In this study, the wear characteristics of CFRP under the three-body conditions were investigated using a vibratory environment. An abrasive wear apparatus was operated based on the pin-on-plate method at the piston-reciprocated sliding friction. The vibrating action was induced by mean of a mechanical oscillator. The velocity ratio was defined as the ratio of the maximum vibratory velocity (aw) of the test piece to the sliding velocity X) of the plate. The amplitude (a) and the velocity ratio (aw/X) were varied to examine the influence of the vibrating action on the abrasive wear characteristics of CFRP. The experimental results are summarized as follows. (1) The wear rate of the high modulus type CFRP is greater than that of the high-strength-type. (2) In the abrasive wear of CFRP, no effect of fiber reinforcement is observed in the three-body abrasive wear. (3) In the vibration action in which the overlapping distance is 0.3 mm or less, the wear rate is independent on the vibration. However, when the overlapping distance is more than 0.3 mm, the wear rate becomes dependent upon the vibration.
