Abstract
A brake lining, especially for vehicle drum brakes. The material of the brake lining includes a base in which are embedded oriented reinforcing fibers having a modulus of elasticity larger by at least one order of magnitude than the modulus of elasticity of the material of the brake lining. According to their lengths, at least 60% of the reinforcing fibers in the projection falling onto the plane normal to the axis of rotation enclose an angle alpha in the range between 20.degree. and 70.degree. with the normal of the frictional surface and more than 50% falling onto one side of the normal enclose an angle of 90.degree. minus alpha with the frictional motion vector.
