高くつく等の欠点もあつた。[Problems to be Solved by the Invention] However, such conventional C/C composite joining means can be damaged due to, for example, burning of screws or embrittlement in an inert gas atmosphere such as nitrogen gas, or damage to the joining base material. There were drawbacks such as the joint becoming loose due to the difference in thermal expansion between the two. Furthermore, the above-mentioned bonding members tend to creep when used for long periods of time under high temperatures, and since they have a higher specific gravity than C/C composites, handling properties are reduced due to the increased weight of the bonded parts, and the bonding materials are expensive, making it difficult to bond them. There were also drawbacks such as high cost.

施すことによつて達成できる。[Means for Solving the Problems] The above-mentioned problem to be solved by the present invention is to bond composite materials substantially made of carbonaceous materials reinforced with carbon fibers to each other by attaching carbon fibers to the joints using a graphite adhesive. This can be achieved by winding the material and then subjecting it to heat treatment.
以下、本発明を図面を参照しながら具体的に説
明する。 Hereinafter, the present invention will be specifically explained with reference to the drawings.
第１図は本発明にかかるＣ／Ｃコンポジツト接
合例を示す概略図であり、第２図は第１図のＡ−
Ａ断面図を示す。図中、１，１′はＣ／Ｃコンポ

A sectional view is shown. In the figure, 1 and 1' are C/C composites, 2 is a joint surface, and 3 is carbon fiber.

である。 As shown, C/C composite 1, 1'
When bonding, first, a graphite adhesive (not shown) is applied to the bonding portion (particularly the bonding surface) 2 and bonding is performed. Graphite adhesive is further applied on top of it and carbon fiber is wrapped around it to secure the joint. In other words, the carbon fibers are wrapped around the joint with sufficient strength, and at the same time, the graphite adhesive bonds the C/C composites to each other and the C/C composites to the carbon fibers.
なお、上記Ｃ／Ｃコンポジツト１，１′の接合

100〜150℃、熱処理時間として約３〜４時間が好
ましい範囲である。 Next, the bonded portion after adhesive fixation requires heat treatment of curing and baking to harden the graphite adhesive. Since this curing is for the purpose of drying the graphite adhesive, the heat treatment temperature and heat treatment time can be set appropriately depending on the material of the adhesive, but the heat treatment temperature should be approx.
The preferable range is 100 to 150°C and a heat treatment time of about 3 to 4 hours.
接合部分の養生が終れば、その後、N2、Ar、
He等の不活性雰囲気またはH2等の還元雰囲気中

The temperature is gradually raised to the working temperature of the C/C composite (approximately 1400°C or higher) in an inert atmosphere such as He or a reducing atmosphere such as H2 , and firing is performed for approximately 0.5 hours. Through these curing and firing processes, the C/C composite joint becomes lightweight and has excellent durability.

囲気中で約3000℃まで徐々に焼成した。Example Each joint surface of C/C composite (20 mm square x 2000 mm) was cut by 300 mm in the length direction and 10 mm in the thickness direction. Apply Graphite adhesive (New Coat GC) to the cut surface and stick them together. Afterwards, apply graphite adhesive to the surface of the joint and use carbon fiber strands (approximately 12,000 denier).
