  3. 2. Fibre flow mechanisms

    Författare :Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. LÄS MER

  5. 4. A Network Model Applied to Cellulose Fibre Materials

    Författare :Susanne Heyden; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network mechanics; Fibre network; Cellulose fibres; Fracture; Stiffness; Computer simulation;

    Sammanfattning : A network mechanics model for analysis of materials made of dry-shaped cellulose fibres is proposed. In terms of the model, the network is composed of fibres of arbitrary distribution in length, curvature, cross-section. stiffness and strength. The fibres are arranged in a random structure according to an arbitrary orientation distribution. LÄS MER

  7. 5. Needle Punching of Wet Cellulose Fibre Structure

    Författare :Maria Klingberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; out-of–plane; fibre orientation; needle punching; fibre network structure; paperboard; cellulose fibre;

    Sammanfattning : Needle punching of cellulose fibre structures was studied, in order to explore the possibility for a new method for bonding to be used in the paperboard industry. The interest in such subject was based on the need for stronger fibre-to-fibre bonding in the thickness direction of paperboard. LÄS MER
