1. Mass and Heat Transport in Dryer Fabrics - Experiments and Modelling
Sammanfattning : A dryer fabric is used in the multi-cylinder dryer in order to improve the runnability of the web and to establish proper contact between the web and the hot cylinder, thus improving the heat transport. The dryer fabric separates the hot and moist paper from the ambient drying air and significantly influences the mass and heat transport. LÄS MER
2. Through air drying : Thermographic studies of drying rates, drying non-uniformity and infrared assisted drying
Sammanfattning : The removal of water is an integral part of papermaking. The drying process is responsible for a great share of the energy used in the paper machine. Premium grade tissue products are dried by through air drying. Large volumes of natural gas are burned to heat the air drawn through the paper web to achieve the drying. LÄS MER
3. Fire behaviour of upholstered furniture component materials at multiple scales
Sammanfattning : In this research, both experimental test methods and computer models were used to characterise the thermal decomposition processes of selected upholstered furniture component materials, namely; flexible polyurethane foam and a range of different fabric coverings. This was first done at some of the smallest, simplest levels available, and how these materials were tested and the methods chosen to investigate them, was examined. LÄS MER
4. Stiffness characterization in Non-Crimp Fabric Composites
Sammanfattning : Lightweight materials with high stiffness and damage tolerance are requested for aerospace, marine and automotive industries. Many types of composite materials are today used in various types of load carrying structures, due to their excellent strength and stiffness to weight ratio. LÄS MER
5. Process modeling of liquid composite molding processes
Sammanfattning : The polymer matrix composites (PMCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and the corrosion resistance, the PMCs are wildly utilized from aerospace to automobile industries, both in the sectors of civilian and defense. LÄS MER
