  1. 1. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

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

    Author : Danilo Esteban Ortiz Sarasty; [2023]
    Keywords : Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Abstract : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

  3. 2. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johannes Fernberg; [2022]
    Keywords : Dielectric strength; composite; GFRP; glassfibre; composite microstructure; FEA; electric breakdown; single fibre;

    Abstract : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.

  4. 3. Geometric Quantization

    University essay from Uppsala universitet/Teoretisk fysik

    Author : William Hedlund; [2017]
    Keywords : Geometric Quantization; symplectic geometry; fibre bundle; quantum mechanics; quantization;

    Abstract : We formulate a process of quantization of classical mechanics, from a symplecticperspective. The Dirac quantization axioms are stated, and a satisfactory prequantizationmap is constructed using a complex line bundle. Using polarization, it isdetermined which prequantum states and observables can be fully quantized. READ MORE

  5. 4. Piezoelectric behaviour of woven constructions based on poly(vinylidene fluoride) bicomponent fibres

    University essay from Högskolan i Borås/Institutionen Textilhögskolan

    Author : KARIN RUNDQVIST; [2013]
    Keywords : Piezoelectricity; poly vinylidene; fluoride ; PVDF ; ; bicomponent fibre; conductive fibres; textile sensor; tensile sensor; weaving;

    Abstract : During this project it was investigated how the newly developed piezoelectric PVDF bicomponent fibre behaved when integrated in different weave constructions. The possibility to integrate conductive yarns as outer electrode was studied in order to see if it was possible to create a fully textile piezoelectric sensors. READ MORE

  6. 5. Bundles and Gauges, a Math-Physics Duality - the case of Gravity

    University essay from Teoretisk fysik

    Author : David Mendes; [2012]
    Keywords : Physics; Mathematics; Fibre Bundles; Gauge Theory; Gravitation;

    Abstract : A modern and straight forward summary of the necessary tools andconcepts needed to understand and work with gauge theory in a fibre bundle formalism. Due to the aim of being a quick but thorough introductionfull derivations are rarely included, but references to such are given wherethey have been omitted. READ MORE
