Wood Strength Below Fiber Saturation
Easywoodmoisture effects
Below the fiber saturation point (about 30% moisture content), as the moisture content of clear wood decreases, its strength generally:
- ADecreases
- BStays the same
- CDrops to zero
- DIncreases
Show solutionHide solution
Answer: D. Increases
Below the fiber saturation point, bound water leaves the cell walls and they stiffen, so strength and stiffness rise as wood dries. Above the fiber saturation point, changes in free water have little effect on strength.
