“…Before drying, the mats were immersed in pure water for 4 (four) hours to ensure similar level of water content inside the woven bamboo mat. Previous study on analysing effect of bamboo fibre treatment [14] indicated that 150 ∘ C drying temperature providing the most excellent mechanical properties. Lower mechanical properties were observed for the composite containing bamboo fibre treated in drying condition above 150 ∘ C due to structural changes.…”

Bamboo laminate composites could be the alternative materials in outdoor application. However, the life time prediction of this composite in humid environment became a concern considering hydrophilic property of the bamboo fibre. This research aimed to assess the changes of mechanical properties in the composite with the sorption of water. It employed hand lay-up method in developing the laminate composites with epoxy as the matrix and woven bamboo as the reinforced material. Water sorption characteristic was evaluated through a gravimetric analysis for different water immersion temperatures. The sorption on water was studied by four weeks immersion in room temperature as well as in elevated temperatures of 50∘ and 80∘C. Tensile test was performed to evaluate the mechanical properties of the composite. This research clearly showed the significant effect of bamboo fibre on the strength and water sorption behaviour of the composites. It was observed that the rate of water absorption depends on temperature of immersion. Larger debonding between the bamboo fibre and the epoxy matrix was found in higher water immersion temperature. The results of this study emphasized the importance of considering the deterioration of mechanical properties in outdoor applications of bamboo composite highly exposed to high temperature and humidity
