    Abstract: A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating. The resulting product may be classified as a hybrid friction material, i.e., being a cross between semi-metallic and sintered full metallic friction materials.

    Abstract: A method for producing high density metal-containing lubricants and for comminuting metal into fine spherical particles is provided by heating a carrier fluid such as a lubricant, for example, and a metal until the metal becomes liquid, admixing the two components to form a homogeneous dispersion of metal globules in the carrier fluid, and then cooling the mixture. When a lubricant carrier fluid is used, the resulting high-density lubricant contains discrete, spherical metallic particles dispersed therein and higher density is achieved without any consequent loss of lubricating properties.
