Abstract
Natural fibre composites are prone to adsorb moisture
from the environment which may lead to dimensional
changes, mold growth, degradation of mechanical
properties or other adverse effects. In this work we
develop a method for direct non-intrusive measurement of
local moisture content inside a material sample. The
method is based on X-ray microtomography, digital image
correlation and image analysis. As a first application of
the method we study axial transport of water in a
cylindrical polylactic acid/birch pulp composite material
sample with one end exposed to water. Based on the
results, the method seems to give plausible estimates of
water content profile inside the cylindrical sample. The
results may be used, e.g. in developing and validating
models of moisture transport in biocomposites.
