The effects of hydrothermal aging on creep properties of resin reinforced bioboard were studied by means of the three-point bending creep test under different hydrothermal aging time and stress levels. According to the time-stress equivalent principle, the main creep curves of resin reinforced bioboard under different aged times were constructed by shifting the creep curves under different stress levels into a master curve at reference stress levels which it was chosen at the minimum stress level in the range of stress levels considered in this study. Therefore, the long-term creep behavior of...
