Abstract

Graphical abstract: Highlights: The physico-mechanical properties of UBSBs with various densities and heat-treated bamboo sticks were studied. The UBSBs with various densities showed uniform density profiles. Most of the properties of the UBSBs increased with increasing density up to 1000 kg/m 3 . Heat-treated bamboo sticks significantly improved the dimensional stability of the UBSBs. The UBSB with 155 °C heat-treated bamboo sticks exhibited the best mechanical properties. Abstract: In this study, the effectiveness of density and heat treatment on the physico-mechanical properties of unidirectional round bamboo stick boards (UBSBs) made of Makino bamboo ( Phyllostachys makinoi ) was investigated. The result revealed that the density profiles of all UBSBs with various densities were uniform, and most of their properties increased with increasing density up to 1000 kg/m 3 . By increasing heat treatment temperature, the thickness swelling and water absorption of the UBSBs significantly decreased. Additionally, the UBSB with 155 °C heat-treated bamboo sticks exhibited the best mechanical properties among all UBSBs, and then it decreased as the heat treatment temperature increased further.
