  1. 16. Visualisation of composites manufacturing

    Författare :Magnus Andersson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The five papers in this thesis demonstrate five unique ways to monitor composite manufacturing. They also clarify several phenomena that take place during composite manufacturing. Of particular interest are two manufacturing methods, namely vacuum infusion (Paper A-D) and compression moulding of SMC (Paper E). LÄS MER

  3. 17. Processing and properties of glass mat thermoplastics

    Författare :Greger Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The rapid processing of glass mat thermoplastics (GMT) is well known, large complex parts can be processed in less than one minute. It is however important that the material is produced properly to avoid a reduction in mechanical properties. There are some underlying industrial questions for this work. LÄS MER

  4. 18. Developing Process Design Methodology for Investment Cast Thin-Walled Structures

    Författare :Mohsin Raza; Björn Fagerström; Mark Jolly; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innovation and Design; innovation och design;

    Sammanfattning : Components for engineering systems, such as gas turbines and jet engines operating at high temperature are usually produced in superalloys. The investment casting process is most widely used for manufacturing these components due to the ability of the process to produce parts with complex geometries to close dimensional tolerances.

  5. 19. Process development for investment casting of thin-walled components : Manufacturing of light weight components

    Författare :Mohsin Raza; Björn Fagerström; Jarfors Anders; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment casting; fluidity; thin sections; porosity; grain structure; turbine blades and Niyama criterion; Innovation and Design; innovation och design;

    Sammanfattning : Manufacturing processes are getting more and more complex with increasing demands of advanced and light weight engineering components, especially in aerospace industry. The global requirements on lower fuel consumption and emissions are increasing the demands in lowering weight of cast components. LÄS MER

  7. 20. Appearance characterisation of textured polymeric surfaces

    Författare :Ingrid Arino; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; reflectance; polymer; colour; surface texture; gloss;

    Sammanfattning : Appearance demands for industrial products are generally increasing since they are closely related to the overall quality impression. Consequently, there is a need to define appearance through its main descriptors, which are gloss, colour and surface texture, as well as the relations between them. LÄS MER
