  1. 16. Development of protecting coatings for composites in an aero-engine

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Julien Mertz; [2021]
    Keywords : composites; coatings; aerospace; aero-engine; lightning strike; fire; erosion;

    Abstract : Carbon fibre reinforced polymer (CFRP) composite materials exhibit high specificstrength and stiffness therefore they can be a lightweight alternative to metalliccomponents for the front section of an aero-engine. Despite the benefit of CFRP composite materials for aero-engine applications, there arealso new challenges due to their inherent properties compared to conventionalaerospace metallic structures, such as a lower erosion resistance, poor thermalresistance, and poor electrical conductivity.

  3. 17. Sustainable polymer-tribology : Developing novel multiscale thermoplastic composites using recycled high-performance fibers

    University essay from Luleå tekniska universitet/Maskinelement

    Author : Alejandra Marcela Ventura Cervellón; [2021]
    Keywords : Tribology; Carbon Fibers; Recycled Carbon Fibers; Circular Economy; Composite; UHMWPE; Ultra High Molecular Weight Polyethylene;

    Abstract : The transition to a Circular Economy scheme that enables a more efficient usage of the resources is one of the most pressing needs in our society. From the industrial perspective this has been translated into new design philosophies and the search for more efficient systems. READ MORE

  4. 18. Tribological behaviour of metal sulfides UHMWPE composites in dry lubrication

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

    Author : Bruno Pizone Vaz; [2021]
    Keywords : Polymer composites; polymer tribology; dry lubrication; UHMWPE; metal sulfides; tribology;

    Abstract : The increasing worldwide demand for more eco-friendly materials with improved tribo- logical properties has expanded the interest in research on polymer as an alternative for conventional metal/metal contacts under dry lubrication. Specifically, UHMWPE, a semi-crystalline polymer, has shown interesting tribological properties for low demanding applications, allied with excellent recyclability, manufacturability and low cost.

  5. 19. Viability of PEEK for high-temperaturemicrovascular composites manufacture

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Yago Domínguez Muñoz; [2021]
    Keywords : Materials; composite; microvascular; PEEK; high-temperature;

    Abstract : Microvascular composites are materials with an inner hollow network which allows thecirculation of fluids. This functionalizes the composite materials, giving them furtherapplications such as self-healing or active cooling. READ MORE

  6. 20. Accelerated aging of cellulose-based composites in different climate environments : A project provided by Biofiber Tech Sweden AB

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Karin Dungner; Ebba Eskner; Amanda Holst; Nina Petersson; Maria Pokosta; John Eric Roos; [2021]
    Keywords : Cellulose; Composites; Accelerated aging; Tensile testing; Color intensity; Polymer; Climate chamber; LDPE; Cellulosa; Kompositer; Accelererad åldring; Dragprov; Färgintensitet; Klimatkammare; Polymer; LDPE;

    Abstract : This paper reviews the effects of accelerated aging with increased humidity and temperature on cellulose-based composites. The composites consist of a matrix of plastic reinforced with cellulose fibers. The company Biofiber Tech Sweden AB provided four different composites and a conventional polyolefin as reference.
