Relationships between microfibril angle, modulus of elasticity and compressive strength in Eucalyptus wood

Maderas: Ciencia y Tecnología, 2014
Many traits are known to be important in determining the value of Eucalyptus wood as sawn tim-ber. The commercial importance of the microfi bril angle (MFA) for wood quality is well established for a range of softwoods, but is less clear for hardwood ...
