Following our previous studies on bulk mechanical, interlaminar and static indentation/impact properties in dry conditions, the effects of exposure to various combinations of temperature and humidity on the mechanical response of reformed bamboo/aluminum laminates have been evaluated. The moisture absorption phenomenon of the reformed bamboo was studied in comparison with natural bamboo with and without a protective edge coating. It is shown that protection of the laminate edge with an appropriate polymeric material was effective in reducing the moisture absorption into the bamboo layer and thereby improving the residual mechanical performance of the laminates. The reductions in axial tensile strength and impact strength after prescribed aging treatments were at most about 30% of the original, while that of the aluminium/bamboo interlaminar shear strength was nearly 94% of the original strength. This is explained in terms of the difference in strength contributions and the preferential concentration of moisture at the laminar interface.
