16. 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
17. Characterisation of delamination properties in paper materials
Sammanfattning : .... LÄS MER
18. Fibre reinforced concrete : fracture mechanics methods applied on self-compacting concrete and energetically modified binders
Sammanfattning : Fibre reinforced concrete (FRC) is a type of building material that is increasing in use. As new types on concrete develops the need to update the knowledge on the use of fibre reinforcement increases. This thesis covers test methods for FRC that ranges from standard beam tests to sophisticated uniaxial tension tests. LÄS MER
19. Fibre surface properties of kraft pulp : The influence of wood raw material, bleaching and storage
Sammanfattning : The aim of this thesis was to study the fibre surface properties of Birch (Betula ssp.), Eucalyptus (E. urograndis and E. globulus) and Spruce (Picea Abies) pulps bleached using two different methods: ECF (Elementary Chlorine Free) and TCF (Totally Chlorine Free). LÄS MER
20. 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
