I! i This reinforcing member can be easily joined to a curved plate material that is simply curved and curved or twisted in the longitudinal direction of the reinforcing member 4 and in a direction perpendicular to this, so a plate-like structural material with a complicated curve can be manufactured.

In the above embodiment, the fiber-reinforced molding material of the flat plate material 2 and the reinforcing material 4 was prepreg, but a resin mixture based on a resin such as thickened unsaturated polyester resin was used as a matte carbon fiber or glass. SHC obtained by impregnating the fiber (SheetHoldin() C01p0
1Jnd).

By carrying out the above-mentioned forming method in which the head fibers are connected and a single piece of cloth is folded using the reinforcing material forming apparatus of the present invention, a plate-like structural material having a two-shaped cross section can be obtained.
