There is a C component. The density of C/C component is 1.7
Although carbon fiber is lightweight at ~1.9, it is expensive, and when manufacturing structures, it is necessary to layer woven fabrics with fibers arranged two-dimensionally, such as plain weave or satin weave, or to use three-dimensional woven fabrics. The use of cloth makes it even more expensive. Furthermore, since the C/C component is entirely composed of carbon-based materials, it has the disadvantage of being oxidized and consumed in air when exposed to high-speed, high-load conditions and the temperature of the friction surface exceeds 400°C.

The woven fabric was dipped in varnish (manufactured by Kogyo, PR524) to sufficiently penetrate the varnish. Next, the jig was placed in an autoclave, and an air pressure of 6 kg/cm2 was applied to keep it at 160°C for 6 hours to reduce the weight of the woven fabric/carbon source to 6 kg/cm2.
It was made into a molded body of 0/40. Table 3 shows the properties of this molded product.

Raise the temperature from room temperature to 200℃ at a rate of 5℃ per hour, hold at 200℃ for 5 hours, and increase the temperature from 200℃ to 500℃ by 10℃ per hour.
After raising the temperature at 500℃ for 10 hours, the temperature was increased from 500℃ to 9
A method was used in which the temperature was raised at a rate of 5°C per hour up to 00°C and held at 900°C for 10 hours. This fired product was placed in a pressurized impregnated layer, the pressure was reduced to 5 mmHg, and tar pitch (PK-L, manufactured by Kawasaki Steel Corporation) heated and melted at 350°C was injected into the layer to return to normal pressure, and the pressure was further reduced to 6 kg/cm2. Apply air pressure and hold it for 1 hour, then take it out after cooling, put it in an iron baking can, and place it in the surrounding area.
Filled with carbon grains of ~2 mmφ, heated from room temperature to 500°C at a rate of 10°C per hour, held at 500°C for 10 hours,
The temperature was raised from 0°C to 900°C at a rate of 5°C per hour and held at 900°C for 10 hours to burn and carbonize the tar pitch. This tar pitch impregnation and calcined carbonization was repeated two more times to obtain a 50/50 ceramic fiber/carbon matrix composite by weight. The properties of this composite are shown in Table 3.

ので廉価な複合材料が得られる。[Effects of the Invention] According to the present invention, since the skeleton is composed of ceramic fiber woven fabric, it is heavier than a C/C component but much lighter than cast iron, and has better oxidation and wear resistance than carbon fiber. Because the carbon matrix is coated by using ceramic fibers and impregnated with metal, it is superior to C/C components in terms of heat resistance including oxidation and wear resistance, and it also uses cheaper cotton-like ceramic fibers. This makes it possible to obtain inexpensive composite materials.
