  2. 1. Testing and analysis of composites with 3D woven reinforcement

    Author : Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D weave; finite element; manufacturing; yarn path; weaving; failure criteria; mechanical testing; 3D väv; finita element; tillverkning; trådbanor; vävning; brottkriterier; mekanisk provning; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. READ MORE

  5. 3. 3D-woven Reinforcement in Composites

    Author : Fredrik Stig; Stefan Hallström; Dan Zenkert; Andrew Long; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Composites made from three-dimensional (3D) textile preforms can reduce  both the weight and manufacturing cost of advanced composite structures  within e.g. aircraft, naval vessels and blades of wind turbines. READ MORE

  6. 4. Reversed Crafting

    Author : Karin Peterson; Hanna Landin; Högskolan i Borås; []
    Keywords : HUMANIORA; HUMANITIES; Reversed crafting; non-woven dress; formable weave; moulding dress; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Abstract : Reversed Crafting is an inquiry that aims to investigate alternative methods of form giving and manufacturing and their aesthetic consequence for dress. It is a practice-led venture that explores alternative materials and mediums through digital and analogue tools, rethinking what dress can be if not relying on currently dominant processes of form-giving and production.

  7. 5. Design and Characterization of Functional Structures for Electromagnetic Waves

    Author : Andreas Ericsson; Teoretisk elektroteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic scattering; functional structure; circular polarization selective structure; reflector antenna; electromagnetic absorber; radar cross section; compressive sensing; triaxial weave; homogenization; physical optics;

    Abstract : This dissertation deals with design and characterization of functional structures for scattering of electromagnetic waves. An abundance of these structures can be found in nature, such as the structural coloration in the feathers of a peacock, the scales of butterflies and the shell of scarab beetles. READ MORE
