Abrasive article having a core including a composite material

Abstract

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.

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 an organic material and a metallic material, and wherein the core comprises a flexural strength of at least 60 MPa and a dampening factor of at least 0.007. 
     
     
         2 . The abrasive article of  claim 1 , wherein the composite material includes at least a first filler. 
     
     
         3 . The abrasive article of  claim 1 , wherein the core is essentially free of a glass material. 
     
     
         4 . The abrasive article of  claim 1 , wherein the core is essentially free of glass fibers. 
     
     
         5 . The abrasive article of  claim 1 , wherein the organic material comprises a polymer. 
     
     
         6 . The abrasive article of  claim 1 , wherein the organic material comprises a resin. 
     
     
         7 . The abrasive article of  claim 1 , wherein the organic material comprises phenolic resin. 
     
     
         8 . The abrasive article of  claim 1 , wherein the organic material consists essentially of phenolic resin. 
     
     
         9 . The abrasive article of  claim 1 , wherein the core includes a majority content of the composite material. 
     
     
         10 . The abrasive article of  claim 1 , wherein the core comprises at least 60 wt % of the composite material for a total weight of the core. 
     
     
         11 . The abrasive article of  claim 1 , wherein the core consists essentially of the composite material. 
     
     
         12 . The abrasive article of  claim 1 , wherein the core comprises a first portion including the composite material and a second portion having a second material different than the composite material. 
     
     
         13 . The abrasive article of  claim 1 , wherein the first portion and second portion are different in at least one parameter selected from the group consisting of size, shape, volume, radial position with respect to each other within the core, axial position with respect to each other within the core, or a combination thereof. 
     
     
         14 . The abrasive article of  claim 1 , wherein the composite material includes a content of the organic material (Com) within a range of at least about 5 wt % and not greater than 50 wt % for the total weight of the composite material. 
     
     
         15 . The abrasive article of  claim 1 , wherein the composite material includes a content of the organic material (Com) within a range of at least about 15 vol % and not greater than 60 vol % for the total weight of the composite material. 
     
     
         16 . The abrasive article of  claim 1 , wherein the metallic material comprises a metal or metal alloy. 
     
     
         17 . The abrasive article of  claim 1 , wherein the metallic material comprises a metal selected from the group consisting of Al, Ga, Ge, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ag, Ta, W, Ot, Au, Sn, Sb, or a combination thereof. 
     
     
         18 . The abrasive article of  claim 1 , wherein the metallic material has a density within a range of at least 1 g/cm 3  and not greater than 12 g/cm 3 . 
     
     
         19 . The abrasive article of  claim 1 , wherein the metallic material consists essentially of metal. 
     
     
         20 . The abrasive article of  claim 1 , wherein the metallic material comprises aluminum.
