The possible role of microfibril angle of Hemp fibre during fatigue tests and its determination using Wide-Angle X-ray diffraction

The orientation of the microfibril of cellulose in cell wall undeniably plays a predominant role in the elastic properties of natural fibres. In particular, the reorientation of the microfibrils is supposed to be involved in the stiffening phenomena of fibres under cyclic loading. In order to measure the MFA on natural fibres, this work proposed a method based on Wide Angle X-ray Scattering (WAXS). The ultimate goal of this work is to couple cyclic loading and MFA measurement in the near future.
