Moisture Absorption and Desorption Behavior of Composites in Cyclic Hygrothermal Environment

摘要：

　　The moisture absorption and desorption behavior of CCF300/BA9916 composites in cyclic hygrothermal environment was investigated.The experiment was performed for 70 C/100 % RH,to find out moisture absorption as a function of time.The results show that the moisture absorption and desorption behavior of CCF300/BA9916 composites basically conforms the Fickian’s second law.After 36 days of moisture absorption,the composites reach the effective moisture equilibrium level,and the effective moisture equilibrium content is about 0.849 %.Hygrothermal environment destroys the interface of fiber and matrix; moisture absorption has reversible and irreversible destructive effect on CCF300/BA9916 composites.Reversible damage on fiber/matrix interface can be eliminated after desorption processing,while the irreversible damage still exists.
