Sitka spruce wood specimens were heated at 120–140 °C and different relative humidity values (RHh), and their specific dynamic Young’s moduli (E′/ρ), mechanical loss tangents (tanδ), and CIELAB color parameters were measured at 25 °C and 60% relative humidity before and after the removal of water-soluble extractives. The E′/ρ and tanδ values were significantly decreased and increased, respectively, with increases in mass loss by heating at 100% RHh. After the removal of water-soluble… CONTINUE READING
