摘要：Untreated and 160 degrees C, 180 degrees C, and 200 degrees C thermo-treated bamboo bundle curtains were reconstructed to make high-density board by impregnation with phenol-formaldehyde resin. The physical and mechanical properties of the boards were examined to evaluate the effect of temperature on their qualities. The modulus of rupture decreased with the increase in thermo-treatment temperature and was reduced by nearly 50 percent after 200 degrees C treatment; however, the modulus of elasticity and bonding shear strength did not change much between untreated and thermo-treated specimens. Thermo-treatment improved the dimensional stability of the boards. Thickness swelling after water immersion and wet-dry cyclic testing decreased with increasing thermo-treatment temperature. Compared with the control specimens, the total color difference (Delta E*) changed greatly as the thermo-treatment temperature increased. The chemical and Fourier transform infrared spectroscopy results showed that the major component content and functional groups in the major components changed after thermo-treatment.
