Abstract
The present invention is a structured abrasive article including a substrate having a first major surface and a second major surface, and a plurality of shaped abrasive composites. Each of the shaped abrasive composites includes a bottom surface in contact with the first major surface of the substrate. Each of the bottom surfaces takes the shape of a concave polygon and each of the concave polygons has a convex hull having n sides.
