摘要： To be able to promote discharge of lubricating oil in a disengaged state while maintaining a large lining area to such an extent that it does not affect torque transmission capacity, heat resistance, and peeling resistance thereby to obtain an excellent effect to reduce a drag torque in a wide range of relative rotation speeds.In a segment friction material 1A as a wet friction material, drag torque reducing grooves 5A are provided only on top surfaces of part of segment pieces 3A among thirty pieces of segment pieces 3, 3A. A series of drag torque reducing grooves 5A extend over five segment pieces 3A along a direction almost at right angles to a straight line connecting a center point 5Aa thereof and a center O of a circumference. The series of drag torque reducing grooves 5A are provided at three places on the circumference. Thereby, discharge of ATF is promoted without reducing a lining area and an oil film is formed on the top surface of the segment piece 3A. Thus, a great effect to reduce a drag torque was obtained in a wide range of relative rotation speeds (500 rpm to 5000 rpm).

摘要： 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.

摘要： In a wet friction material, inorganic filler of small particle size is added to fill clearances or space between fibers with the inorganic filler. The inorganic filler is attached to the fibers with each other to reinforce strength of the wet friction material when an impregnated resin is hardened. Absolute specific gravity of the inorganic filler is set at a fixed value so as to make its compounding quantity small, thereby assuring a pore diameter of a friction material substrate without filling pores of the friction material substrate with the inorganic filler.

摘要： In a wet friction material, to be able to reduce a drag torque, while being greater in a disengagement feature and a positive μ-V slope characteristic by keeping a pore diameter large without generating strength reduction or increase in settling quantity.By adding small-particle inorganic filler 2, it attaches the inorganic filler 2 to inter-fiber 3 and it can obtain an effect to improve strength of friction material substrates 1 by connecting the inter-fiber 3 when an impregnated resin is hardened. Moreover, by keeping an absolute specific gravity of the inorganic filler 2, its compounded capacity becomes small and it can secure a pore diameter 5 of the friction material substrates 1 without being filled in pores of the friction material substrates 1 with the inorganic filler 2. As a result, it makes faster to absorb ATF from a friction surface. Therefore, it improves the disengagement feature and the positive μ-V slope characteristic, while reducing the drag torque.
