16. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy
Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER
17. On Zero-dimensional Modelling of Combustion and NOx Formation in Diesel Engines
Sammanfattning : Diesel engine developers are facing major challenges when meeting future demands on NOx and particulate emissions. The exhausts after treatment systems are rapidly improving and the technologies available in a few years will be capable of cutting emission levels close to the demanded levels. LÄS MER
18. Transparent Wood Biocomposites for Sustainable Development
Sammanfattning : Sustainable wood nanotechnologies that combine optical transmittance and mechanical performance are interesting for new functionalities utilizing transparency. Wood is a sophisticated bio-based material with a natural hierarchical, anisotropic and porous structure. LÄS MER
19. An Experimental Investigation of Shape Distortions in Aerospace Composites
Sammanfattning : Composite materials are increasingly used in primary structure of modern commercial aircraft. Its excellent material characteristics enables reduction of structural weight compared to traditional metal solutions and thereby offers reduction of fuel consumption and carbon dioxide (CO2) emissions.
