  1. 1. Compression moulding of SMC : experiments and simulation

    Författare :Jimmy Olsson; Daniel Ståhlberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER

  3. 2. Compression moulding of thermoplastic composite sandwich components

    Författare :Malin Åkermo; KTH; []
    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.

  4. 3. Fibre orientation and rheological behaviour in compression moulding

    Författare :Fredrik C Vahlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Compression moulding is a common manufacturing process for composite materials. In order to better predict the processing and performance of components, simulation tools are becoming more important. In this thesis the behaviour of the compression moulding raw material has been studied to provide a platform for better simulations. LÄS MER

  5. 4. Towards 3D modelling of Compression Moulding of SMC

    Författare :Gustaf Alnersson; Staffan Lundström; Anna-Lena Ljung; Rickard Östlund; Yvonne Aitomäki; Malin Åkermo; Patrik Fernberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The automotive industry is facing ever increasing demands for reduced emissions, and lightweight solutions are thusly required. One field that has significant potential in this regard is composite materials, which can offer a good combination of weight reduction and mechanical properties. LÄS MER

  7. 5. Compression Moulding of SMC, Visualisation and Inverse Modelling

    Författare :Torbjörn Odenberger; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Before presenting the Sheet Moulding Compound (SMC) process, which is the primarily focus of this work, a literature survey is carried out to deal with fibre reinforced polymer composites in general. Then the first part of this work is presented and is primarily focused on experimental visualisation of the flow during mould closure of SMC. LÄS MER
