  1. 6. Atoms in Lithiated Carbon Fibres

    Författare :Marcus Johansen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium insertion; atom probe tomography; synchrotron hard X-ray photoelectron spectroscopy; energy storage; carbon fibres; Auger electron spectroscopy; microstructure; heteroatoms; multifunctional composites;

    Sammanfattning : Carbon fibres are key constituents of structural batteries, in which electrochemical energy storage and mechanical load bearing are merged in one multifunctional device. Here carbon fibres simultaneously act as structural reinforcement by carrying load and as battery electrode by hosting lithium (Li)-ions in its microstructure. LÄS MER

  3. 7. Towards defect free forming of multi-stacked composite aerospace components using tailored interlayer properties

    Författare :Per Hallander; Malin Åkermo; Pascal Hubert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Fibre; Composites; Prepreg; Forming; Flyg- och rymdteknik; Aerospace Engineering;

    Sammanfattning : Use of lightweight materials is an important part of reduction of fuel consumption by commercial aircraft. A considerable number of structural aircraft parts are therefore built of thin layers of epoxy pre-impregnated carbon fibres stacked to laminates. LÄS MER

  4. 8. X-ray computer tomography based numerical modelling of fibre reinforced composites

    Författare :Robert Auenhammer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray computer tomography; Finite element modelling; Segmentation; Composites;

    Sammanfattning : Non-crimp fabric reinforced polymers are commonly used to manufacture the load carrying parts in wind turbine blades. Since wind turbine blades have a large material usage, the favourable stiffness to price ratio of non-crimp fabric reinforced polymers is highly attractive for manufactures. LÄS MER

  5. 9. Advancing prospective life cycle assessment -Experiences from guiding carbon fibre composite development

    Författare :Frida Hermansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate impact; Life cycle assessment; prospective; carbon fibre composites; energy use;

    Sammanfattning : Life cycle assessment is a powerful tool for quantifying the environmental impacts of goods and services. While most easily done for well-defined and known product systems, there is also a need for a prospective (that is, a future-orientated) approach to assessing developing technologies. LÄS MER

  7. 10. Methods for efficient modelling of progressive failure in laminated fibre-reinforced composites

    Författare :Johannes Främby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composites; Progressive failure; Crash simulation; Adaptive modelling;

    Sammanfattning : To meet increasing demands on reduced CO2 emissions, the automotive industry is currently very active in research to reduce vehicle weight by incorporating laminated composites (primarily carbon fibre-reinforced polymers) into structural components. Historically, composite materials have mainly been used in the aerospace industry, whereby CAE-based design and development tools for composite structures have been developed primarily to the specific needs and requirements in this industry.
