An abrasive article has an abrasive portion and chopped strand fibers (CSF) with enhanced strength and/or fracture of toughness. The CSF may be coated with a thermoplastic having a loss on ignition of at least about 2 wt %. The CSF can have a primary coating and a secondary coating on the primary coating. At least some of the CSF can have a length of at least about 6.3 mm.

Abrasive article reinforced by discontinuous fibers

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 &#x3bc;m. 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.
