  1. 16. Polyimide thin-ply composite

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

    Författare :KHALID MOUANE; [2018]
    Nyckelord :Polyimide; thin-ply; microcracking; curing stress; mechanical loading;

    Sammanfattning : Mechanical performance of composite structures is influenced by the accumulation of damage from the manufacturing process and throughout the whole service life. For instance, an aircraft is subjected to a combination of mechanical loading and the thermo-oxidative environment from the take-off to the landing. LÄS MER

  3. 17. Development of Robust Automated Handling of pre-impregnated Carbon Fibre

    Master-uppsats, Linköpings universitet/Industriell Produktion

    Författare :Fredrik Martinsson; [2018]
    Nyckelord :Composite Automation; Automated CFRP Layup; Prepreg; Pick and Place;

    Sammanfattning : Prepreg is a fibre reinforced polymer composite material often used by the aeronautical industry. The material supplier has pre-impregnated the fibre often with an epoxy resin and cured it to a semi-viscous B-stage where the material is tacky (adhesive). LÄS MER

  4. 18. Early assessment of composite structures

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Priyank Gupta; Srikanth Ananthasubramanian; [2018]
    Nyckelord :;

    Sammanfattning : To meet the need of lightweight chassis in the near future, a technological step of introducing anisotropic materials like Carbon Fibre Reinforced Plastics (CFRP) in structural parts of cars is a possible way ahead. Though there are commercially available tools to find suitability of Fibre Reinforced Plastics (FRPs) and their orientations, they depend on numerical optimization and complexity increases with the size of the model.

  5. 19. Design and Evaluatoin of a Carbon Fibre Bus Body

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :David Nordin; [2018]
    Nyckelord :;

    Sammanfattning : The automotive industry is in constant development and in recent years the environmental legislations have been getting tougher. The need for lighter and stronger materials has increased according to these changes and composite materials such as carbon fibre reinforced polymers is showing potential of being a solution due to their high specific properties.

  7. 20. Development of Dynamic Test Method and Optimisation of Hybrid Carbon Fibre B-pillar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Emil Johansson; Markus Lindmark; [2017]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
