であるチタン酸アルカリ繊維に着目し、導電性チタン酸
アルカリ繊維の開発を図り、種々提案してきた。In these conventional technologies, metal fibers are susceptible to deterioration due to the environment in which they are used, such as oxidative corrosion, and carbonaceous materials are suitable as highly conductive materials, but it is difficult to uniformly align the M and heel lengths of carbon fibers. However, since the aspect ratio is uneven, the molding processability is poor, and the surface smoothness and abrasiveness of the molded product are poor.For conductive polymer materials, the molding processability is insufficient, and it is difficult to directly mold the product. It is difficult to make, and there are no fiber-shaped products that can be used in common with pond plastics. However, in addition to the conductivity of carbon materials, these conductive polymer materials are electron transfer conductive materials due to the bonds between carbon molecules, and are expected to be a future technology because they can be made highly conductive with doping agents. Attempts have also been made to deposit conductive polymer films on the surfaces of various substrates, such as films coated with conductive polymer films,
lam etc. are also being proposed. As a technology separate from these conventional technologies, the present inventor focused on alkali titanate fiber, which is a functional filler that provides excellent reinforcing properties, heat resistance, and surface smoothness as a filler for composite materials. We have been developing alkali titanate fibers and have made various proposals.

5129, by firing a mixture consisting of an alkali titanate and a carbon material in a non-oxidizing atmosphere, the alkali titanate is reduced and, at the same time, a portion of the alkali titanate is precipitated as a carbon material on the surface of the alkali titanate. Discloses a technology to obtain conductive alkali titanate Wj and fibers by utilizing this, and furthermore, as an improvement method of these technologies, fibers! We have developed a manufacturing technology for conductive materials in which a carbonaceous film is formed by treating the surface of a material with a hydrocarbon liquid and then firing it in a non-oxidizing atmosphere. By using the method, a homogeneous carbon deposited film can be obtained depending on the reaction conditions, and the method of pre-treating the M & fiber surface with a hydrocarbon substance is more dense than the gas phase reaction, resulting in ultra-fine carbon particles and excellent conductivity. However, in both methods, grain boundaries exist in the deposited carbon, making it difficult to obtain the highly conductive region that carbon fibers exhibit. is highly skilled and! ! It was necessary to manage the shipping process.

ルカリ土類金属織維等が例示される。In the present invention, the fibrous component is one that has a fiber shape with an aspect ratio (ratio of fiber length to fiber diameter) of 10 or more, and has excellent heat resistance because it is fired in a non-oxidizing atmosphere. Generally, it is selected from non-woven fibers, and due to the fact that it is fired in a heating kiln and workability when used as a composite material, the mm length is 1 μm-300 mm, and the fiber diameter is 0.1 μm −1. It is preferable that the fiber diameter is about mm.If the fiber diameter is too small, the reinforcing effect will be insufficient, and if the fiber length is too long, it will take a lot of effort to remove the fiber, and when used as a material for composite materials, the moldability and homogeneity will be poor. This is because as the aspect ratio decreases, the reinforcing properties tend to be insufficient.
