  1. 16. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Rasmus Fredheim; [2021]
    Nyckelord :;

    Sammanfattning : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.

  3. 17. Three-Dimensionally Printed Versus Conventionally Cured Polymer-Based Material For Interim Restorations.

    Master-uppsats, Umeå universitet/Tandläkarutbildning

    Författare :Mohammad Saad; Doaa Al-Jubouri; [2021]
    Nyckelord :;

    Sammanfattning : ABSTRACT Background. Three-dimensional (3D) printing is a manufacturing technique, based on building objects layer by layer. It has received more attention lately especially in the medical and dental fields. LÄS MER

  4. 18. Mechanical properties of compression moulded fibre composite sheets

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Jakob Engström; [2021]
    Nyckelord :;

    Sammanfattning : This master thesis project was carried out at a large international company in the forest industry. The company is currently interested in producing sheet formed composite materials with high wood fibre content that can be further processed and formed using conventional compression moulding.

  7. 20. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    Master-uppsats, KTH/Betongbyggnad

    Författare :Anton Frank; Andreas Fristedt; [2021]
    Nyckelord :Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Sammanfattning : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.
