  1. 1. Evaluation of the Weather Resistance of Ram-Air Kites Used in Airborne Wind Energy Systems

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Johanna Désirée Ambs; [2023]
    Keywords : Weathering Resistance; Coated Textiles; Ram-air Kite; Airborne Wind Energy;

    Abstract : Airborne Wind Energy is an emerging technology that harnesses the power of the wind by using tethered wings. Among the flying devices are ram-air wings made from coated textiles that utilize dynamic pressure to gain their shape. READ MORE

  3. 2. Polymer Directed Engineering of Novel Cellulose Network

    University essay from KTH/Fiber- och polymerteknologi

    Author : Christel Gradin; Adina Landström; Julia Szecsödy; [2021]
    Keywords : Hydrogel; Carboxylated CNF; TEMPO-oxidation; bis-MPA ammonium dendrimer; Polymer salt bridge; Rheology;

    Abstract : This study investigated a CNF/dendrimer hydrogel and how different concentrations of the carboxylated CNF and bis-MPA ammonium dendrimer affected the hydrogels’ rheological properties. A third generation bis-MPA ammonium dendrimer was diffused into a dispersion of carboxylated cellulose nanofibrils. READ MORE

  4. 3. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations

    University essay from Lunds universitet/Mekanik

    Author : Theodor de Sousa; [2020]
    Keywords : peridynamics; peridigm; harmonic-structured materials; computational mechanics; fracture modelling; Technology and Engineering;

    Abstract : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. READ MORE

  5. 4. Abaca in the Philippines, an overview of a potential important resource for the country : Relating the tensile strength of the single fiber to the microfibrilar angle

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

With theincreasing demand for renewable materials such as bio-based fibers, the research aroundnatural fibers is intensifying. READ MORE

  6. 5. Mechanical properties of films made of faba bean protein nanofiber and non-fibrillated protein

    University essay from SLU/Department of Molecular Sciences

    Author : Alice Dunge; [2019]
    Keywords : Faba bean; amyloid; fibrils; meat substitutes; elasticity; stiffness; proteins;

    Abstract : The production of livestock puts a huge strain on our ecosystem and the planet. It is the largest source of greenhouse gases and it causes loss in biodi-versity and pollution of water. One way to reduce these environmental dam-ages is to decrease the intake of meat and increase the intake of plant-based proteins. READ MORE
