Tensile strength of spruce

WebThe immediate tensile strength parameters for spruce parallel to the grain and for hardboard have been determined at equilibrium conditions at temperatures up to 250°C. Below 100°C the moisture content has been varied between 0 and 30%. Above 100°C dry samples have been studied. An increase in moisture content up to about 12% leads to a … WebWood - Compressive Strength vs. Moisture Content - Red Spruce, Longleaf Pine and Douglas Fir - moisture content and their compressive strength.
