The effects of changes in test temperature from 25 to - 125degreesC on the fatigue crack propagation of 2080/SiC/20p-2080 adhesive bonded laminates (ABL) with volume fraction ratio of 60/40 tested in the crack arrestor orientation were investigated. The fatigue behavior of the laminates was significantly different than that of the individual laminae as well as other types of laminates (i.e., diffusion bonded laminates). The fatigue crack growth behavior of the ABL's was significantly affected by the test temperature, particularly when the fatigue cracks approached and entered the adhesive layers. In-situ monitoring of fatigue crack growth and post mortem analyses were used to determine the likely source(s) of the effects of changes in test temperature and differences between the ABL and its constituents.
