    Abstract: A method of manufacturing a structure includes: a molding step of impregnating carbon fibers with a resin material and curing the resin material for molding a carbon fiber composite material; a polishing step of polishing a polishing region on a surface of the carbon fiber composite material molded in the molding step, with an abrasive that has a predetermined hardness; and a bonding step of bonding, through an adhesive, another member to a part of the polishing region polished by the polishing step. The molding step forms, in a top layer, a polishing layer that has a hardness which is lower than the predetermined hardness, and forms a surface protective layer that is lower than the polishing layer, protects the carbon fiber composite material from the abrasive, and contains a protective filler having a hardness which is higher than the predetermined hardness.

  • Patent number: 10280687
    Abstract: Embodiments relate to polycrystalline diamond compacts and methods of manufacturing such compacts in which an at least partially leached polycrystalline diamond (“PCD”) table is infiltrated with first and second infiltrants. The first infiltrant includes a low viscosity cobalt-based and/or nickel-based alloy infiltrant. The second infiltrant (e.g., copper) is specifically selected to be more easily infiltrated and/or removed (e.g., leached) than a pure cobalt infiltrant. In an embodiment, a method includes forming a PCD table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table may be at least partially leached to remove at least a portion of the metal-solvent catalyst therefrom. The leached PCD table and a substrate are subjected to a second HPHT process effective to bond the substrate to the leached PCD table while at least partially infiltrating the PCD table with at least the first and second infiltrants.

  • Patent number: 10196314
    Abstract: Multi-step milling processes to prepare cBN composite powder forms a first powder mixture by adding a binder and a first cBN component, mills the first powder mixture for a first time period, combines a second cBN component with the milled first powder mixture to form a second powder mixture, and mills the second powder mixture for a second time period (less than the first time period) to form the cBN composite powder. A ratio of the D50 value of the second cBN component to the D50 value of the first cBN component is at least 3.0. Two-step milling with different milling times for the two cBN component fractions controls the amount of mill debris in the cBN composite powder mixture. Further processing of the cBN composite powder under HPHT conditions forms a cBN-based ceramic with an average value of a cBN particle free diameter of less than 2.0 microns.
