  1. 16. Modeling of residual stresses in dental composites

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

    Sammanfattning : In several European countries, dental composites are replacing mercury- containing amalgams as the most common restorative materials. The problems with dental composites are that they can induce pain for the patient, fracture in the tooth, and gaps between the tooth and the filling which will induce secondary caries. LÄS MER

  3. 17. Synthesis and characterisation of thermoset-layered silicate nanocomposites

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

    Sammanfattning : Thermoset-layered silicate nanocomposites are materials reinforced on a molecular scale by 1 nm-thick silicate layers of high aspect ratio dispersed in a thermoset matrix. These new materials were synthesised from unsaturated polyester and several epoxy resins (DGEBA/diamines and TGDDM/DDS) using two different approaches. LÄS MER

  4. 18. Exploring fatty acid derivatives from renewable resources as raw materials for coating applications

    Författare :Samer Nameer; Mats Johansson; Mats Martinelle; Dean Webster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; vegetable oils; birch bark; thermoset; bio-based; fatty acid; renewable resources; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In the work presented herein, epoxy fatty acid derivatives were explored in the formation of thermosets for coating applications. The epoxy fatty acid derivatives were obtained from renewable resources such as birch tree bark and epoxidized linseed oil. LÄS MER

  5. 19. Induction heating of carbon fibre reinforced polymer composites : Characterization and modelling

    Författare :Fredrik Lundström; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon fibre reinforced polymers; Induction heating; Material characterization; Thermal properties; Electrical conductivity; Numerical modelling;

    Sammanfattning : Carbon fibre reinforced polymers (CFRP) are lightweight materials with great potential due to their high strength and stiffness relative to their weight. This enables weight reduction in, for example, vehicles, which is important in reducing energy consumption. LÄS MER

  7. 20. Bio-based C-3 Platform Chemical: Biotechnological Production and -Conversion of 3-Hydroxypropionaldehyde

    Författare :Roya Rezaei; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus reuteri; 3-hydroxypropionic acid; biotransformation; Glycerol; 3-hydroxypropionaldehyde; In situ complexation;

    Sammanfattning : Demands for efficient, greener, economical and sustainable production of chemicals, materials and energy have led to development of industrial biotechnology as a key technology area to provide such products from bio-based raw materials from agricultural-, forestry- and related industrial residues and by-products. For the bio-based industry, it is essential to develop a number of building blocks or platform chemicals for C2-C6 chemicals and even aromatic chemicals. LÄS MER
