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

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

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

    Abstract : 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. READ MORE

  3. 7. Effect of Stainless Steel Additive Manufacturing On Heat Conductivity and Urea Deposition

    University essay from KTH/Materialvetenskap

    Author : Sabrina El Mouhib; [2020]
    Keywords : ;

    Abstract : Hydroforming is the manufacturing process that Scania uses to produce exhaust pipes with complex shape and high durability.  Selective Laser Melting is the process used by designers to print prototype pipes and perform emissions tests before mass production. READ MORE

  4. 8. Finite element modelling of strained nanowire heterostructures

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Alexander Grape Wyke; [2019]
    Keywords : Strain; nanowire; heterostructure; physics; nanophysics; COMSOL; simulation; lattice; Physics and Astronomy;

    Abstract : When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. READ MORE

  5. 9. Thermoelectric Cooler Prototype Based on Bismuth Telluride and Aimed for Space Applications

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Viktor Karlsson; [2017]
    Keywords : Thermoelectric cooler; bismuth telluride;

    Abstract : The main goal for this project was to design, manufacture and evaluate a thermoelectric cooler, TEC, prototype. One of the biggest challenges with TECs is that they need to be very reliable and have a long lifetime. READ MORE

  6. 10. Electrical Evaluation of a Low Concentrating PVT Collector Based on Performance Ratio

    University essay from Högskolan Dalarna/Energi och miljöteknik

    Author : Assem Abdel Rahman; [2015]
    Keywords : ;

    Abstract : Photovoltaic Thermal/Hybrid collectors are an emerging technology that combines PV and solar thermal collectors by producing heat and electricity simultaneously. In this paper, the electrical performance evaluation of a low concentrating PVT collector was done through two testing parts: power comparison and performance ratio testing. READ MORE
