Abstract

Highlights: Physicomechanical properties of 220 °C-treated bamboo significantly decreased. Most of flexural properties showed a positve relationship with apparent density. Correlation between flexural properties and density was using linear relationships. Water absorption ( WA ) of all bamboo increased with decreasing apparent density. Correlation between WA and density was described using exponential decay equations. Abstract: The effects of treatment temperature on the physicomechanical properties and dimensional stability during water immersion of moso bamboo were investigated as a function of density. The results indicated that most of the physical and flexural properties and dimensional instability significantly decreased when the temperature increased to 220 °C. Additionally, the flexural properties of untreated and heat-treated bamboo showed a positive relationship with the apparent density, while their water absorption ( WA ) increased with decreasing apparent density. Furthermore, despite the treatment temperatures, the modulus of elasticity and WA for all the bamboo samples were better described using linear relationships and exponential decay equations, respectively.
