1. Towards the production of conductive and piezoelectric bicomponent textile fibres
Sammanfattning : In the present study electrical conductive and piezoelectric textile fibres have been manufactured and characterized. Potential applications of these fibres are for example textiles with heating and sensor properties. LÄS MER
2. Manufacturing and Characterisation of Conductive and Piezoelectric Textile Fibres
Sammanfattning : This thesis explores the manufacturing and characterisation of melt spun electrically conductive polymer nanocomposites and piezoelectric textile fibres. Potential applications of these fibres are for example textiles with heating and sensor capabilities. LÄS MER
3. Atoms in Lithiated Carbon Fibres
Sammanfattning : Carbon fibres are key constituents of structural batteries, in which electrochemical energy storage and mechanical load bearing are merged in one multifunctional device. Here carbon fibres simultaneously act as structural reinforcement by carrying load and as battery electrode by hosting lithium (Li)-ions in its microstructure. LÄS MER
4. On the production of polyethylene dielectrics and conductive polymer composite fibres
Sammanfattning : Foamed cable insulations and conductive polymer composite fibres are two applications in polymer processing where the electrical properties of a material may be altered significantly during processing. Their common denominator is that the outcome depends to a large degree on the flow behaviour of the polymer melt, in particular the melt extensional properties. LÄS MER
5. Fluid dynamics and flow structures of wood fibres suspended in gas flows
Sammanfattning : The flow of wood fibres suspended in gas plays a major role in the MDF (Medium Density Fibreboard) production process. Development of machinery in this industry has traditionally been based on experience. Only recently has the use of numerical methods such as CFD (Computational Fluid Dynamics) become an important part of the development process. LÄS MER
