明に到達した。For this reason, various asbestos-free friction materials and friction materials are being studied. For example, a friction material base material containing glass fiber instead of fine asbestos (Japanese Utility Model Application Publication No. 111978/1983, Publication No. 103091 of Jitseki Sho 56-1) or a friction material (Tsubaki Seki Sho 5)
1-54144, JP-A-56-167934, and JP-A-57-3828).
These base materials for friction materials or friction materials have so far been used for clutch facings by a so-called semi-molding method mainly containing rubber. One of the reasons for this is the concept of JP-A-56-129285. In other words, when asbestos-based friction materials require flexibility, such as brake linings and clutch facings, flexibility can be ensured due to the European structure of asbestos, but non-asbestos-based friction materials containing glass fibers do not have asbestos-like properties. is inflexible and needs to be made flexible in other ways. The idea is that a rubber binder is required as a means for achieving this. However, in recent years, as car cocoons have become larger, faster, and traffic jams become more congested, the conditions for their use have become more severe.As a result, the properties required of friction materials have become increasingly strict. Semi-molded friction materials containing such materials have reached their limits in meeting required properties such as heat resistance and rotational fracture strength. For this reason, there is currently a need for special-woven friction materials molded from resin or the like. In order to give flexibility to brake linings and clutch facings, special woven friction materials are made of bulky base materials with flexible structures that are not found in conventional glass rovings, glass yarns, tapes, and cloths, such as 111978) has been proposed. However, special woven friction materials made using these glass fibers and Motomura containing glass fibers have a higher friction coefficient and poor judder and wear characteristics compared to conventional asbestos-based friction materials. There were drawbacks.
As a result of intensive studies to improve these problems, the present inventors have found that judder can be achieved by using a friction material base material in which a friction modifier is attached or dispersed in a string containing bulky yarn using at least continuous glass fibers. It was discovered that a friction material with excellent characteristics, wear characteristics, and rotational fracture strength could be obtained, and the present invention was developed.

いて著しく好ましい。As the bulking method, any known method can be employed and there are no particular limitations. The mixed string-like material may be mixed during bulk processing or may be mixed in a subsequent process such as twisting, but the former is preferable from the viewpoint of uniformity. The types of glass fiber are E glass,
A glass, C glass, S glass, G glass, etc. are used, and there are no particular limitations. Further, other fibers that can be used together with glass fibers include organic fibers, inorganic fibers other than glass fibers, and metal wires are also included if necessary. As organic fibers, cotton, cotton, aromatic polyamide, imide fibers, quinol fibers, etc. can be used, and as inorganic fibers other than glass fibers, carbon fibers, ceramic fibers, etc. can be used. Further, metal wires are sometimes used for anti-rust measures, and masu wire, zinc wire, wire, aluminum wire, etc. can be used. Friction modifiers used in the present invention include cashew dust, carbon powder, barium sulfate, calcium carbonate, diatomite, metal oxides (iron oxide, lead oxide, chromium oxide), metal sulfides (lead oxide, molybdenum sulfide). ) and the like can be used, but the use of cashew dust, carbon powder, and barium sulfide is particularly preferable in terms of their effectiveness.

The proportion of the friction modifier dispersed in the string is preferably in the range of 3 to 50% by weight, more preferably in the range of 5 to 3% by weight. If the friction adjustment ratio is less than 3% by weight, the objective of the present invention, which is to improve judder characteristics and wear resistance, will be insufficient. In addition, if it exceeds 5% by weight, the mechanical strength such as rotational breaking strength will be low and the friction modifier will drop off from the base material. A range of 3 to 5% by weight based on the material is appropriate. The means for attaching or dispersing the friction modifier to the string containing the bulky textured yarn is as follows:
In the case of powder, etc., the friction modifier can be incorporated into the fibers by a sprinkling method, a fluidizing method, etc., or it can be mixed with a suitable binder and infiltrated and fixed into the string.

キラィニング等の摩擦材についても同様の効果が得られ
る。As a result of the test, it was confirmed that there were clear differences between the comparative example and each example in terms of friction coefficient, wear amount, and judder resistance. Although the present invention has been described for the case where it is applied to clutch fittings, similar effects can be obtained with friction materials such as disc pads and brake linings.
