  2. 1. X-ray computer tomography based numerical modelling of fibre reinforced composites

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

    Abstract : 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. READ MORE

  4. 2. Production and characterisation of pine wood powders from a multi-blade shaft mill

    Author : Atanu Kumar Das; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood is an important raw material for the manufacture of consumer products and in achieving societal goals for greater sustainability. Wood powders are feedstock for many biorefining and conversion techniques, including chemical, enzymatic and thermochemical processes and for composite manufacture, 3D printing and wood pellet production.

    Abstract : The main goal in jet engine design is to achieve light, compact and highly efficient systems while reducing the cost and design times. Traditionally, the design has been based on trial-and-error procedures, which count on the skills and experience of the designer to suggest design improvements. READ MORE

  6. 4. Water-based Tape Casting of Ceramics and Fabrication of Ceramic Laminates

    Author : Annika Kristoffersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water-based tape casting; latex binders; high solids loading; silicon carbide; colloidal stability; polyelectrolyte dispersants; alumina; ceramic laminates; rheology;

    Abstract : The objective of the work presented in this dissertation has been twofold: to develop a water-based system for tape casting and to build laminar structures from the tapes. A set of requirements on the binder was specified and latexes were identified as suitable for water-based tape casting, mainly owing to their low viscosity and high polymeric content. READ MORE
