It is easy to manufacture long composite materials by applying electricity directly to rolls such as iC or W, heating the metal and fibers that form the matrix between the roll contacts with Joule heat, and at the same time applying pressure with the roll itself.

とＡＱの反応により炭化物が生成し１強度が劣化する。Normally, as mentioned above, the metal and fiber that become the matrix by the above manufacturing method are coated with metal in advance before being composited, as shown in Figure 1, and bundled into multiple fibers, for example, as shown in Figure 2. Compounded. However, the first
The bundle of metal coatings shown in the figure is substantially free from fiber disorder or non-uniformity of the metal coating thickness, which results in local differences in electrical resistance. As a result, when electricity is passed through the roll, the heat generation is partially different from the original compounding temperature. That is, when manufacturing AQ-C fiber composite material according to Japanese Patent Application No. 59-55705, Afl before being composited.
Due to the electrical resistance of the coated C fiber bundle, during compositing, if the AQ coated C fiber bundle is lower than the original composite temperature, poor bonding between AQ co-coatings and fiber breakage will easily occur, and the original Higher than the composite temperature, C
Due to the reaction between AQ and AQ, carbide is generated and the strength deteriorates.
昭５９−５５７０５は、その点の配慮がされておらずそ

ＡＱ４Ｃｓの生成による折損が発生することがあった。In 1984-55705, this point was not taken into consideration, and as a result, during the compositing process of lengthening, non-composite formation or breakage due to the formation of carbide AQ4Cs sometimes occurred.

力が負荷される。Figure 3 shows a long AQ-C according to Japanese Patent Application No. 59-5705.
The tension of the Afi-coated C fiber 1 is determined by the rotational friction force between the AQ coating C fiber and the winding bobbin 2 and the rotational force of the upper roll 3 and lower roll 4. Tension is generated in the C fibers for the purpose of giving them straightness. Also, the tension between the bobbin and the roll is maintained by the spring 5.
Typically, an arbitrary tension is applied depending on the strength of the supplied fiber bundle.

。The AQ cocoing C fibers interposed between the rolls generate Joule heat due to the current flowing through the rolls and the AQ cocoing C fibers through the current terminal 5 due to the small area of the roll contact and the resistance of the raw material itself. This allows A
A composite temperature of 450 to 500''C of Q and C fibers is instantaneously generated, and the original composite temperature is given while following the feeding speed of AQ cocoing C fibers due to the rotation of the roll.
一方、ＡｆｉコーティングＣ繊維にががる圧力６は不可
欠で、加圧力がないと、繊維同志が離れ。On the other hand, the pressure 6 that causes the Afi coating C fibers to separate is essential; if there is no pressure, the fibers will separate.

The pressure is determined by the fiber bundle supplied, but basically the fiber bundle is generated due to substantial non-uniformity in the AQ coating thickness or due to substantial crossing of the fibers. A constant load method is adopted to eliminate pressure unevenness.

第３図７のＡＱ−Ｃｗｉ維複合材は、折損し、安定した
長尺品が製造が難しくなる。By the above method, a long AQ-CFRM 7 can be manufactured. However, the states of the AQ cocoing C1 and M fiber bundles are non-uniform, and the contact states of the C fibers are different. As a result, the electrical resistance of the C1a fiber bundles is partially different. That is, the Joule heat generated in the AQ-coated C fiber bundle between the rolls is different. As a result, carbide formation or uncompounded parts occur, and during continuous compounding,
The AQ-Cwi fiber composite material shown in FIG. 37 is prone to breakage, making it difficult to manufacture stable long products.

できる。That is, in order to stably produce a long Aα-〇 fiber composite material, it is necessary to make the electrical resistance of the AQ coated C fiber bundle uniform. As a method, up to 50
Compositeization is performed at a low temperature of 0°C, preferably 450-300°C, by the method shown in FIG. In such low humidity,
There is no generation of carbides, and the contact between the AQ coatings is uniform over the entire surface due to the pressurization of the rolls. This means that the electrical resistance of the He〇-coated C fiber itself is made uniform. However, at such low temperatures,
There is a cavity in the AQ matrix. Therefore, by performing composite formation again at a predetermined temperature of 500 to 450°C, the cavities disappear. As described above, in the method for manufacturing a long AQ-C fiber composite material using energized rolls, in order to equalize the electrical resistance of the A2 coated C fibers, the rolls are rolled at least twice at a temperature of at least 500°C or less. By passing through the fibers, a long AI2-CMl fiber composite material can be stably produced.

A fine line-shaped AQ-C fiber composite material is prepared in advance, and a plurality of these are arranged in one direction and composited again with a predetermined width. Thereby, a stable wide AQ-C fiber composite material can be manufactured.

Ru. That is, a bundle of C fibers coated with AQ is made into a woven fabric (for example, by hand weaving), and after stacking a plurality of these, the electrical resistance is made uniform at a temperature of 500°C or less, and then the electrical resistance is made uniform again. A reticulated Afl-C fiber composite material can be produced by compositing at .degree.
