Book excerpt: The main objective of this research investigation was the effect of compressive loading on the fatigue response of graphite epoxy laminates as influenced by a circular hole and an aggressive environment. The investigation was undertake n in order to further characterize the behavior of graphite/epoxy laminates under fatigue loading. The primary emphasis of the program was on the accumulation of a statistically significant data base. Unnotched coupon properties of a quasi-isotropic and a 67% 0 degrees fiber laminate were investigated in a 82.2 degrees C (180 degrees F), 90% R.H. environment after prior conditioning in that environment. The interactional effects of absorbed moisture and fatigue loading on the fatigue lifetime of coupons containing a circular hole was investigated at room temperature and at 82.2 degrees C (180 degrees F), 90% R.H. using the quasi-isotropic laminate. The test program consisted of static tension and compression tests; tension-tension and tension-compression fatigue tests; and static tension and compression residual strength tests of coupons prior tested either under tension-tension or tension-compression fatigue loading.
