  1. 6. Modification of lignin derivatives for polymerization in water

    University essay from KTH/Ytbehandlingsteknik

    Author : Adrian Södergren; [2022]
    Keywords : biobased monomer; ferulic acid; radical polymerization; styrenic mononer; lignocellulose; biobaserad monomer; ferulsyra; radikalpolymerisation; styrenliknande monomer; lignocellulosa;

    Abstract : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. READ MORE

  3. 7. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Rasmus Fredheim; [2021]
    Keywords : ;

    Abstract : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.

  4. 8. Structural temperatures of wind turbine blades under icing conditions

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Elise Brouillette; [2021]
    Keywords : Aerodynamics; Anti-icing Systems; Glass transition temperature; Heat transfer; Wind turbines;

    Abstract : As clean energy demand is on the rise and the wind energy sector in growth, locations with the highest wind potential are becoming of higher interest for wind farm projects, but they are located in colder regions. In cold climates, ice accumulation on wind turbine blades is a serious issue, both in terms of safety and performance. READ MORE

  5. 9. Viability of PEEK for high-temperaturemicrovascular composites manufacture

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Yago Domínguez Muñoz; [2021]
    Keywords : Materials; composite; microvascular; PEEK; high-temperature;

    Abstract : Microvascular composites are materials with an inner hollow network which allows thecirculation of fluids. This functionalizes the composite materials, giving them furtherapplications such as self-healing or active cooling. READ MORE

  6. 10. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.

    University essay from Karlstads universitet

    Author : Kajin Muradparist; [2021]
    Keywords : Stretchable; Barrier; Coating; WVTR; WVP; Hydroforming; Töjbar; Barriär; Bestrykning; WVTR; WVP; Hydroforming;

    Abstract : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. READ MORE
