Course information

Content and learning outcomes

Course contents *

A basic understanding of how fibers from mainly wood can be liberated from the wood, characterized and modified to be used in such different products as hygiene materials, packaging materials, different paper qualities and an insight into the research front for how fibers can be used in new materials for eg energy storage and advanced composites.

A large focus will be on

  • explaining how the hierarchical structure of the fibres is related to the properties of the materials produced by the fibres and the examples given in the course are collected from hygiene materials, packaging materials, paper and composites.
  • describing how fibres interact with moisture and water and how this can be described in a basic way and controlled to achieve optimal properties
  • giving examples of how fibres can be chemically and physically modified

Intended learning outcomes *

After completing the course the student should
To pass the course be able to:

  • Explain which chemical components that are included in the fibre wall, how they are affected by the fiber release processes and what task they have in the fibre wall.
  • Explain the importance of unit processes for fibre structure, chemical composition and surface chemical properties of the fibres
  • Relate how the properties of the cellulose fibres (physical and chemical) are related to the fibre network structure and the properties of the fibre materials
  • Use selected literature and present a compilation in the form of written report and oral presentation

to get a higher grade than E be able to:

  • Explain how fibres interact with water using thermodynamic basic principles and how this affects the properties of fibre based materials.
  • Summarize which advanced experimental methods are available to characterize the structure, chemical and surface chemical properties of the fibres.
  • Describe how fibres can be modified via chemical and physical methods and how these can be used in existing and new materials.
  • Explain how synthetic fibres are manufactured and explain the relationship between chemistry, process and physical properties
