The effect of the environment on the fatigue properties of ARALL-3

The effect of the environment on the fatigue behaviour and residual strength of ARALL-3 has been studied using three types of specimens, varying in structural complexity. In addition to the reference ambient air condition, specimens were aged and/or fatigue loaded in hot/humid air or in sump tank fluid. Environmental fatigue loading of door...

Standardized environmental fatigue sequence for the evaluation of composite components in combat aircraft (ENSTAFF = ENvironmental FalSTAFF)

Fatigue life assessment of composite structures in fighter aircraft necessitates testing with both mechanical and environmental loading at both coupon and structural element size levels. Testing facilities to run such tests are now available but environmental fatigue testing is expensive and time consuming. An environmental fatigue loading...
