This paper deals with the fatigue strength the paper-based friction materials under cyclic shear-compressive loading which is regarded as a real loading condition in an automotive automatic transmission. The influence of ratios between the shear and compressive stress on the fatigue strength was examined. The fatigue strength decreases with increasing number of cycles. The static fracture strength and fatigue limit is high under the dominant compressive stress condition. The amount of deformation of the paper-based friction materials does not change with the compressive stress under the compressive loading, while the Young's moduli increase with increasing compressive stress.
