Abstract

The present research work has investigated the PHYSICAL AND MECHANICAL PROPERTIES of hygrothermally modified poplar (Populus deltoides L.) wood. The poplar wood blocks were treated hygrothermally at temperatures of 130, 150 and 170oC and for 20, 40 minutes TREATMENT TIME. The PHYSICAL AND MECHANICAL PROPERTIES were determined for both treated and untreated wood. The properties; mass loss, collapse, specific gravity changes, dimensional stability, surface roughness, bending strength and modulus of elasticity, were determined prior to and after the treatment in all wood blocks. The hygro-thermal treatment significantly improved the dimensional stability of the samples. It was also found that the hygro-thermal treatment increased collapse, surface roughness and modulus of elasticity due to the treatment. However, wood mass, specific gravity and bending strength of the treated poplar wood decreased. It was revealed that the mass loss, density reduction as well as collapse in wood are correlated with treatment temperature as well as the TREATMENT TIME. While, higher treatment temperature TREATMENT TIME increases the dimensional stability.
