Title of the Invention
NON-ASBESTOS TYPE FRICTION MATERIAL Background of the Invention (1) Field of the Invention
The present invention relates to a non-asbestos type friction material as a brake pad, a brake lining, a clutch facing, etc. for vehicles, industrial machinery, etc. more particularly, the present invention relates to a high performance non-asbestos type friction material excellent in strength and friction property and low in damage of brake drum or brake disc rotor, etc.
(2) Prior Art
Many of conventional friction materials use asbestos as a main component. However, a requirement for non-asbestos type friction material having a higher performance than asbestos type is increasing for the following two reasons. One is that the dust unavoidably generated from asbestos was found to be harmful to human health and consequently the use of asbestos is being regulated. The other is that a friction material having a higher performance than asbestos type is being needed as vehicles, etc. are being made to have a higher performance.
Hence, in recent years, a number of proposals have been made on nonasbestos type friction materials., and many of them use, as a base component, an organic fiber such as 1 an aramid fiber, or an inorganic fiber such as glass fiber, carbon fiber, metallic fiber or the like.
However, conventional friction materials using, as a main reinforcing fiber, an aramid fiber, a glass fiber, a carbon fiber or a metallic fiber have had various problems.
These problems are described on the cases where said friction materials are used in brake pads for vehicles, etc. In friction materials using an aramid fiber, the continuous use of brake increases the surface temperature of friction material, causing the thermal decomposition of aramid fiber and resultant reduction in strength and friction coefficient. In friction materials using a glass fiber, there occurs the falling-off of glass fiber at high temperatures, increasing the amount of wear. Friction materials using a metallic fiber such as steel fiber, copper fiber or the like, although they are excellent in anti-wear property, strength, etc., also have problems. That is, as the temperature goes higher, their friction coefficient (i.e.their effect) becomes abnormally high; their volume increases and their thermal conductivity becomes higher, and accordingly, they may invite burning at high temperatures. Further, the friction materials using a glass fiber or a metallic fiber have a fear of damaging or grinding the brake drum or brake disc rotor, etc.
Meanwhile, when a carbon fiber is used as a reinforcing fiber, it is anticipated that owing to the high reinforcing effect and lubricity of the carbon fiber, there can be obtained a friction material excellent in heat resistance and low in damaging or grinding of brake drum or 2 i 1 1 1 brake disc rotor, etc. However, when a carbon fiber is used in such a large amount that the above-mentioned effect can be obtained actually, there occurs abnormal reduction in friction coefficient owing to the high lubricity effect. Such friction materials using a carbon fiber in a large amount find practical applications as a C/C composite only in brakes for high-speed vehicles such as aeroplanes, racing cars and the like; they have been considered to be inapplicable to automobiles, etc. which are often operated at low speeds, because of their very low friction coefficient and higher wear at low speeds.
There were also proposed friction materials using a material other than mentioned above. Many of them, however, are not sufficient in anti-wear property at high teinperatures of 4000C or more as well as in hightemperature properties, or are instable in frictional behavior.
Summary of the Invention
The present invention has been made in order to solve the above-mentioned problems of conventional non-asbestos type friction materials and provide a non-asbestos type friction material which has excellent anti-wear property and stable friction property not only at ordinary use temperatures but also at high temperatures of 4000C or more, which is low in damage of brake drum or brake disc rotor, etc, and which has high strength.
In order to achieve the above object, the present invention provides a non-asbestos type friction material comprising a reinforcing fiber other than asbestos, a binder 3 -1 such as phenolic resin or the like and a friction-controlling agent such as barium sulfate or the like, wherein part of the reinforcing fiber is a polyacrylonitrile-based special carbon fiber.
Detailed Description of the Invention
The present invention is hereinafter described in de- tail.
In the present invention, as the reinforcing fiber other than asbestos, there is used, for example, one fiber selected from organic fibers (e.g. aramid fiber, acrylic fiber. phenolic fiber, polyvinyl alcohol fiber, cellulose fiber), inorganic fibers (e.g. glass fiber, ceramic fiber, carbon fiber) and metallic fibers (e.g. steel fiber, copper fiber, bronze fiber), or their mixture. These fibers are the same as used in conventional fiber materials.
The present invention is characterized in that part of the reinforcing fiber is a polyacrylonitrile (hereinafter referred to as PAW-based special carbon fiber.
The "PAN-based special carbon fiber" used in the present invention refers to a fiber obtained by spinning PAN, subjecting the resulting PAN fiber to a pretreatment (burning at 200-3000C in air) to obtain a flame- retardant oxidized PAN fiber, and carbonizing the fiber in an inert gas at 800-1,OOOOC so that the resulting carbon fiber has a specific gravity of 1.6-1.74.
In the PAN-based carbon fiber, the specific gravity indicates the carbonization degree of the fiber. In the present invention, this PANbased carbon fiber is prefer- 4 ably used in an amount of 0.5-70% by volume based on the total of friction material.
PAN-based ordinary carbon fibers are obtained by carbonizing the abovementioned oxidized PAN fiber at high temperatures of 1,000-1,5000C and have a specific gravity of 1.75-1.80.
As the binder, there are used, for example, thermosetting resins such as phenolic resin and the like; as the friction-controlling agent, there are used, for example, cashew dust, barium sulfate, calcium carbonate, etc. These are widely used in conventional friction materials.
As described above, the non-asbestos type friction material of the present invention comprises a PAN-based special carbon fiber as part of the reinforcing fiber. This PAN-based carbon fiber, when used as a reinforcing fiber in a friction material, does not significantly reduce the friction coefficient of the friction material, as compared with a PAN- based ordinary carbon fiber of higher specific gravity. Accordingly, it can be used in a large amount and yet can show excellent effects (e.g. reinforcing effect); moreover, the resulting friction material can exhibit properties at least equal to those of asbestos type friction materials or other non-asbestos type friction materials.
The present invention is hereinafter described in more detail by way of Examples.
1 Examples
Thermex (brand name) (a PAN-based special carbon fiber having a specific gravity of 1.65 manufactured by TOHORAYON CO., LTD.) was uniformly mixed with other components in proportions shown in Table 1, by means of a mixer. The resulting mixture was subjected to compression molding in a mold at a temperature of 1500C at a pressure of 300 kg/cm 2 for 9 minutes to obtain friction materials of Examples A to F. (The numerical f igures in Table 1 are shown by % by volume.) The same operation as above was conducted except that the PAN-based special carbon fiber used in each of Examples A to F was replaced by a PAN-based ordinary carbon fiber having a specific gravity of 1.79, to obtain friction materials of Comparative Examples a to f shown in Table 2.
Further, the same operation as above was conducted except that the PANbased special carbon fiber or PAN-based ordinary carbon fiber, aramid fiber and bronze fiber used in each of Examples A to D and each of Comparative Examples a to d were replaced by asbestos, the same aramid fiber, the same copper fiber, or the same aramid fiber and the same bronze fiber, to obtain friction materials of Comparative Examples 9 to j shown in Table 3.

Further, a sample was cut out from each friction material after the above test and subjected to a shear test specified by JASO C444-78 'Thysical Properties of Friction Materials Test Procedure".
In Tables 4 to 6, there are shown the results of the above two tests, i.e. (a) friction coefficients in the fade test when each friction material showed surface temperatures of 1000C, 2000C, 3000C, 4000C and 4500C, (b) the wear amount of each friction material after said test, (c) the 8 A J condition of brake drum or brake disc rotor, etc after said test, and (d) the shear strength of each friction material after said test.
Using three other PAN-based special carbon fibers having specific gravities of i.68, 1.70 and 1.72, there were prepared friction materials in the same manner as above; they were subjected to the same tests; the results were almost the same as in Tables 4 to 6.
As described above, the non-asbestos type friction material of the present invention can be advantageously used as a brake pad, a brake lining, a clutch facing, etc. for vehicles, industrial machinery, etc.
