  1. 1. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Författare :Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. LÄS MER

  3. 2. Nanostructured Cellulose Biocomposites : Effects from dispersion, network and interface

    Författare :Mohd Farhan Ansari; Lars Berglund; Jean-Francois Gerard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; cellulose nanofibrils; hygromechanical properties; network structure; thermoset; polymer matrix composites; natural fiber composites; pulp fiber; strain hardening; humidity; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The major load bearing component in native wood, cellulose nanofibrils, are potential candidates for use as reinforcement in polymer matrices. This study is based on nanocellulose composites and attempts to prepare and characterize biocomposites with high nanocellulose content and investigate the influence of nanostructure on macroscopic properties.

  4. 3. Hygro-Mechanics of Wood Fibre Composite Materials

    Författare :Kristian Stålne; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; homogenisation; Wood composite materials; modelling; stiffness; hygroexpansion; creep; mechanosorption;

    Sammanfattning : The work presented in this thesis deals with modelling and testing of hygro-mechanical properties of wood fibre composite materials. The material studied experimentally is high pressure laminate, HPL, which is a wood fibre network composite, made up of craft paper impregnated with phenolic or melamine resin. LÄS MER
