Focus on the hygrothermal environment problems of CF3031/CCF300 stiffened composite panel, the stiffened composite panel absorption were studied on in the 85%RH, 70℃ hygrothermal environment, the moisture equilibrium content of the composites were calculated. The shear test were carried on after hygrothermal aging, observed the change of the strain, and draw the conclusion of the flexural load and the breaking load, contrasted with the panel of before hygrothemal aging. The results show that
more » ... shear strength was correlated with glass transition temperature, and the rate of remained flexural load was about 85% and the rate of remained breaking load was about 75% after hygrothemal aging.
