1. 16. Bedömning av prediktiv förmåga för Finita Elementberäkningar med optisk töjningsmätning (DIC)

   Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Albin Zetterqvist; Linus Hjelm; [2023]
   Nyckelord :Digital image correlation; Finite element; Predictive capability; Model calibration; FEM; DIC; Modellkalibrering;

   Sammanfattning : The goal of this thesis is to improve the predictive capability of Finite element (FE) by gathering data from experimental test and implement the characteristics into the material model that is used. FE is a commonly used method to predict the mechanical behavior of materials and components during applied forces. LÄS MER

3. 17. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

   Master-uppsats, Lunds universitet/Innovation

   Författare :Juliana Kalling; Tora Abrahamsson; [2023]
   Nyckelord :Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

   Sammanfattning : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. LÄS MER

4. 18. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Elise Meurs; [2023]
   Nyckelord :Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

   Sammanfattning : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.

5. 19. Size effect in wood : Characterization of mechanical properties using digital image correlation method

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

   Författare :Amir Saeidi; Olafur Johannsson; [2023]
   Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

   Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER

7. 20. Biokonvertering av Brödavfall till Svampfilmer för Textila Applikationer

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Samira Syed; [2023]
   Nyckelord :Filamentous Fungi; Aspergillus oryzae; Food Waste; Bread Waste; Wet-laid; Casted; Tara; Myrobalan; Quebracho; Chestnut; Tannin;

   Sammanfattning : Bread waste represents a significant portion of global food waste, necessitating innovative approaches for its valorization. This research project explores the utilization of bread waste through fermentation with Aspergillus oryzae to produce fungal film which could be used for textile applications. LÄS MER
