  2. 1. Properties of solid wood : responses to drying and heat treatment

    Author : Margot Sehlstedt-Persson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : The hygro-thermal processes that wood is exposed to during drying and heat treatment lead to different reactions or responses in the wood material. The objective of this thesis has been to study the impact of different drying and heat-treatment strategies on various responses, such as strength, sorption/desorption behaviour, dimensional stability and colour changes.

  5. 3. Improved high velocity cold copaction processing : polymer powder to high performance parts

    Author : Bruska Azhdar; Sture Persson; Cornell Nicolescu; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high-velocity compaction; powder polymers; polyamide-11; relaxation assist; compactibility; relative green density; morphology; pull-out; springback; Polymer chemistry; Polymerkemi;

    Abstract : A uniaxial High-Velocity Compaction (HVC) process for polymer powder using a cylindrical, hardened steel die and a new technique with relaxation assist was tested with a focus on the compactibility characteristics and surface morphology of the compacted materials using various heights of relaxation assist device with different compacting profiles. Relaxation assist device was presented as a new technique to reduce springback, pull-out phenomenon and to improve the compaction process. READ MORE

  6. 4. Model for End of Life Treatment of Polymer Composite Materials

    Author : Anna Hedlund-Åström; Jan-Gunnar Persson; Conrad Luttropp; Sigbritt Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer composites; material recycling; energy recovery; environmental effects; recommendations; waste treatment model; Environmental engineering; Miljöteknik;

    Abstract : Because of increasing environmental demands, especially on dealing with products end of life phase, product manufacturers and designers must consider the future disposal of their products. For conventional materials like steel and aluminium well-functioning recycling methods exists. READ MORE

  7. 5. On the modular modelling for dynamical simulation with application to fluid systems

    Author : Carl-Johan Sjöstedt; Jan-Gunnar Persson; Petter Krus; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : This licentiate thesis highlights some topics on modular modelling for dynamical simulation with application to fluid systems. The results are based on experience from the development of the fuel cell component simulation environment NFCCPP. The general application is cross-enterprise simulation of technical systems.
