The fiber reinforced composites have come of age as economically and structurally available materials. It is well known that these have some basic features different from iron materials, such as a considerable scatter of mechanical properties and pronounced rigidity reduction under repeated stress. It this work, in order to investigate these characteristic fatigue behaviors, the number of cycles to failure, the reduction of rigidity and the residual strength are examined in three kinds of the commercial fiber reinforced composites under pulsating tensile stress. The fatigue damage in the proposed unit model having the properties peculiar to composite laminate is computed by using the linear elastic fracture mechanics and the calculated results agree with the experimental data fairly well.
