Improved uniformity of the fibers liberated in the kraft pulp digester

This project sets out to elucidate mass transport characteristics during delignification of wood chips as a means of understanding and controlling non-uniform delignification effects, associated to low efficiency and poor property control in the current pulping processes. To obtain information on local variations of delignification effect in a wood chip, the treated chips will be […]

Modeling, processing and optimization of highly-filled polymer wood fiber composites

TREESEARCH

Biocomposites are a critical ingredient in the context of overarching societal efforts to increase the use of renewable materials. Therefore, the use of polymer with natural fiber reinforcements is expected to increase significantly. A current drive for polymer biocomposites is to maximize the use of renewable content in mass production systems. However, the full potential

Cellulose fibre/fibre interactions within molded fibre composites

TREESEARCH

This project aims to model cellulose fibre/fibre interactions using assembled CNF filaments produced by co-axial extrusion. These long, uniform filaments provide an excellent platform to investigate the impact of chemical and physical modification on joint strength. The findings of this work can then be used to a develop a better understanding of the interactions within
