Micro Fibrilar Angle

Microfibril Angle in Wood and its Biological Significance : Just an Introduction


  • What is it?
The microfibrils are highly ordered bundles of cellulose chains (the crystal modulus along fiber axis is greater than 100 GPa) that give strength and stiffness to the cell wall.
The microfibrils in the middle layer of the secondary wall S2 (approx. 80% of the thickness) form a right-handed spiral which makes an angle with the cell axis called the microfibril angle, MFA.
The MFAs were generally found to be larger in the lower and basal parts of a branch
