Abstract
Official abstract text for this publication.
An abrasive article including a bonded abrasive body coupled to a core, the core includes a composite material including an organic material and a metallic material, and the composite material includes at least a first filler that can include nitrides, carbides, borides, oxides, silicates, or a combination thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. An abrasive article comprising: a bonded abrasive body coupled to a core, wherein the core comprises a composite material including a mixture of an organic material, a metallic material, and a first filler, wherein the composite material includes a content of the metallic material (Cmm) and a content of the organic material (Com), wherein the composite material comprises a weight percent ratio Cmm/Com of at least 1, wherein the composite material comprises at least 45 wt. % of the metallic material, wherein the metallic material comprises a metal selected from the group consisting of Al, Ge, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ag, Ta, W, Ot, Au, Sn, Sb, or a combination thereof, and wherein the first filler is selected from the group consisting of nitrides, carbides, borides, oxides, silicates, or a combination thereof. 2. The abrasive article of claim 1 , wherein the first filler includes a polycrystalline material. 3. The abrasive article of claim 1 , wherein the first filler consists essentially of a polycrystalline material. 4. The abrasive article of claim 1 , wherein the first filler comprises a material selected from the group consisting of a silicate, a carbide, or a combination thereof. 5. The abrasive article of claim 1 , wherein the first filler comprises wollastonite. 6. The abrasive article of claim 1 , wherein the first filler consists essentially of wollastonite. 7. The abrasive article of claim 1 , wherein the first filler comprises silicon carbide. 8. The abrasive article of claim 1 , wherein the first filler is present in a first content (Cff), and the core comprises a minority content of the first content for a total weight of the core. 9. The abrasive article of claim 1 , wherein the core comprises a first content within a range of at least 1 wt % and not greater than 30 wt %. 10. The abrasive article of claim 1 , wherein the organic material comprises a polymer. 11. The abrasive article of claim 1 , wherein the organic material comprises phenolic resin. 12. The abrasive article of claim 1 , wherein the core includes at least 60 wt % of the composite material for a total weight of the core. 13. The abrasive article of claim 1 , wherein the abrasive body comprises a dampening factor of at least 0.007.
