Cellulose microfibril angle in the cell wall of wood fibres

Biological Reviews, 2004
ABSTRACTThe term microfibril angle (MFA) in wood science refers to the angle between the direction of the helical windings of cellulose microfibrils in the secondary cell wall of fibres and tracheids and the long axis of cell. Technologically, it is usually applied to the orientation of cellulose microfibrils in the S2 layer that makes up the greatest ...

Modeling Radial Variation in Microfibril Angle of Scots Pine

Advanced Materials Research, 2011
Microfibril angle (MFA) was determined at each growth ring from disks at breast height (1.3 m) from four scots pine (Pinus sylvestris) trees grown in northeastern China. Significant variation in microfibril angle was observed among growth rings. MFA at breast height showed a decreasing trend from pith to bark for each tree.

Variation of microfibril angle and its correlation to wood properties in poplars

Journal of Forestry Research, 2004
The microfibril angle of seven poplar clones was determined by using X-ray diffraction technique. Microfibril angle, wood basic density, fiber length, fiber width and cellulose content were assessed for every growth ring at breast height for all sample trees. Significant variation in microfibril angle was observed among growth rings.

Semi-automatic measurement of microfibril angle on a microrobotic platform

2014 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO), 2014
This paper presents an implementation of a method to measure microfibril angle of paper fibers on a microrobotic test bench designed for testing the mechanical properties of paper fibers. The method is based on microscopic transmission ellipsometry and the components required for the measurements are integrated to the platform and the computation ...

The derivation of the cellulose microfibril angle by small-angle X-ray scattering from structurally characterized softwood cell-wall populations

Journal of Applied Crystallography, 2005
A method is presented for the measurement, using small-angle X-ray scattering (SAXS), of the microfibril angle and the associated standard deviation for the cellulose microfibrils in the S 2 layer of the cell walls of softwood specimens.

High spatial resolution and non-destructive evaluation of wood density and microfibril angle by NIR hyperspectral imaging

NIR News, 2017
Wood density and microfibril angle are strongly correlated with wood stiffness, shrinkage, and anisotropy. Understanding the spatial distribution of these values is critical for solid timber applications. In this study, near infrared (NIR) hyperspectral

Mechanical performance and cellulose microfibrils in wood with high S2 microfibril angles

Journal of Materials Science, 2010
Corewood and compression wood, both with high S2 microfibril angles, are the worst parts of the tree most in need of improvement in wood quality. This study focuses on the characteristics of cellulosic reinforcement in wood with high S2 microfibril angles lying between 35° and 60°, as well as the probable influence of these characteristics on wood ...
