  1. 1. Methodology for evaluation of long-term mechanical properties of viscoelastic materials

    Master-uppsats,

    Författare :NIKHIL JOSEPH EBI; [2023]
    Nyckelord :;

    Sammanfattning : Additive manufacturing (AM) enables the fabrication of complex geometries using layer-by-layerdeposition of materials like polymers and metals. However, predicting the long-term viscoelasticcharacteristics of AM polymer parts is challenging due to limited available data. LÄS MER

  3. 2. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mercedes Amelia Bettelli; [2020]
    Nyckelord :Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Sammanfattning : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. LÄS MER

  4. 3. Virtual characterization of composite materials for aero-engine components

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Facundo Masari; [2020]
    Nyckelord :Composite; simulation; multiscale; modelling; UD; NCF; prepreg; aerospace; engine;

    Sammanfattning : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. LÄS MER

  5. 4. Predicting Mechanical Properties of Polymer Films after Extrusion Coating using Supervised Machine Learning Algorithms

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Sara Khayyami; [2019]
    Nyckelord :Machine Learning; Predicting Polymer Properties; Mechanical Properties; Stress – Strain; Processed Polymer; Extrusion Coating; Technology and Engineering;

    Sammanfattning : Tetra Pak is a world leader in providing innovative packaging solutions and processing technologies and has been so for a very long time. It is well – known that the material used for packaging purposes gets subjected to high temperature and pressure during folding and filling which could compromise the integrity of the material.

  7. 5. Understanding product build up at packaging material surface to address food waste

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Ashri Nugrahini; Sonam Lhamo; [2019]
    Nyckelord :Yoghurt; Packaging material; Build up; Yield stress; Gravimetric dip test; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : Difficulty to empty the package is one of the main reason of food waste in yoghurt at consumer level with an estimated 5-10% of product residue being left on the packaging material. The phenomenon of product build up is explained by numerous hypothesis. However, these studies are empirical in nature. LÄS MER
