  1. 1. Simulation of load capacity of 3D printed concrete patterns

    Master-uppsats, KTH/Betongbyggnad

    Författare :Magnus Burton; Karolina Näsén; [2022]
    Nyckelord :;

    Sammanfattning : Three-dimensional concrete printing (3DCP) is a technology which has rapidly developed in recent years. The technology is based on a layer-by-layer technique where models are designed in a 3D software program and printed by a robot. Unlike conventional concrete, 3DCP has stricter material requirements due to the absence of formwork. LÄS MER

  3. 2. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Rasmus Fredheim; [2021]
    Nyckelord :;

    Sammanfattning : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.

  4. 3. Warpage Prediction of Electronic Underfill Components During Curing

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :David Lindblom; [2021]
    Nyckelord :Warpage; viscoelastic;

    Sammanfattning : To ensure the shelf life of a semiconductor, the integrated circuits are usually embedded in an epoxy molding compound (EMC) to shield it from stress and corrosion. The EMC is a viscoelastic material and is categorized as a thermoset. Working with viscoelastic material appose a challenge due to the cure-induced warpage. LÄS MER

  7. 5. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mercedes Amelia Bettelli; [2020]
    Nyckelord :Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Sammanfattning : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. LÄS MER
