  1. 21. Migration of Xenoestrogens from Plastic Food Containers during Cooking

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : David Vigren; [2015]
    Keywords : Xenoestrogens; toxicology; ER-Calux assay; oestrogenic additives in thermoplastics;

    Abstract : Xenoestrogens are compounds, foreign from the body, that can enter cells and interact with the estrogen receptors (ER) to produce an estrogenic response. Many additives used in plastics are compounds with estrogenic activity. Some of these additives are known to slowly leach from the plastics. READ MORE

  3. 22. Technical Analysis of Flax Fiber Reinforced Polypropylene : Prerequisites for Processing and Recycling

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Josephie Mattsson; [2014]
    Keywords : biocomposites; natural fiber reinforced thermoplastics; flax fiber reinforced polypropylene; coupling agent; MAPP; reactive filler; CaO; adhesion; Mechanical properties; compounding; injection molding;

    Abstract : Nowadays, when environmental concerns are becoming increasingly important are there great interest in natural materials and recyclability. The possibility of reusing materials with maintained mechanical properties are essential for sustainability. READ MORE

  4. 23. The development of a technical costmodel for composites : Adapted to the automotive industry

    University essay from KTH/Lättkonstruktioner

    Author : Mathilda Karlsson; [2013]
    Keywords : ;

    Abstract : Composites are light, durable and can be designed to have mechanical properties rivaling those of steel. In order to use composites in more cost-sensitive fields their manufacturing-cost must decrease. One way of decreasing this cost is to manufacture larger volumes. READ MORE

  5. 24. Investigation of Mechanical Properties of Thermoplastics with Implementations of LS-DYNA Material Models.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Peter Appelsved; [2012]
    Keywords : Glass-fiber reinforced thermoplastics; polyamide; Hill’s plasticity criterion; strain recovery; cyclic loading; cyclic softening; compression strength; 3 point bend test; LS-DYNA;

    Abstract : The increased use of thermoplastics in load carrying components, especially in the automotive industry, drives the needs for a better understanding of its complex mechanical properties. In this thesis work for a master degree in solid mechanics, the mechanical properties of a PA 6/66 resin with and without reinforcement of glass fibers experimentally been investigated. READ MORE

  6. 25. Hybrid Joining of Aluminum to Thermoplastics with Friction Stir Welding

    University essay from KTH/Materialvetenskap

    Author : Wallop Ratanathavorn; [2012]
    Keywords : friction stir welding; hybrid welding;

    Abstract : Hybrid structures including aluminum-thermoplastic and aluminum-reinforced thermoplastic composite are increasingly important in the near future innovations due to its lightweight and high strength-to-weight ratio. A critical point for metal-polymer application is that sound joining of these materials is difficult to achieve owing to a large difference in surface energy and dissimilar structure between metal and polymer.
