  2. 21. Exploring structural carbon fiber composites for mass-less energy and actuation

    Author : Wilhelm Johannisson; Dan Zenkert; Göran Lindbergh; Ian Bond; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : The energy consumption in transport is today a large contributor to global greenhouse emissions. One way of reducing these emissions is by electrification, which is an ongoing journey for the vehicle industry. The aeronautical industry has started investigations but are limited by the relatively low specific energy of batteries. READ MORE
