  1. 1. Compression moulding of thermoplastic composite sandwich components

    Detta är en avhandling från Institutionen för flygteknik

    Författare :Malin Åkermo; [1999]
    Nyckelord :;

    Sammanfattning : The thesis investigates various aspects of compressionmoulding of sandwich components with thermoplastic-basedcomposite faces and thermoplastic or thermoset core.Compression moulding of glass/polypropylene (PP) faces toexpanded PP core is initially experimentally investigated usinga statistical experimental design approach.

  2. 2. Processing of self-reinforced poly(ethylene terephthalate) composites for automotive applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Lars Jerpdal; Malin Åkermo; Hans-Peter Heim; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The vehicles of the future must have less negative environmental impact during their use phase than the vehicles of today in order to avoid major climate change on earth. Consequently electric vehicles are currently under development with the purpose of reducing CO2 emissions when the vehicle isdriven. LÄS MER

  3. 3. Cost Optimization of Aircraft Structures

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER

  4. 4. Deformability of unidirectional prepreg materials

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ylva Larberg; Malin Åkermo; Patrik Fernberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prepreg; deformability; carbon composite; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning :  To reduce cost of structural composites the development of more efficient manufacturing methods is of great interest. Sheet forming of thermoset prepreg, also known as hot drape forming, has been a promising manufacturing method for decades. An automatic tape layer (ATL) can be used to perform the lay-up in an efficient way. LÄS MER

  5. 5. Forming of stacked unidirectional prepreg materials

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ylva Larberg; Malin Åkermo; Dan Zenkert; Kevin Potter; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - Production; SRA - Produktion;

    Sammanfattning : To reduce cost of structural composites, the development of more efficient manufacturing methods is of great interest. An automatic tape layer (ATL) can be used to perform the layup in an efficient way for flat sheets and the second step is by pressure forming the prepreg stack onto a given mould. LÄS MER
