Microfiber reinforcement for abrasive tools

An abrasive article, comprising:

• an organic bond material including one of a thermosetting resin, a thermoplastic resin, or a rubber;
• an abrasive material, dispersed in the organic bond material;
• and
• a plurality of microfibers, uniformly dispersed in the organic bond material, wherein the microfibers are individual filaments having an average length of less than about 1000 μm and a diameter less than about 10 microns;
• wherein the abrasive article includes from 10% by volume to 50% by volume of the organic bond material, from 30% by volume to 65% by volume of the abrasive material, and from 1% by volume to 20% by volume of the microfibers.

A method of abrasive processing a workpiece, the method comprising:

• mounting the workpiece onto a machine capable of facilitating abrasive processing;
• operatively coupling an abrasive article to the machine, the abrasive article comprising
• an organic bond material;
• an abrasive material, dispersed in the organic bond material;
• and
• a plurality of microfibers, uniformly dispersed in the organic bond material, wherein the microfibers are individual filaments having an average length of less than about 1000 μm;
• and
• contacting the abrasive article to a surface of the workpiece.
