    Abstract: Electrically conductive articles are provided, including a composite including (a) a resin, and (b) electrically conductive shaped particles distributed in the resin, the particles having a monosized distribution. Each particle has a shape including at least a first surface and a second surface intersecting the first surface at an angle a between about 5 degrees and about 150 degrees. The composite has a thickness and often each of the electrically conductive shaped particles distributed in the resin is oriented within the resin such that the particle does not extend beyond the thickness of the composite. A method for making an electrically conductive article is also provided, including (a) providing electrically conductive shaped particles having a monosized distribution, and (b) distributing the particles into a resin to form a composite.

    Abstract: In various embodiments, the present invention provides a structured abrasive article. The structured abrasive article includes an abrasive layer disposed on a backing. The abrasive layer includes shaped abrasive composites, which include abrasive particles dispersed in a polymeric binder. Each of the shaped abrasive composites independently includes a contoured base, which includes a first end disposed on the backing, a second end, and a plurality of sidewalls connecting the first end and the second end. A plurality of walls extends away from the contoured base. The abrasive article additionally includes a grinding surface, which includes a plurality of cusps and a plurality of facets that contact a recessed feature capable of being contained within a geometric plane. A portion of the recessed feature is disposed closer to the contoured base than is each of the cusps, and each cusp is formed by an intersection of two of the walls and a facet.

    Abstract: Structured abrasive articles include a backing and shaped abrasive composites secured to the backing. The shaped abrasive composites include abrasive grits dispersed in a binder matrix. The shaped abrasive composites include a bottom surface and a top surface opposite and not contacting the bottom surface, and at least three sidewalls abutting both the bottom and top surfaces and two other sidewalls. In one embodiment, at least two cusps are formed by the top surface and individual sidewalls. In another embodiment, the top surface includes at least two triangular facets that contact at least two respective sidewalls and at least two cusps. The top surface includes at least one interior recessed portion nearer the cusps than the bottom surface. Methods of abrading a workpiece using the structured abrasive article are also disclosed.
