  4. 3. Characterization of injection molded polymers – from conventional to wood-based thermoplastics

    Författare :Linnea Björn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAXS; WAXS; melt processing; injection molding; Hierarchical Materials; Polyethylene; Dialcohol cellulose;

    Sammanfattning : The success of polymers products is associated with the melt processability, which allows to create products with complex shapes at a low cost. One of the most widely used processing techniques utilizing melt processability is injection molding, where a polymer is heated until it flows into a mold under pressure. LÄS MER

  5. 4. Polymer-Based Micromachining for Scalable and Cost-Effective Fabrication of Gap Waveguide Devices Beyond 100 GHz
