  • Influence of temperature and water on mechanical properties
  • Interactions of fibres and water – product demands
  • Influence of moisture on mechanosorptive creep

Learning objectives:

The student will after the course have a fundamental understanding of the;

  • mechanisms controlling moisture sorption and water-induced swelling of fibres,
  • influence of moisture sorption on the mechanical properties of fibres and papers,
  • mechanosorptive behaviour of paper and paper products,
  • factors controlling liquid imbibition into fibrous networks, and
  • limitations of fibrous products due to the interaction between water and fibres.
