摘要： PROBLEM TO BE SOLVED: To provide a carbon composite material having a high, stable coefficient of friction even by a small number of times of braking, having low abrasion losses, and suitable for a brake material.
SOLUTION: A brake pad 10 is prepared by integrating a first layer 11 comprising a carbon fiber woven fabric 12 as a two dimensional carbon fiber material and a second layer 15 comprising a short carbon fiber material 16 by laminating, heating and pressurizing these layers. The first layer 11 is preferably formed by impregnating the carbon fiber woven fabric 12 with a liquid resin and then carbonizing the impregnated woven fabric. The second layer 15 is preferably formed by mixing a short carbon fiber material 16, a resin powder, a silica powder or a silicon powder and carbonizing the mixture. A phenol resin which is a thermosetting resin is used as the liquid resin and the resin powder. The first layer and the second layer is preferably formed together with a resin layer composed of a thermosetting resin and then carbonized for integration.

摘要： PROBLEM TO BE SOLVED: To provide a drum brake device which can reduce effectively occurrence of a breaking squeak. SOLUTION: A drum brake device 10 has a rim 18, to which a bonding agent 60 for adhering a brake lining 24 is applied at certain intervals. If a first brake shoe 16 vibrates in resonance to a braking squeak, a friction is generated between the rim 18 and lining 24 in the portions free of application of the bonding agent, and by this friction the vibratory energy is converted into thermal energy to cause reduction of the vibration. Because the bonding agent application area is made different about the boundary lying approximately in the center of the rim 18 which corresponds to the node of the secondary vibration as the chief vibration in resonance, the rate of vibratory-thermal conversion of the energy differs between one end and the other about approximate the center of the rim 18 as boundary. Therefore, the secondary vibration becomes irregular, and the braking squeak can be reduced effectively.

摘要： PROBLEM TO BE SOLVED: To obtain a friction material which comprises a filler component and a binder component contg. a fiber component and is excellent in stability of braking performance even when water is present on the surface, hardly causing an abnormal sound, by using, as at least a part of the fiber component, potassium titanate fibers which allow only a small amt. of potassium to dissolve out into 25 deg.C water. SOLUTION: Only potassium titanate fibers which allow potassium in an amt. of 0.1wt.% or lower (based on the total amt. of potassium titanate) to dissolve out into 25 deg.C water is used here. Conventional potassium titanate fibers allow about 1wt.% potassium to dissolve out, and when water is attached, potassium dissolves out into and reacts with water to form a film of hydrated titania, which adversely affects the stability of braking preformance. Potassium hexatitante or octatitanate fibers are used as the potassium titanate fibers. The binder component comprises the fiber component and a thermosetting resin (e.g. a phenol resin). Graphite, barium sulfate, etc., are used as the filler component.

摘要： PURPOSE:To improve the extent of abrasion resistance by manufacturing a disk brake rotor with cast iron made up of dispersing ZrSiO4 or the like to be mixed in a disk brake pad in an Fe-C structure. CONSTITUTION:Cast iron of Fe-3.3(wt.%)C is melted and cooled as being stirred up and it is kept somewhere about 1200 degrees. A globular grain of ZrSiO4 of 7 in Mohs' hardness and about 20mum in grain size just the same as those mixed in pad material is put in molten metal as much as about 3%wt. and, after being stirred up until it comes to uniformity, molded and thus a disk brake rotor consisting of such a material that has a structure made up of dispersing spheroidal graphite 2 and hard grains 3 in pearlite 1 is manufactured. Since the hard grains are dispersed in the cast iron of the rotor, abrasion resistance is improved.

摘要： PURPOSE:To prevent removal of a base material of steel fibers, improve abrasion resistance, and improve the strength of the pad in the title by using network or multi-branching steel fibers for the base material. CONSTITUTION:A net is manufactured of steel fibers 11 of material of SUM22 of diameter of about 60mu, this is cut to be a net chip of a rectangle of about 5X15mm to be used for a base material, and this is combined with other components in a predetermined composition to manufacture a disc brake pad. As a result, the steel fibers 11 give catches in the pad to make it difficult to pull them, and because the steel fibers 11 themselves have connecting force, it becomes more difficult to pull them, so removal of the base material is prevented. Abrasion resistance, which is of importance for a brake pad, can thus be improved, and the strength of the pad itself can also be improved.

摘要： PROBLEM TO BE SOLVED: To provide a friction material (a brake pad) reduced in occurrence of a squeak in the cold (at around -10°C, for example). SOLUTION: The friction material is produced by adding a binder, a lubricant, a friction adjusting material, a filler, and the like to a base material. In the friction adjusting material, cashew dust, which is subjected to heat treatment at around 500-1,100°C in an inert gas atmosphere, is added. In this way, a squeak rate in the cold is greatly lowered. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To allow a dry friction material to fully exhibit cutting action by hard particles on an opponent material even under severe conditions which provide a high temperature and a high surface pressure to a friction surface, so that a reduction in the coefficient of friction is suppressed.
SOLUTION: The dry friction material 10 comprises a resin binder 1 and a fibrous base material dispersed and held in the resin binder 1. At least part of the fibrous base material is composed of metal fibers 2 and hard particles 3 are dispersed and held on surfaces and in interior portions of the metal fibers 2. Even if the resin binder 1 is carbonized under severe conditions to form voids in the friction material, the metal fibers 2 are liable to be held near a friction surface of the dry friction material. The hard particles 3 dispersed and held on the surfaces and in the interior portions of the metal fibers 2 have high bonding force to the metal fibers 2 and drop hardly from the metal fibers 2.
