  • Patent number: 7972675
    Abstract: A friction material has a resin amount distribution that is the largest at a portion near a non-friction surface, that becomes lower toward an inside and that is the lowest at a portion near a friction surface. For example, such friction material is manufacture as follows. First, two friction materials are overlapped while the friction surfaces faced with each other. Then, the friction materials are dried at a room temperature. At this time, the resin has such a characteristic as to move while dragged by a solvent that dries from the non-friction surface located outside. Using such characteristic, the resin amount at the portion near the friction surface is lessened. Then, a temperature at the friction surface is made low and a temperature at the non-friction surface is made high in a drying step of the friction material. Thereby, the resin amount at the portion near the friction surface is lessened.

    Abstract: A nonwoven sheet material and method of construction thereof is provided. The nonwoven sheet material includes a heat bondable textile material and a used post consumer material. The used post consumer material includes at least one of a non-thermoplastic material, thermoplastic material, a plastic composition including different types of plastic constituents, and other materials containing contaminants such as dirt, oil, grease and the like in a non-washed state, which are ordinarily considered non-reusable waste. The used post consumer material is bonded with the heat bondable textile material to form the nonwoven sheet material and panels formed therefrom.

  • Patent number: 7897529
    Abstract: There is provided a substrate (1) capable of carrying uniformly dispersed, finely divided, particulate, solid particles, e.g., catalyst particles (10) and sustaining temperatures in excess of 1200 degrees F. The substrate comprises a top layer (2) for containing the particles (10) and composed of quartz fibers (4) with an average diameter of between about 0.1 and 4 microns and about 0 to 13% of microglass fibers having a softening point of about 1000 degrees F. A support layer (3) is composed of the fibers of the top layer and, in addition, bulk refractory, e.g., ceramic, fibers (6) having and average diameter of about 1 to 4 microns and 0 to 50% of chopped e-glass fiber (7). A method for producing the substrate is provided that includes wet laying the top and bottom layers in spaced apart times so that the juncture (8) between the two layers has intermingled fibers whereby the consolidated layers are not easily separated.

  • Publication number: 20110045223
    Abstract: A new method is disclosed for the exfoliation of hexagonal boron nitride into mono- and few-layered nanosheets (or nanoplatelets, nanomesh, nanoribbons). The method does not necessarily require high temperature or vacuum, but uses commercially available h-BN powders (or those derived from these materials, bulk crystals) and only requires wet chemical processing. The method is facile, cost efficient, and scalable. The resultant exfoliated h-BN is dispersible in an organic solvent or water thus amenable for solution processing for unique microelectronic or composite applications.
