Abstract: The present disclosure provides a thermally conductive article including a pad having first and second opposed major surfaces and a thickness therebetween. The thickness is formed of entangled thermally conductive fibers and at least a portion of the entangled thermally conductive fibers have at least one terminal end at the first opposed major surface, the opposed second major surface, or both. The pad is at least partially impregnated with a polymer. Another thermally conductive article is provided including a) a pad having first and second opposed major surfaces and a thickness therebetween; b) a first thermally conductive skin layer; and c) a second thermally conductive skin layer. The thickness of the pad is formed of aligned thermally conductive fibers, and at least a portion of the thermally conductive fibers have a terminal end at the first opposed major surface and the opposed second major surface.

Abstract: Provided is an abrasive article comprising (a) a metallic foil having a first and second surfaces and voids therebetween, (b) a plurality of abrasive particles substantially in the voids, and (c) an alloy at least partially between the abrasive particles and the foil in the voids, wherein the alloy comprises a second component and a portion of the metallic foil near the voids. Also provided are methods of making and using such abrasive articles.

Abstract: A cylindrical, abrasive grinding wheel having a cylindrical abrasive region with an abrasive surface at an outer circular band thereof. The abrasive region includes layers of abrasive particles. The layers of abrasive particles can be tilted with respect to an axis of rotation of the grinding wheel or they can such that grooving in the grinding wheel and a workpiece ground by the grinding wheel can be reduced. Alternatively, the abrasive region can be formed from a plurality of abrasive segments each having layers of abrasive particles. The layers of abrasive particles can be staggered in the direction of the axis of rotation from one segment to another. This can also reduce grooving in the grinding wheel and workpieces.

Abstract: A tool including abrasive segments, which can be superabrasive segment, mounted to a mounting plate and a method for making the same. The abrasive segments include hard particles and are formed by sintering layers of hard particles with layers of bond material to form a laminated sheet. The abrasive segments are then cut from the laminated sheet and mounted to a planar face of the mounting plate to form a portion of a working region of the tool. Each segment has a grinding surface which can be formed perpendicular to the layers of bond material and layers of hard particles so that the concentration of hard particles at the grinding surface is relatively high. This allows the portion of working surface made up of the abrasive segments to relatively small. The segments can also be mounted to the substrate disc such that the grinding surface of each segment is at an angle to the planar face.

Abstract: An abrasive surface for cutting and grinding tools and having abrasive particles embedded in a filler material. The abrasive surface is bonded to the perimeter edge of a rigid hub and has a circumferential dimension and a width dimension. The abrasive surface is divided along both the circumferential dimension and the width dimension into a plurality of hard regions and soft regions. The hard regions wear more slowly that the soft regions and so different patterns of hard regions and soft regions produce different cutting profiles. A method for fabricating the abrasive surface includes forming a laminated sheet from a plurality of laminated layers. Each laminated layer includes at least a layer of soft, easily deformable material and a layer of abrasive particles. The layers of abrasive particles can be formed into staggered rows to form the pattern of hard regions and soft regions. The layers of the laminated layers are sintered together to form the laminated sheet from which the abrasive surface is cut.

Abstract: A coatable, thermally curable binder precursor solution, the solution including a 30-95% solids solution of a thermally curable resin and a reactive diluent. The reactive diluent may be selected form urea derivatives, alkylsubstituted 2-aminoalcohols, .beta.-ketoalkylamides, nitro alkanes, and poly(oxyalkylene) compounds, and has at least one functional group independently reactive with methylol groups of the resin and with aldehydes. The thermally curable resin may include up to 50% (wt of total resin) of an ethylenically unsaturated monomer. Method of making abrasive articles are also presented.

Abstract: A rotatable wheel for removing material from a workpiece has a rigid circumferential surface on which a removable abrasive strip is mounted. The circumferential surface has a transverse slot extending into a cavity within the wheel which is generally covered by a coverplate secured over the cavity. Within the cavity is a first device for engaging the leading end of the strip and a second device for engaging the trailing end of the strip. The first device includes a positioner which is operable to align the first device under an opening in the coverplate to permit insertion or removal of the leading end of the strip. Similarly, the second device includes a locator arm which is operable to align the second device under an opening in the coverplate to permit insertion or removal of the trailing end of the strip. The first device places static tension on the strip, while the second device places dynamic tension on the strip as the wheel is rotated.
