  1. 1. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Sofia Westberg; [2023]
    Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

    Abstract : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. READ MORE

  3. 2. Continuous Fibre Reinforcements in Injection Moulded Composites

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Erik Björkqvist; [2023]
    Keywords : Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

    Abstract : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. READ MORE

  4. 3. Incorporating Flax Fiber Composites in Hypercar Panels

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hanna Öster; Sara Isorena Guðjónsdóttir; [2023]
    Keywords : sound transmission loss; coincidence frequency; sound pressure level; flax fibre; carbon fibre; ljudtransmission; koincidensfrekvens; ljudtrycksnivå; linfiber; kolfiber;

    Abstract : This thesis investigates sound transmission loss through flat finite panels using composite materials, which incorporate both carbon and flax fibres. The study wascarried out by performing FEM simulations developed and validated in steps. Thevalidation process was time-consuming but crucial in ensuring the model’s reliability. READ MORE

  5. 4. Use of Pulse Thermography for Characterization of Defects in Polymer Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Kim Klöckner; [2023]
    Keywords : NDT; Pulse Thermography; polymer composites; boats manufacturing; end-of-life structures; defect characterization;

    Abstract : In this project, the possibility of using thermography as a non-destructive testing tool in the manufacturing process of boats and to assess the quality of end-of-life composite structures has been explored. To do so, a literature surview regarding the current applications of thermography and the techniques currently used for quality control in the boats industry has been conducted. READ MORE

  6. 5. MECHANICAL PROPERTIES AND TESTING OF A HYBRID COMPOSITE MATERIAL

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : ARJUN ANIL; JEEVAN JOSEPH; [2023]
    Keywords : ;

    Abstract : A composite is a structural material that consists of two or more combined constituents at amacroscopic level and are not soluble in each other. One constituent is called the reinforcingphase and the other in which it is embedded is called the matrix. The reinforcing phasematerial may be in the form of fibres, particles, or flakes to name a few. READ MORE
