Fatigue Behavior of Continuous Carbon Fiber-Reinforced PEEK

Source

This paper examines fatigue behavior for AS4/PEEK and IM6/PEEK laminates. Tensile fatigue data in the form of stress-log n curves are shown for multiangle ply laminates at 23 and -55°C. Fatigue behavior is also examined for ±45 laminates at different cooling rates from the melt during consolidation. Compressive fatigue data are reported for 40-ply unidirectional laminates at test temperatures of 23 and 120°C. Again, the influence of cooling rate from the melt is explored. The paper also attempts to discuss an interpretation of the results in terms of the expected failure mechanisms that occur for these laminates and the chosen stress fields.
