Abstract
A composition that can be used for abrasive processing is disclosed. The composition includes 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. The microfibers are individual filaments having an average length of less than about 1000 μm. Abrasive articles made with the composition exhibit improved strength and impact resistance relative to non-reinforced abrasive tools, and improved wheel wear rate and G-ratio relative to conventional reinforced tools. Active fillers that interact with microfibers may be used to further abrasive process benefits.
