EVALUATION OF CYCLIC DAMAGE IN CARBON FIBER REINFORCED PLASTICS

摘要

The progressive nature of fatigue damage due to cyclic loading on carbon (graphite) fiber reinforced plastics (CFRP) was analyzed. After cycling approximately to the 10~7 number of cycles, the specimens were released from the material testing system (MTS) machine to prevent any additional damage. The residual strength of the specimens subjected to fluctuating tension with a given number of cycles was then measured.
