Abstract
The use of fiber reinforced polymer composites in structural applications, especially when submitted to hygrothermal loads, requires a thorough knowledge of the behavior during the life in service. Due to the viscoelastic response and the manufacturing method the time dependent behavior is studied in carbon/epoxy rings manufactured by filament winding. Test specimens with different stacking sequences were tested for creep under constant radial load for periods of 240 h in three hygrothermal conditioning variations. Through the creep curves and experimental analyzes a modification in the rigidity and the behavior of the material was verified, showing that the properties were affected by the time and conditioning, especially when above the ambient temperature.
