  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

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

    Author : Sara Muminovic; Christina Lindén; [2023]
    Keywords : Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Abstract : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. READ MORE

  3. 2. On the Mechanical Recycling of Woven Fabrics : Improving the Reusable Fibre Yield of Mechanical Methods

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Ludvig Johansson; [2020]
    Keywords : Textile; fabric; textiles; fabrics; mechanical; recycling; woven; weave; yarn; cotton; twill; satin; diamond; Textil; textilie; textilier; väv; garn; återvinning; mekanisk;

    Abstract : This master thesis studies the recycling prospects of textiles. The textile industry contributes negatively to the global environmentthrough the release of greenhouse gases and consumption of resources. In order to achieve a circular textile industry, textiles must be recyclable by both chemical and mechanical means. READ MORE

  4. 3. Aerodynamics and Structure of a Large UAV

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Oscar Vestlund; [2018]
    Keywords : ;

    Abstract : This thesis investigates what design of a large UAV performing VTOL using only electrical motors is the most viable in terms of extending its range. Because it uses batteries for power, its powered time is limited, posing the need for a way of extending its flight time. READ MORE

  5. 4. Development of Dynamic Test Method and Optimisation of Hybrid Carbon Fibre B-pillar

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Johansson; Markus Lindmark; [2017]
    Keywords : Dynamic test method; B-pillar; Crash worthiness; Side impact crash test; IIHS; Carbon fibre reinforced polymer composite; Composite failure; CFRP; UD; 2x2 Twill; Delamination; Finite Element Method; LS-Dyna; Steel-composite interface; Bilinear fracture toughness;

    Abstract : The strive for lower fuel consumption and downsizing in the automotive industry has led to the use of alternative high performance materials, such as fibre composites. Designing chassis components with composite materials require accurate simulation models in order to capture the behaviour in car crashes. READ MORE

  6. 5. Shape Distortion Analysis of Self-Reinforced Poly(ethylene terephthalate) Composites : The PETrifying reality!

    University essay from KTH/Lättkonstruktioner

    Author : Calle Eliasson; [2016]
    Keywords : ;

    Abstract : Composite components with a V-shaped geometry have been manufactured through compression moulding of fabrics based on self-reinforced poly(ethylene terephthalate). The fabrics were subjected to a set of predetermined degrees of stretching during manufacturing with the intent to investigate its effects on shape distortions in terms of spring-in and warping.
