    Abstract: Composite material with two or a plurality of layers with a coating layer (5) which is applied directly on the rough surface (2) of a substrate and which comprises a lake base of polyimid and at least one finely spread additive in said base. Upon forming the coating layer (5) as a friction or sliding layer, such layer may contain about 99 to 60% by volume, preferably 90 to 80% by volume of thermo-setting polyimid lake and about 1 to 40% by volume, preferably 10 to 20% by volume of self-lubrication additives, particularly low molecular weight PTFE, with a grain size comprised between 5 and 7 (Alpha). For manufacturing said composite material, the powder additive is intimately mixed with the polyimid lake and homogenized until it becomes slightly viscous or pasty, deposited on the metal substrate and fixed thereto by sintering.
