Title Stress transfer and failure in pulp-fibre reinforced composites
Abstract I will present a project done in colaboration with STFI-Packforsk in Stockholm.

Natural-fibre composites are materials where natural fibres, such as pulp fibres, are used as reinforcement in a polymeric matrix. Experiments performed at STFI-Packforsk indicate that fibre-fibre bond strength, which has a strong effect on paper strength, does not affect the strength of pulp-fibre composites.

To further validate this result, the fibre-fibre bond strength of the studied sheets will be measured in 3D images of the sheets produced using X-ray microtomography. This is still a work in progress, but I will present some preliminary results and discuss my ideas for future development.
