1. Swelling of Cellulose Fibrillar Matrices and Gels
Sammanfattning : One of the major challenges of today´s society is to find a sustainable way to create a living based on the resources on earth. It is a challenge that includes a transition from fossil-based materials to renewable/biodegradable raw materials and also the creation of an environmentally friendly circular material flow. LÄS MER
2. Micromechanical Modelling of Wood and Fibre Properties
Sammanfattning : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. LÄS MER
3. On the Modelling of Mechanical Dewatering in Papermaking
Sammanfattning : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. LÄS MER
4. Wood-fibre composites : Stress transfer and hygroexpansion
Sammanfattning : Wood fibres is a type of natural fibres suitable for composite applications. The abundance of wood in Swedish forests makes wood-fibre composites a new and interesting application for the Swedish pulp and paper industry. LÄS MER
5. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation
Sammanfattning : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. LÄS MER
