  1. 1. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers University of Technology; []
    Keywords : dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

    Abstract : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. READ MORE

  2. 2. Thiol−ene Coupling of Renewable Monomers : at the forefront of bio-based polymeric materials

    Author : Mauro Claudino; Mats K. G. Johansson; Mats Jonsson; Anna Wistrand; Sven Göthe; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; monounsaturated fatty-acids; renewable resources; cis trans-isomerization; photopolymerization; networks; polyesters; thermal viscoelastic properties; thin-films; unsaturated macro lactones; coatings;

    Abstract : Plant derived oils bear intrinsic double-bond functionality that can be utilized directly for the thiol–ene reaction. Although terminal unsaturations are far more reactive than internal ones, studies on the reversible addition of thiyl radicals to 1,2-disubstituted alkenes show that this is an important reaction.

  3. 3. Fatigue of Asphalt Mixes - Theory of Viscoelasticity and Continuum Damage Mechanics Applied to Uniaxial Fatigue Data from Laboratory Tests

    Author : Richard Nilsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; viscoelastic; Fatigue; deterioration models; Continuum Damage Mechanics; laboratory test; uniaxial; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : The advance of analytic (mechanistic) design methods increases the need for fundamental material properties. Fatigue cracking due to traffic loading, in combination with permanent deformation (rutting), thermal cracking, irregularities, frost heave and reflective cracking are some of the major criteria used when designing an asphalt concrete pavement.

  4. 4. Thermal issues in thermoplastic composites manufacturing

    Author : Andreas Trende; KTH; []
    Keywords : ;

    Abstract : Heat transfer in thermoplastic composites duringmanufacturing is treated both numerically and experimentally inthis thesis. The related issues crystallization kinetics,residual stresses, and geometrical changes are alsoinvestigated. READ MORE

  5. 5. Thermal crack estimation in early age concrete : models and methods for practical application

    Author : Mårten Larson; Luleå tekniska universitet; []

    Abstract : Control of thermal cracking in young concrete is of great importance to ensure a desired service life time and function of a structure. Making reliable thermal stress estimations, and thereby conclusions about cracking risks, involves advanced modelling of material properties and structural restraint. READ MORE
