Claims
- 1. A method of forming a clutch component, comprising the steps of:
- a) choosing a polymer-derived ceramic resin is from silicon-carboxyl resin, or alumina silicate resin;
- b) choosing fibers comprising at least one of alumina, Nextel 312, Nextel 440, Nextel 510, Nextel 550, silicon nitride, silicon carbide, HPZ, graphite, carbon, and peat;
- c) coating said fibers with an interface material comprising at least one 0.1-5.0 micron thick layer of at least one of carbon, silicon nitride, silicon carbide, and boron nitride;
- d) choosing an erosion-resistant/friction-inducing material comprising at least one of alumina, mullite, silica, silicon carbide, titania, silicon nitride, and boron nitride;
- e) combining said erosion-resistant/friction-inducing material, coated fibers and resin;
- f) forming the clutch component from the combined erosion-resistant/friction-inducing material, coated fibers and resin; and
- g) curing the resin to form a ceramic.
- 2. The method of claim 1 wherein:
- the erosion-resistant/friction-friction inducing material is disposed throughout said clutch component.
- 3. The method of claim 2 wherein:
- the erosion-resistant/friction-friction inducing material is only adjacent to said friction surfaces.
- 4. A method of forming a clutch friction pad, comprising the steps of:
- a) choosing a polymer-derived ceramic resin is from silicon-carboxyl resin, or alumina silicate resin;
- b) choosing fibers comprising at least one of alumina, Nextel 312, Nextel 440, Nextel 510, Nextel 550, silicon nitride, silicon carbide, HPZ, graphite, carbon, and peat;
- c) coating said fibers with an interface material comprising at least one 0.1-5.0 micron thick layer of at least one of carbon, silicon nitride, silicon carbide, and boron nitride;
- d) choosing an erosion-resistant/friction-inducing material comprising at least one of alumina, mullite, silica, silicon carbide, titania, silicon nitride, and boron nitride;
- e) combining said erosion-resistant/friction-inducing material, coated fibers and resin;
- f) forming the clutch friction pad from the combined erosion-resistant/friction-inducing material, coated fibers and resin; and
- g) curing the resin to form a ceramic.
- 5. A method of forming a clutch friction pad and attaching it to a clutch part comprising the steps of:
- a) forming a clutch friction pad of a structural fiber reinforced ceramic matrix composite material comprising fibers coated with an interface material to impart wear-resistance to the component, a polymer-derived resin in its ceramic form, and an erosion-resistant/friction-inducing material disposed within the polymer-derived ceramic resin; said friction pad having attaching members extending therefrom;
- b) placing the clutch friction pad in a mold for a metal clutch part with the attaching members extending into a portion of the mold to be filled with metal forming the clutch part; and,
- c) filling the mold with metal to form the clutch part and capture the attaching members therein.
