Abstract The moisture absorption and desorption behavior of CCF300/BA9916 composite laminates in 70℃ distilled water was investigated. After the moisture absorption and desorption experiments, the static tensile performances of CCF300/BA9916 composites in three conditions were investigated. The results show that the moisture absorption and desorption behavior of CCF300/BA9916 composites basically conforms the Fick’s second law. After 35 days of moisture absorption, the composites reach to the effective moisture equilibrium level, and the effective moisture equilibrium content is about 0.85%. Compared with the dry one, the static tensile performances of CCF300/BA9916 composite laminates decreased due to moisture absorption, while the desorption process makes it some recovery.
