Effects of fire-retardant resin treatment and redrying temperature on mechanical properties of hinoki wood

In this study, to determine the effects of fire-retardant treatment and redrying temperature on certain mechanical properties of hinoki wood, the MOR (modulus of rupture), MOE (modulus of elasticity) in bending and dynamic MOE in bending of control and fire-retardant chemically wood treated under redrying temperatures were estimated. The drying time was shorter with an increase in redrying temperature, and the average drying rate of the water-treated wood was greater than that of the fire-retardant-treated wood. The drying curves of fire-retardant-treated wood were nearly parallel in the early redrying period. The dynamic and static MOE of the water-treated wood were reduced compared to the control. The MOR was increased slightly with an increase in the redrying temperature.
