Effect of Thickness of Microtome Sections on Their Tensile Properties
AbstractTangential microtome sections of loblolly pine of varying thickness (earlywood from 0.00300 inch to 0.01150 inch, latewood from 0.00150 to 0.00730 inches) were sliced, using two different slicing arrangements. All microtome sections were tested wet in tension. The results demonstrate that irrespective of the slicing arrangement, a high degree of association exists between tensile properties (tensile strength, tensile stiffness) and thickness of microtome sections.
