場合に使用されている。 Tape-shaped prepreg is used as a molding material when molding fiber-reinforced plastics (hereinafter referred to as FRP).For example, it is used for filament winding when molding tubular bodies, or it is used as a flat plate using an automatic prepreg laminating machine. It is used for molding and laying up prepreg on curved parts.

リプレグを製造するものである。 As a method for manufacturing such a tape-like prepreg, the method described in Japanese Patent Application Laid-Open No. 52-66577 is known. That is, this method involves arranging reinforcing fibers in the form of mutually separated parallel strips on a sheet coated with a thermosetting resin in a B-stage state, and then superimposing another sheet on top of the reinforcing fibers in the form of parallel strips separated from each other. After applying pressure and heating to impregnate the reinforcing fibers with resin, one of the sheets is removed, a viscous sheet is placed on top of it, and then it is peeled off to remove the excess resin between each strip. , to produce tape-shaped prepreg.

列が乱れてしまうという欠点もあつた。 However, in the conventional method described above, not only does the arrangement of the reinforcing fibers become disordered when the viscous sheet is peeled off, but also not only the excess resin between the strips but also a part of the resin impregnated in the reinforcing fibers is removed. However, there was a drawback that a prepreg with a uniform resin content could not be obtained. Furthermore, on the end faces of the strips, the resin between the strips may not be completely removed, resulting in excess resin in these areas.
Furthermore, the above-mentioned conventional method has the disadvantage that when pressurized and heated, the reinforcing fibers in each strip spread out unstablely, and the reinforcing fibers may protrude between the strips or be disarranged.

We are here to provide you with a possible method.

P. 107, September 25, 1973, Published by Kogyo Kenkyukai Co., Ltd.) Reinforcing fibers are aligned parallel to each other in a sheet shape on a sheet supporting a thermosetting resin, and the reinforcing fibers are aligned in the direction of alignment. A step of interposing spacers at arbitrary intervals along the reinforcing fibers, and a sheet carrying or not carrying a thermosetting resin in a B-stage state is superimposed on the reinforcing fibers and heated under pressure. a step of impregnating the reinforcing fibers with the resin; a step of removing one of the sheets; a step of removing the spacer; and slitting the sheet supporting the resin-impregnated reinforcing fibers at the portion where the spacer was interposed. The present invention is characterized by a method for manufacturing a tape-like prepreg, which comprises a step of winding up the sheet or peeling off resin-impregnated reinforcing fibers from a sheet and winding it up.

The reinforcing fibers 3, 4, and 5 fed out from the reinforcing fibers 3, 4, and 5 are aligned in parallel with each other and in a sheet shape so that their fiber axes are in the running direction of the sheet 2. At this time, a plurality of (two in the example of FIG. 1) string-like spacers 6, 7 are interposed at arbitrary intervals along the direction in which the reinforcing fibers 3, 4, 5 are aligned. Through this step, as shown in FIG. 2, the reinforcing fibers 3, 4, and 5 aligned on the sheet 2 are separated by spacers 6 and 7, and are divided into three reinforcing fiber groups 8, 9, and 10. will be formed.

Together with the resin, the resin content in the tape-like prepreg is 20 to 70%.
It is adjusted to % by weight, preferably 20 to 60% by weight. Moreover, it is preferable to use release paper as the sheet. Such release paper is, for example,
Kraft paper, roll paper with a thickness of about 0.05 to 0.2 mm,
A coating layer of a filler such as clay, starch, polyethylene, or polyvinyl alcohol is provided on both sides of paper such as glassine paper, and a silicone or non-silicone mold release agent, preferably polyester, is applied on each coating layer. A mold release agent made of condensation reaction type silicone or addition reaction type silicone of dimethylsiloxane and polydimethylhydrodiene siloxane is coated. Furthermore, the reinforcing fibers may be, for example, carbon fibers, glass fibers, organic high modulus fibers (e.g.
polyaramid fiber), silicon carbide fiber,
High-strength, high-elasticity fibers such as boron fibers and alumina fibers. However, such reinforcing fibers are
It is not necessarily necessary to use only one type of reinforcing fiber, and different reinforcing fibers may be used between each reinforcing fiber group, or different reinforcing fibers may be used with regularity within the same reinforcing fiber group. Alternatively, they may be mixed by arranging them irregularly. In addition, the spacer
It is preferably in the form of a string, and strings made of paper or synthetic resin, monofilament made of synthetic fibers such as nylon, etc. can be used.

Then, as shown in FIG. 3, three groups of resin-impregnated reinforcing fibers are placed on the sheet 2, corresponding to the three groups of reinforcing fibers 8, 9, and 10, that is, three groups of reinforcing fibers separated from each other. Tape-shaped prepreg 14, 15,
16 is obtained.

In this case, both ears of the sheet 2 may be removed by slitting them at the same time. In addition, without slitting the sheet 2, the three tape-like prepregs 14, 15, and 16 are peeled off from the sheet 2, and the tape-like prepregs 14, 15, and 16 are peeled off as they are, or they are replaced with a separately prepared tape-like release paper and rolled up. Good too. Alternatively, sheets such as release paper or embossed synthetic resin film may be rolled up while being overlapped.

極端に高くなる。 In the above method, the resin applied to the sheets 2 and 12 is in an A-stage state, and the A-stage resin is applied to the sheets 2 and 12.
- It is also theoretically possible to B-stage the resin in the step of expanding the staged resin by pressure heating and impregnating it with the resin, or in a heating step provided separately from that step. However, in this case, not only is it extremely difficult to support the resin on the sheet, but also the heating and pressing process takes an extremely long time, resulting in extremely high manufacturing costs.

Spacers are interposed along the line and at arbitrary intervals, and the spacers are removed after the reinforcing fibers are expanded and impregnated with resin. Not only can disturbances be prevented, but also resin impregnation can be performed uniformly, and a homogeneous tape-like prepreg with extremely little unevenness in resin content can be obtained.
Furthermore, unlike the conventional method described above, resin is not attached and removed using an adhesive sheet, so there is no possibility of resin shortage.

On the sheet supporting the thermosetting resin in the B-stage state, reinforcing fibers are arranged parallel to each other in a sheet shape, and spacers are interposed at arbitrary intervals along the direction in which the reinforcing fibers are arranged. a step of superimposing a sheet carrying or not carrying a thermosetting resin in a B-stage state on the reinforcing fibers and impregnating the reinforcing fibers with the resin by heating under pressure; a step of removing one of the sheets; a step of removing the spacer; and slitting and winding the sheet carrying the resin-impregnated reinforcing fibers at the part where the spacer was present, or rolling the resin-impregnated reinforcing fibers from above the sheet. A method for manufacturing a tape-shaped prepreg, comprising the steps of peeling off and winding up.
