不可能となる。For this reason, a method of processing the above prepreg material using a high-speed liquid jet that does not contain abrasives can be considered, but for example, if the workpiece is made of carbon fiber reinforced plastic (hereinafter referred to as rcFRP)
If it is a prepreg material (abbreviated as J), the plate thickness that can be cut is at most 2 to 2.5 mm. Therefore, it is impossible to stack a plurality of plates at the same time and cut them efficiently, and especially when the plates are not plates, it is impossible to process them.

プレプレグ材に研磨材が残留しても研磨材が工作物と同
質の材料であるため、上記プレプレグ材を硬化処理して
得られる製品に悪影響を与えるおそれが全くない。[Function] Therefore, for example, even if abrasive remains on the prepreg material after the prepreg material is cut, since the abrasive material is the same material as the workpiece, it will not have an adverse effect on the product obtained by hardening the prepreg material. There is no risk of giving.
以下本発明をＣＦＲＰのプレプレグ材の加工に適用した
実施例につき、第１図を参照しながら説明する。An embodiment in which the present invention is applied to processing a CFRP prepreg material will be described below with reference to FIG.

されている。By the way, a mixing chamber 9 is provided near the nozzle 3 so as to surround the water jet 4, and the abrasion nozzle 5 is integrally provided in the lower part of this mixing chamber. Also mixing chamber 9
The side wall 9a is provided with a feed port 11 that serves as a supply path for the abrasive material 10 to the mixing chamber 9, and this feed port 1 is connected to a tank (not shown) for the abrasive material 10 via a hose 12. has been done.

である。Next, the abrasive material 10 is made of particles having a size of 30 to 150 μm and made of the same material as the workpiece, that is, CFRP. Also, its specific gravity is 1.76 gf/cm”
It is.

体２に送給してノズル３から噴出させ、高速の水噴流４
を作る。In order to cut the CFRP prepreg material 8 using the water jet 4 generator 6 configured as described above, first, the pressurizing device is activated and the generated high-pressure water 1 is applied to the nozzle body 2. A high-speed water jet 4 is supplied and ejected from the nozzle 3.

共にプレプレグ材８に衝突し、その結果図示のように、
プレプレグ材８は切断加工される。In this way, the inside of the mixing chamber 9 becomes negative pressure due to this water jet 4, so the abrasive material 10 is sucked into the mixing chamber 9 from the feed port 11 and mixed with the water jet 4, and the abrasive material 10 is absorbed by this water jet 4. and collides with the prepreg material 8, as shown in the figure.
The prepreg material 8 is cut.

に支障を与えることが全くなかった。Next, an example of processing conditions is shown in the table below: The thickness of the sample prepreg material 8 was 2 to 1011 mm. Further, as shown in FIG. 2, the abrasive material 10 adhered to the prepreg material 8 after the cutting process, but since the abrasive material 10 is of the same quality as the prepreg material 8, it becomes a foreign substance and causes a problem in the product after hardening. Nothing happened at all.

せ、液体噴流４と混合するようにしてもよい。Although the present invention has been described above with reference to one embodiment, the above embodiment in no way limits the present invention, and various changes can be made based on the technical idea of the present invention. For example, in the embodiment, water was used as the liquid jet 4, but it is also possible to use a liquid other than the water. Further, the abrasive material 10 is
Although the abrasive material 10 is sucked by the negative pressure created by the liquid jet 4 and mixed into the liquid jet 4 , the abrasive material 10 may be pressurized and ejected into the mixing chamber 9 to mix with the liquid jet 4 .

が異なる場合には、適切な加工条件はその都度、実施例
の場合とは異なったものになる。Furthermore, although the processing conditions are illustrated in the examples, this is an example in which the workpiece is a CFRP prepreg material with a plate thickness of 2 to 10 wm and cutting processing is performed. Therefore, if the workpiece is made of a composite material other than CFRP and the type of work is different, the appropriate machining conditions will be different each time from those in the example.

上記加工能率の向上によって、たとえば板材の切断加工
に際し、複数の板材を重畳させて一度に加工することが
可能となったから、コストの低減に大きく寄与する。Since the present invention has the above-described configuration, (1) for example, when cutting a CFRP prepreg material, even if abrasives get mixed into the prepreg material and stick to it during processing, this becomes a foreign substance and does not affect the product. There is no risk of any adverse effects. Furthermore, due to the action of the abrasive, the processing efficiency of the composite material is improved several times as much as when no abrasive is used. Also, (2),
Due to the improvement in processing efficiency, for example, when cutting a plate material, it has become possible to overlap a plurality of plate materials and process them at once, which greatly contributes to cost reduction.
