The present invention is to provide a friction material composition comprising a fibrous material except for asbestos, an inorganic friction regulating agent, an organic friction regulating agent and a binder, wherein active alumina is contained as the inorganic friction regulating agent, and a fluorine series polymer is contained as the organic friction regulating agent, and to provide a friction material using the friction material composition.

Friction material composition and friction material therefrom

There are disclosed a friction material composition which comprises a fibrous material except for asbestos, an inorganic friction regulator, an organic friction regulator and a binder, part of the inorganic friction regulator is &#x3b1; alumina and &#x3b3; alumina in combination, a weight ratio of the &#x3b1; alumina and the &#x3b3; alumina, &#x3b1; alumina:&#x3b3; alumina, is in the range of 1:20 to 1:5, and part or whole part of the binder is a silicon-containing phenol resin, and a friction material obtained by molding the friction material composition under heating and pressure.

Friction material composition and friction material using the same

A disc brake pad obtained by using a composition comprising a fibrous base material except for asbestos, a binder and a friction adjusting agent, wherein a silicone modified resin is contained as a part or whole of the binder and zeolite is contained as a part of the friction adjusting agent can prevent a transfer film from contacting with water or remove the water once adsorbed in the transfer film and can lower the sound pressure of creep groan.

A catalyst selected from a perfluorosulfonic acid and an anhydride thereof enables a non-conjugated drying oil to react with a phenol to form a phenol-added vegetable oil without causing hydrolysis of the non-conjugated drying oil. The phenol-added vegetable oil is allowed to react with an aldehyde to form a vegetable oil-modified phenolic resin. A laminate produced by impregnating paper with the vegetable oil-modified phenolic resin and laminating and molding the impregnated paper is excellent in low temperature punching quality and electrical properties and is free from low molecular weight components oozing out the surface of the laminate.

Method of preparing vegetable oil-modified phenolic resin and laminate

A clutch driven plate comprising a clutch facing plate molded from a clutch facing material comprising a fiber, a binder, and a friction modifier and a back-up plate carrying the clutch facing plate, wherein a number of dimples are formed on the surface of the clutch facing plate. The clutch driven plate is obtainable by thermo-compression molding a back-up plate and a clutch facing material comprising a fiber, a binder, and a friction modifier to integrate the plate and clutch facing material into one body.

A clutch driven plate comprising a clutch facing plate molded from a clutch facing material comprising a fiber, a binder, and a friction modifier and a back-up plate carrying the clutch facing plate, wherein a number of dimples are formed on the surface of the clutch facing plate. The clutch driven plate is obtainable by thermo-compression molding a back-up plate and a clutch facing material comprising a fiber, a binder, and a friction modifier to integrate them in one body.

Ceramic coated laminates for printed circuit boards produced by flame spraying a ceramic powder on a metal plate such as copper foil or a woven fabric prepreg, laminating one or two ceramic coated metal plates and woven fabric prepregs so as to place the ceramic layer between the metal plate and the prepreg, hot-pressing the laminated members, and if necessary peeling off the metal plate(s), are excellent in thermal conductivity and heat resistance.

Ceramic coated laminate and process for producing the same

The present invention is directed to a hollow frame for a game racket substantially constructed from a first fiber reinforced thermoplastic frame member which continuously provides outside peripheral portions of the tadpole shape of the frame including a head portion, a straight handle portion and a triangular throat portion which connects the head and handle portions, and a second fiber reinforced thermoplastic frame member which integrally provides the inside remaining portions, as viewed in the tadpole plan view, of the head, throat and handle portion, wherein the first and second frame members are joined together so as to form a hollow frame.

A carbon filament wound hollow cylinder comprising at least two carbon filament layers, an inner axial direction-wound layer and an outer circumferential direction-wound layer, characterized in that the modulus of longitudinal elasticity in the circumferential direction of the inner layer is lower than that of the outer layer. Such a cylinder is capable of preventing possible crack formation after shaping owing to its much reduced residual stress exerted due to thermal expansion of a mandrel during shaping and capable of being stably employable as a rotary drum for, ultracentrifugation because compressive stress is exerted effectively to cancel tensile stress caused by thermal stress for causing interlaminer delamination during high speed rotation.
