  1. 1. Continuous Fibre Reinforcements in Injection Moulded Composites

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Erik Björkqvist; [2023]
    Nyckelord :Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

    Sammanfattning : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. LÄS MER

  3. 2. Robust and Biocompatible Bonding of Hybrid Microfluidic Devices Using Off-Stoichiometric Thiol-ene Thermosets

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Peter Harris; [2023]
    Nyckelord :OSTE; OSTE ; Microfluidics; Thermoset; Bonding; Thermoplastics; Biocompatibility; OSTE; OSTE ; Mikrofluidik; Härdplast; Binding; Termoplaster; Biokompatibilitet;

    Sammanfattning : Some of the major obstacles the microfluidics industry has yet to overcome in order to facilitate large scale manufacturing of devices are costly back-end processes. Among these, bonding presents some of the most obvious difficulties and is often associated with structural deformation and surface modification. LÄS MER

  4. 3. Bio-based resins for digital light processing : Mechanical and degradable properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Moa Eklund; Amanda Olofsson Ribrant; [2023]
    Nyckelord :Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

    Sammanfattning : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

    Nyckelord :vanillin; vitrimer; imine; resin; dynamic covalent bonds; biobased thermoset; photocuring; chemical recyclability; self-healing; digital light processing DLP ; 3D-printing; vanillin; vitrimer; imin; resin; dynamiska kovalenta bindningar; biobaserad härdplast; fotohärdning; kemisk återvinningsbarhet; självläkning; digital light processing DLP ; 3D-utskrift;

    Sammanfattning : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. LÄS MER

  7. 5. Development Of Bio-Based Thermosetting Resins

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Snehaben Gaurangkumar Mistry; [2021]
    Nyckelord :Bio-based polymer; Resin; lactide; lactone; isosorbide; butanediol; polymerisation; characterisation; FTIR; NMR; TGA; DMA;

    Sammanfattning : Thermoset polymers are widely used polymers in the world, but Increase in global plastic pollution and lack of fossil fuel stimulates intense research towards environmentally sustainable materials. Bio-based unsaturated polyesters (UPs) would be an excellent solution to replace oil-based synthetic polyesters. LÄS MER
