炭素繊維や導電性に優れた黒鉛繊維があげられる。<Prior art> Carbonaceous material whose main component is carbon has heat resistance, corrosion resistance,
Because it has excellent properties such as electrical conductivity, mechanical properties (strength, elastic modulus), adsorption, X-ray transparency, vibration damping properties, and abrasion resistance, many types of fibers have been developed depending on the purpose. used in Examples include carbon fibers with excellent mechanical properties, flame-resistant fibers with excellent thermal oxidation resistance, activated carbon fibers with excellent adsorption properties, and graphite fibers with excellent conductivity.

ミックス等をマトリックスとして炭素繊維を内部に配列
、分散させた炭素繊維強化材料は後者の例である。When using these carbonaceous fibers, depending on the purpose, they may be used in a form close to the fiber alone, or they may be used as a composite material in which they are combined with other materials. For example, when used for applications such as heat insulating materials, adsorbents, filters, and sound absorbing materials, the former form is used, and is reinforced with carbon fibers in which carbon fibers are arranged and dispersed in a matrix of 41 fat, carbon, metal, ceramics, etc. Materials are an example of the latter.

うことは出来なかった。However, although carbon fibers are composited with other materials, the form used is the former, that is, the form of carbon fiber reinforced materials described above is inappropriate in response to the request to be equivalent to the case of unique fibers. , several improvements have been attempted so far. For example, coating the fiber surface with carbon, ceramic, or metal using a plating method or CVD (chemical vapor deposition) method, or grafting a polymer onto the fiber surface, etc., have been carried out. However, with these conventional technologies, the materials that can be composited are limited depending on the processing method, and it is difficult to mass-produce at low cost. It was not possible to easily form a compound by sufficiently contacting with.

れた。On the other hand, activated carbon fibers (A-15 manufactured by Ador Co., Ltd.) that had been pretreated with ozone (concentration 4000 ppm, flow rate 31/min) for 30 minutes, treated with an aqueous solution of a 1% concentration Nlankanobbling agent, and dried. The mixing powder is brought into contact with 200
The carbonaceous composite fibers were held for 2 hours at 100° C. and subjected to calf niering, and finally carbonaceous composite fibers were obtained in which 2 parts by weight of binder and 12 parts by weight of graphite powder were attached to the fiber surface based on 100 parts by weight of activated carbon fibers.

。(Status of adhesion of particles) The surface of the obtained activated carbon fiber was observed using SEM to check the adhesion status of particles. As shown in Figure 3, there was no agglomeration of the particles themselves, and they were adhered to the surface sufficiently homogeneously. confirmed.

In other words, most of the particles of powdered substances themselves are attached to the carbon fibers independently without major agglomeration, so there is sufficient contact between the particles and the atmosphere, and it also has the unique functions of powdered substances. It can be used as a carbonaceous fiber.
