    Sammanfattning : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. LÄS MER

  4. 4. Improved side impact car safety : New IIHS side crash regulation, effect on product design

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Andreas Bäckman; [2022]
    Nyckelord :Side impact beam; IIHS; side crash; side impact crash testing; crash testing of automobiles; industrial design engineering; automotive design; product design; Sidokrockskydd; IIHS; sidokrock; sidokollision; sidokrocktestning; krocktest av bilar; teknisk design; bildesign; produktdesign;

    Sammanfattning : 23% of passenger vehicle occupant deaths in 2019 was side-impact collisions and is a ongoing problem that continues to take people’s lives (IIHS, 2021a). IIHS (Insurance Institute for Highway Safety) is an organization based in USA, which performs vehicle crash tests with the goal of making cars safer and reducing deaths and injuries. LÄS MER

  5. 5. 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.
