Abstract: A sound absorbing material having a homogenous mixture of an organic man-made fiber, an inorganic man-made fiber, a co-binder, and a cellulose material wherein the organic man-made fiber is polyester, the inorganic man-made fiber is fiberglass, and the co-binder is a thermo-setting resin. The cellulose material may include Kaolin clay and/or boric acid.
Abstract: A treated backing comprises a fabric and a composition that comprises epoxy resin preparable by reaction of epichlorohydrin with at least one of bisphenol A or bisphenol F, polyfunctional (meth)acrylate, dicyandiamide, and photoinitiator.
Abstract: A friction material has a first layer of a base material and a second layer of at least one type of friction modifying particle having substantially symmetrical geometric shapes on a top surface of the base material. The second layer has an average thickness of about 30 to about 200 microns and the surface area coverage of about 80 to about 100% such that the top layer has a fluid permeability lower than the first layer.

Abstract: A method of producing a lightweight heat resistant and insulative composite sheet, and containing glass fibers, consisting essentially of homogenized glass fiber and binder materials forming a first layer, binder material extending in a second layer on a surface of the first layer and bonded thereto, woven glass fiber facing cloth extending in a third layer on a surface of the second layer and bonded thereto so that the second layer is sandwiched between the first and third layers, binder material in all layers being cured, to integrate the layers.
Abstract: An article containing: a substrate having at least two surfaces; and raised elements on at least one surface of the substrate, wherein the article is useful for providing skin care benefits is disclosed. The raised elements may be made from hot melt coatings, natural rubber, synthetic rubber, polyolefins, ethylene vinyl acetate, or thermoplastic elastomers.
Abstract: The present invention relates to a fibrous base material for use in a non-asbestos, non-metallic friction material comprising less fibrillated aramid fibers, carbon particles, cotton fibers, carbon fibers and at least one filler material, and the non-asbestos, non-metallic friction material produced therefrom. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-base resin material, including, for example, a mixture of a phenolic resin and a silicone resin.
Abstract: A wet paper friction material, mainly used for a slip lock-up of an automatic transmission, obtained by impregnating a paper material with a thermosetting resin, thermosetting, and molding under pressure, to attain compatibility between a good frictional characteristic and good fatigue strength under compression, wherein the paper material, in addition to a cellulose pulp and a filler, contains 30 to 80 wt % of aramid pulp with its drainability being adjusted to 250 to 440 ml in a total amount of pulp, and further contains, as a friction modifier, diatomaceous earth cylindrically formed so as to be net-like in the cylinder part and having its mean length 4 to 6 .mu.m.
