Abstract: Methods of making abrasive articles involve adhering shaped abrasive particles to a reinforcing member according to a predetermined pattern and optionally orientation, and depositing a space-filling binder precursor on the reinforcing member and shaped abrasive particles to provide a filled abrasive preform, disposing another reinforcing member onto the filled abrasive preform, and curing the abrasive article precursor to form the abrasive articles. In some aspects, multiple abrasive preforms are stacked on each other. Bonded abrasive wheels preparable according to the methods are also disclosed.
