Claims
- 1. A sliding member comprising a mixture of fluorine resin and carbon fibers treated with a fluorine-containing silane modifying agent represented by the formula R.sup.1 -SiX.sub.3 wherein R.sup.1 represents an alkyl group having from 1 to 10 carbon atoms, a part or the whole of the hydrogen atoms of which are replaced with fluorine atoms and X represents a hydrolyzable group or a chlorine atom, wherein the carbon fibers have a diameter of from 1 to 20 .mu.m and an aspect ratio of from 1:1 to 50:1, and wherein the amount of the carbon fibers is from 1 to 30 parts by weight per 100 parts by weight of the fluorine resin.
- 2. A sliding member as claimed in claim 1, wherein the fluorine resin is at least one member selected from the group consisting of a polytetrafluoroethylene, a tetrafluoroethylene/hexafluoropropylene copolymer, a tetrafluoroethylene/perfluoroalkylvinyl ether copolymer, a polychlorotrifluoroethylene, and an ethylene/tetrafluoroethylene copolymer.
- 3. A sliding member as claimed in claim 1, wherein the carbon fibers have a diameter of from 3 to 15 .mu.m.
- 4. A sliding member as claimed in claim 1, wherein the carbon fibers have an aspect ratio of from 3:1 to 40:1.
- 5. A sliding member as claimed in claim 1, wherein the fluorine-containing silane modifying agent is selected from the group consisting of trifluoropropyltrimethoxysilane, trifluoropropyltriethoxysilane, trifluoropropyltri(.beta.-methoxyethoxy)silane, 2-perfluorohexylethyltrimethoxysilane, 2-perfluorooctylethyltriethoxysilane and 2-perfluorooctylethyldimethoxymethylsilane.
- 6. A sliding member as claimed in claim 1, wherein the hydrolyzable group is an alkoxy group having 1 to 4 carbon atoms.
- 7. A sliding member as claimed in claim 1, wherein the amount of the carbon fibers is from 3 to 20 parts by weight per 100 parts by weight of the fluorine resin.
- 8. A composition for producing a sliding member, said composition comprising a fluorine resin and carbon fibers treated with a fluorine-containing silane modifying agent represented by the formula R.sup.1 -SiX.sub.3 wherein R.sup.1 represents an alkyl group having from 1 to 10 carbon atoms, a part or the whole of the hydrogen atoms of which are replaced with fluorine atoms and X represents a hydrolyzable group or a chlorine atom, wherein the carbon fibers have a diameter of from 1 to 20 .mu.m and an aspect ratio of from 1:1 to 50:1, and wherein the amount of the carbon fibers is from 1 to 30 parts by weight per 100 parts by weight of the fluorine resin.
- 9. A sliding member as claimed in claim 1, further comprising a lubricant.
