dc.description.abstractIn this study the effect of embedded sensor tube on fatigue life of composite structure under compression fatigue has been determined. Specimens were prepared using carbon/epoxy prepregs stacked in [(90/0/90)3 90/0]s with sensor embedded in the midplane between two 0° plies. The tests were performed at frequency of 5Hz, R = 10 at different stress levels and the results plotted on S-N plot clearly show a reduction in fatigue life with the run-out cycle for specimen with sensor tube reduced to almost 70% of the static compression strength compared to 80% for the specimens without sensor tube. In all the cases the failure was sudden, catastrophic, showing brooming kind of failure and in no instance the sequence of failure could be determined. Later the microscopy study revealed the crack initiating at the crack tip of the “resin-eye” and arresting at the sensor tube, mode of failure could not be inferred from this observation.
