    Sammanfattning : Nowadays, there is an urgent need to decrease our dependence on fossilresources and shift towards the use of renewable resources for advancingsustainable development. Utilizing renewable and bio-based raw materials,such as lignocellulosic biomass, for designing new materials is a promisingapproach to promote this objective. LÄS MER

  4. 3. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets

    Författare :Björn Voigt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melamine-formaldehyde; carbon black; phenol-formaldehyde; shungite; mechanical and electrical properties; carbon fibres;

    Sammanfattning : In view of the excellent properties of carbon fibres (CF) and the growing demand for multi-functional materials e.g., electrically conductive composites, engineering thermosets with carbon fibres are highly attractive. Similarly, electrically conductive fillers are of great importance. LÄS MER

  5. 4. Recyclable High Performance Thermosets from Biobased Rigid Building Blocks

    Författare :Yunsheng Xu; Minna Hakkarainen; Karin Odelius; Youssef Habibi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The finite petroleum resources and increasing polymer waste have given rise to concerns associated with the origin and end of life management of polymer materials. Developing biobased and recyclable thermosets is an important and still underexplored part of this process, especially as thermosets also possess inherent recycling issues caused by their crosslinked structure.

  7. 5. Bio-based Composites from Soybean Oil Thermosets and Natural Fibers

    Författare :Kayode Adekunle; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bio-based thermoset resins; natural fibres; hybrid composites; renewable resources; mechanical analysis; compression molding; lyocell fiber; Energi och material; Resursåtervinning; Resource Recovery;

    Sammanfattning : In order to reduce over-dependency on fossil fuels and to create an environment that is free of non-degradable plastics, and most importantly to reduce greenhouse gas emission, bio-based products are being developed from renewable resources through intense research to substitute conventional petrochemical-based plastics with renewable alternatives and to replace synthetic fibers with natural fibers. Many authors have done quite a lot of work on synthesizing polymers from renewable origin. LÄS MER
