  1. 1. 3D-woven Reinforcement in Composites

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

    Sammanfattning : 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. LÄS MER

  3. 2. Macroscale Modelling of 3D-Woven Composites: Inelasticity, Progressive Damage and Final Failure

    Författare :Carolyn Oddy; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D-woven composites; Anisotropy; Damage; Inelasticity; Phase-field; Failure;

    Sammanfattning : Composites with 3D-woven reinforcement have been slowly making their way into different industrial applications. The interlacement of yarns, not only in-plane but also through-thickness, means that in many applications 3D-woven composites can outperform their laminated counterparts. LÄS MER

  5. 4. Testing and analysis of composites with 3D woven reinforcement

    Författare :Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
