1. Skalningseffekter av medelstora pölbränder i syrereducerad miljö
Kandidat-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER
2. Flame retardant treated wood : An investigation into phytic acid and its ability to act as a flame retardant agent
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : Flame-retardant coatings have been serving their purpose since the romans ruled Europe. These products have been developed through the years, by mixing and synthetizing solutions, which have resulted in effective, although questionable, products due to their impact on the environment and our health.

3. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). LÄS MER
4. Assessing the effectiveness of siloxane-based flame retardants
Master-uppsats, KTH/KemiteknikSammanfattning : Polyedrisk oligomer silsesquioxane (POSS) är molekyler som har en inorganisk ryggrad med organiska grupper fa ̈sta utan på. Själva kåren har en bur liknande form och har en hög termisk stabilitet tack vare kisel (Si) och syre (O) som den består av. LÄS MER
5. Brandteknisk dimensionering av limträkonstruktioner : En jämförelse mellan förenklad och analytisk dimensionering med avseende på materialåtgång
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanikSammanfattning : This thesis examines the possibility of saving material by using analytical design of fire protection of glued laminated timber structures instead of the standard simplified design approach. The thesis is based on an existing store building (building class Br2 and occupancy class 2B) where Tyréns AB has determined a fire exposure specific for the store building, which is used to simulate 30 minutes of fire.
