  1. 1. 4-Point Bending of Composite Laminates for FEM/FEA Validation

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Pierce Cashin; [2023]
    Nyckelord :composites; 4-point bending; fiberglass; sandwich panel;

    Sammanfattning : When designing structures and vehicles using composite materials, engineers need access to critical information regarding the composite materials in question. This information describes the strength, stiffness, failure mode, and other variables that can be used to properly determine how a structure will perform while undergoing various loads and effects.

    Sammanfattning : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. LÄS MER

  4. 3. Alternativ material för armering i betongkonstruktioner : Användning av glasfiberarmering istället för stålarmering i grundplatta

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Habib Marefat; Naim Kastoune; [2023]
    Nyckelord :GFRP; FRP; CO2e; armering; stålarmering; Eurokod; hållbarhetsmål;

    Sammanfattning : Purpose: This study aimed at conducting a case study to compare the differences in reinforcement quantity, sustainability goals, and emissions in a concrete slab between fiberglass reinforcement and steel reinforcement. Method:  To calculate and study the amount of reinforcement and emission values for the different materials, a case study was made on a concrete slab for an industrial single-story building with presented dimensions from the structural engineering company Bjerking AB.

  5. 4. Green Raven Structural Design : Optimization of Internal Structure for Blended Wing Bodies

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Oscar Ehrler; Anton Holmén; [2022]
    Nyckelord :UAV; Blended wing body; BWB; wing structure; Scots pine; Fiber reinforced plastic; FRP; Off axis loading of fiber reinforced plastic; wing mount;

    Sammanfattning : The student inclusive Green Raven project of the KTH-Aero faculty requireda small blended wing model of their new flying wing design. The small scalemodel will be used for various flight tests. The goal of this specific project was tocreate an internal structure for the small scale model, including an outer shell. LÄS MER

  7. 5. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Luis Alfonso Penela Guerrero; [2022]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Sammanfattning : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. LÄS MER
