Fatigue of Composites at Cryogenic Temperatures

Source

A comparison has been made between the wearout rates of [0/± 45/0] boron/epoxy and boron/aluminum composites in low-cycle fatigue at 295 and 76 K. Using degradation of modulus as the wearout criterion, these preliminary data indicate that cryogenic temperatures have a negligible effect on either tensile or compressive fatigue performance of boron/epoxy. A similar indication was obtained for boron/ aluminum in tensile fatigue. These conclusions are substantiated by high-cycle fatigue results on boron/epoxy.
