  2. 6. Structure-Control of the Rheological Behaviour of Particulate Gels

    Author : Camilla Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structure formation; potato amylopectin; structure deformation; rheology; particulate gels; image analysis; beta-lactoglobulin; fracture mechanics; microstructure;

    Abstract : The focus of this thesis is the relation between the rheological and structural properties of mixed particulate gels, based on β-lactoglobulin, determined under both dynamic and static conditions. Rheological characteristics were recorded during formation of the gels, on set gels and during deformation and fracture of the gels, using viscoelastic measurements in shear and in compression and fracture mechanics in tension.

  5. 8. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers

    Author : Giovanna Iannuzzi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PP; surface defects; flow marks tiger stripes ; ageing; Injection moulding; ABS; rheological properties; degradation; surface topography; discolouration;

    Abstract : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. READ MORE

  6. 9. Microstructure and Gelation Behaviour of High Methoxyl and Low Methoxyl Pectin Gels and their Mixtures

    Author : Caroline E E Löfgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rheology; kinetic behaviour; LM pectin; transmission electron microscopy; calcium; microstructure; gel formation; sucrose; HM pectin; pectin mixtures;

    Abstract : The objective of this thesis was to explore the functional behaviour of high methoxyl (HM), low methoxyl (LM) and mixed HM/LM pectin gels of different chemical characteristics with emphasis on microstructure and kinetic rheological behaviour. The rheological properties and the structure of pectin gel networks were investigated for pectins under different sucrose, calcium and pH conditions by the means of oscillatory measurements and transmission electron microscopy (TEM).

  7. 10. Viscous Behaviour of Fibre-filled Liquids

    Author : Mina Djalili-Moghaddam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscosity; geometry effects; short-range interactions; parallel plate; fibre suspension; normal force; cone and plate;

    Abstract : Process simulation of discontinuous fibre composites is of importance in automotive industries. The performance of a fibre composite part depends to a great extent on the fibre orientation pattern. READ MORE
