    Sammanfattning : The development of sustainable and renewable materials is paramount in today’s society. As the most abundant biopolymer on Earth, cellulose from cellulose-rich fibres is an excellent alternative for advanced and innovative material solutions. LÄS MER

  4. 13. Micro-mechanical characterization and modeling of paper and paperboard

    Författare :August Brandberg; Artem Kulachenko; Sören Östlund; Carl Dahlberg; Rami Mansour; Ron Peerlings; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (paperboard). This thesis investigates the mechanical performance of paper and paperboard via micro-mechanical modeling and presents new methods for the mechanical characterization of the micro scale, necessary in such models.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D fiber network structure; foam forming; numerical modeling; compression simulation; orientation; wall-bounded flow; CFD; Jeffery orbits; LS-DYNA;

    Sammanfattning : Fiber networks are ubiquitous and are seen in both industrial materials (paper and nonwovens) and biological materials (plant cells and animal tissues). Nature intricately manipulates these network structures by varying their density, aggregation, and fiber orientation to create a variety of functionalities. LÄS MER
