1. A Model for Simulation of Fiber Suspension Flows
Abstract : The fiber suspensions in the production line from wood topaper are subjected to many types of chemical and mechanicalprocesses, in which the flow of the suspension is of vitalimportance. The flow of the suspension determines the degree ofuniformity of the fibers through the processing, which inreturn affects the properties of the fiber suspension. READ MORE

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

3. Micromechanics of Fiber Networks
Abstract : The current trends in papermaking involve, but are not limited to, maintaining the dry strength of paper material at a reduced cost. Since any small changes in the process affect several factors at once, it is difficult to relate the exact impact of these changes promptly. READ MORE

4. The effects of cellulosic fiber charges on polyelectrolyte adsorption and fiber-fiber interactions
Abstract : The surface charges of cellulosic fibers contribute to several papermaking operations that influence the manufacture and final properties of paper. This thesis investigates the effect of the surface charges on wet-end chemistry, e.g. READ MORE

5. A Network Model Applied to Cellulose Fibre Materials
Abstract : 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. READ MORE
