Abstract
A clutch facing material including strings of asbestos to which are applied a mixture of cashew dust resin and graphite which is in turn mixed with cashew dust. The graphite is inseparably contained in the mixture of cashew dust resin and graphite and, in combination with the cashew dust, provides a clutch facing material showing a high frictional coefficient even at high temperatures.
Claims8
A clutch facing comprising strings of asbestos having a material applied thereto, said material comprising a first additive consisting essentially of a mixture of solid cashew resin and graphite, and a second additive comprising cashew dust.
A clutch facing material comprising strings of asbestos having a mixture of materials applied thereto, said mixture comprising a first additive of graphite contained in a cashew dust resin, said graphite being inseparably contained in said first additive, said mixture further containing a second additive comprising cashew dust, said graphite being from 5-100 parts by weight per 100 parts of said cashew dust resin, and said cashew dust being present in from 50-300 parts by weight to 100 parts of said first additive.
A method for manufacturing a clutch facing material comprising the steps of:
- (a) mixing powdered graphite with liquid cashew resin to form a first mixture;
- (b) solidifying said resin, thereby solidifying said first mixture;
- (c) crushing said solidified first mixture to form a powder;
- (d) mixing said powder with cashew dust to form a second mixture;
- and
- (e) applying said second mixture to asbestos strings.
A method of making a clutch facing material comprising the steps of:
- (a) forming a powder of solidified cashew resin;
- (b) mixing said powder with graphite to form a first mixture;
- (c) mixing said first mixture with cashew dust to form a second mixture;
- and
- (d) applying said second mixture to asbestos strings.
