  2. 21. Enabling Automation of Composite Manufacturing through the Use of Off-The-Shelf Solutions

    Author : Andreas Björnsson; Kerstin Johansen; Mats Björkman; Magnus Burman; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Composite materials offer an appealing combination of low weight and high strength that is especially sought after in high-performance applications. The use of composite materials has and is continuing to increase, and the use of the material has been shown to provide substantial weight savings in for example aircraft design. READ MORE

  4. 22. Towards defect free forming of multi-stacked composite aerospace components using tailored interlayer properties

    Author : Per Hallander; Malin Åkermo; Pascal Hubert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Fibre; Composites; Prepreg; Forming; Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : Use of lightweight materials is an important part of reduction of fuel consumption by commercial aircraft. A considerable number of structural aircraft parts are therefore built of thin layers of epoxy pre-impregnated carbon fibres stacked to laminates. READ MORE

  5. 23. Experiments and Modelling of Composite–Aluminium Bolted Joints

    Author : Hannes Wemming; Zlatan Kapidžić; Stefan B Lindström; Lars Johansson; Stefan Hallström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The aeronautical industry has always strived towards weight-efficient structures since they improve aircraft performance, enable more fuel or payload, reduce cost of manufacturing and operating the aircraft, and reduce the fuel consumption and emissions. Modern airframes are often built in materials with high strength-toweight and stiffness-to-weight ratio, such as aluminium or fibre composites. READ MORE

  6. 24. Tools for ultrasonic characterization of layered media

    Author : Fredrik Hägglund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : Many industries are dealing with composite materials and multi-layered structures of various materials. Errors in the manufacturing process may lead to defects in the final product, and hence, avoiding imperfections is crucial. The importance of repeated quality assurance online is therefore essential during the process. READ MORE

  7. 25. Ultra Thick Laminates for Compact Load Introduction Fittings

    Author : Kristian Zimmermann; Dan Zenkert; Stefan Hallström; Robin Olsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Composites are increasingly often used for thick and compact structures with the clear aim to reduce the overall weight and cost of an aircraft. But classic applications of composites are thinner structures with limited out of plane loads. READ MORE
