1. Development and characterisation of bast and basalt fibre hybrid polymer composites for automotive applications
Sammanfattning : Natural fibres such as kenaf, hemp, and flax, also known as bast fibres, offer several benefits such as low density, low cost, carbon dioxide neutrality, sustainability and renewability. In Europe, their composites are used intensively by almost all car manufacturers, mostly in interior applications. LÄS MER
2. Strengthening of timber structures with flax fibres
Sammanfattning : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. LÄS MER
3. Mechanical Analysis of Melamine-Formaldehyde Composites
Sammanfattning : Planar random fibre composite materials based on melamine-formaldehyde (MF), one of the hardest and stiffest isotropic polymers that is known, have been developed recently on an industrial scale. In this thesis the mechanical behaviour of these materials is systematically investigated for the first time. LÄS MER
4. Benefits of strengthening timber with fibre-reinforced polymers
Sammanfattning : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. LÄS MER
5. Biofoams and Biocomposites based on Wheat Gluten Proteins
Sammanfattning : Novel uses of wheat gluten (WG) proteins, obtained e.g. as a coproduct from bio-ethanol production, are presented in this thesis. A flame-retardant foam was prepared via in-situ polymerization of hydrolyzed tetraethyl orthosilicate (TEOS) in a denatured WG matrix (Paper I). LÄS MER
