Abstract: The compositions of friction element for molding and the friction element for molding formed from the composition characterizing by addition of any one or more than two of the cermet powder (A) contained 75-50% of the mixed carbon and 25-50% of the alloy of stainless and iron series, the cermet powder (B) contained 75-50% of the mixed carbon and 25-50% of the alloy of tungsten and iron and/or the alloy of molybdenum and iron series or the cermet powder (E) of 75-50% of the mixed carbon and 25-50% of metal iron series, in range of 15-50%.

Abstract: Method for the production of friction linings, in which a mixture of fibers and wetting agents with water, in a fiber:water-mixture ratio from about 1:3 to 1:7, in the presence of plastifying components, is homogenized, the so formed plastic mass is shaped into a formed body, the formed body is dried, and then strengthened and hardened under heat and pressure. According to a variation, additives are first intensively mixed in after homogenization of the mixture containing fibers, wetting agent, plastifying component and water. The plastifying component may be a pectin, a polysaccharide, a vegetable glue or a viscose solution, in particular algin or gum arabic. Moreover, the plastifying component may be a colloid, in particular an aqueous colloid. It may also be a fiber colloid. In that case, it is preferred for the fiber colloid content to be greater than about 30% by weight.

Abstract: A brake system of a semi-metallic friction material and a braking component is characterized in that the friction material contains a metallic fiber and/or a metallic powder, a part or all of which has a lower hardness than that of the braking component.

Abstract: A semi-metallic friction pad subjected to rust preventive treatment, sides of which are applied with a heat-proof binder solution added with rust proof metallic powder therein. The rust proof metallic powder is single or mixed powder of stainless steel, aluminum or aluminum alloy, nickel or nickel alloy and chrome or chrome alloy. The heat-proof binder solution is a heat-proof resin solution of phenol resins, epoxy resins, melamine resins or silicon resins.

Abstract: Compositions useful as friction particles comprised of tri- and/or tetrafunctional phenol, difunctional phenol, aldehyde, a protective colloid, and a reaction promoting compound. The friction particles are formulated into friction elements. A process for producing the friction particles in particulate form.

Abstract: An improved process for molding fiber-reinforced articles and in particular, those articles which are formed from monofilaments such as metal fibers and processed mineral fibers of the slag type. The fiber-containing molding composition is enclosed in a restraining means, such as a bag, and placed in a mold and formed during which time the bag advantageously deteriorates.

Abstract: A friction material having an excellent heat-resistance, comprises 5 to 70% by weight of pulp-like particles consisting essentially of a heat-resistant aromatic polymeric material; 1 to 70% by weight of a fibrous material comprising at least one member selected from inorganic fibrous materials and heat-resistant organic fibrous materials; 1 to 35% by weight of a friction-regulating agent and; 5 to 40% by weight of a thermosetting polymeric resin.
