The Effect of Environment on the Mechanical Behavior of AS/3501-6 Graphite/Epoxy Material. Phase III.

Abstract

The effect of temperature and moisture on the fatigue properties of AS/3501-6 Gr/Ep composite was investigated. Constant stress amplitude fatigue tests of test specimens and their data analysis were conducted. A probabilistic fatigue failure model derived from the concept of crack propagation has been used as a base for data/analysis correlation. Current data show that the degraded effective modulus of the in-situ matrix should be an important parameter in the analysis of fatigue life prediction. (Author)
