“…Blade laminates may be subjected to various combinations of cyclic fatigue loading and static or cyclic creep loading, and the material response may be sensitive to time or cycles to varying degrees depending on R-value, load level, etc 1,[8][9][10] . Fiber dominated loading with unidirectional glass fibers produces time effects deriving from static fatigue of the glass fibers 11 , while off-axis, resin dominated response, as with ±45 o plies, produces effects related to the viscoelastic response of the resin 12 .…”

The creep and fatigue behavior of double bias (±45) glass/epoxy laminates has been explored with a variety of tests, including conventional sine-wave fatigue loading at six loading conditions (R-values), residual property stress-strain tests, square wave fatigue tests, creep tests, and loading-unloading-reloading (LUR) tests. The fatigue results are presented as a strain-based constant life diagram (CLD) representing a 50% strain increase which correlates with a transition to rapid strain increase and failure. Reversed loading effects are explored in detail, and show a substantial creep response during both the tensile and compressive parts of the wave-form, which correlate with creep test data. The baseline epoxy resin is compared with a urethane resin, showing the effects of a tougher but more creep sensitive resin on the creep and fatigue resistance for unidirectional and ±45 laminates.
