dc.description.abstract | Fibre bonds play an essential role in various properties of paper. Much research has focused on their
strength, but the determination of the actual contact area also provides a challenge. Many of the
research methods rely on optical tools, which are restricted by the wavelength of light that is utilised.
Novel X-ray computed tomography devices utilise X-rays in studying the inner structure of materials,
and surpass the optical methods in terms of resolution, allowing detection of even smaller details and
variations in distance between the fbres in the bond intersection area. X-ray nanotomography was used
to image 26 individual cellulose fbre bonds made of springwood and summerwood fbres of refned
bleached softwood kraft pulp. Various dimensional properties of the bonds were measured, most
importantly the relative contact area (apparent contact area/intersection area), whose values showed
wide variation from 6.4 to 85% with an average of 57.7%. Although the summerwood bonds had a
somewhat smaller intersection and contact area than springwood bonds, there were no signifcant
diferences in the relative contact area between the bond types. This suggests that the efect of relative
and absolute contact area on the strength diferences between bond types seems to be minor. | fi |
