DELAMINATION OF CONTINUOUS CARBON FIBER REINFORCED POLY (PHENYLENE ETHER KETONE) UNDER MODE I CYCLIC LOADING
1993
The interlaminar fatigue crack growth behavior in a continuous carbon fiber reinforced poly(phenylene ether ketone) composite is studied. Experiments are conducted on double cantilever beam(DCB) specimens under mode I lo d controlled cyclic loading with a ratio of maximum to minimum load of 0.5. The delamina ion growth rate data are correlated with the corresponding maximum strain energy release rate by a power law. The resistance curve phenomenon is also found in the fatigue tests. The results of present study are discussed.
