  1. 6. Synthesis and characterization of lactic acid-based elastomers

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Afsaneh Makhdoumi; [2023]
    Keywords : Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

    Abstract : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

  3. 7. Production of textile fibres from filamentous fungi grown on apple pomace : invertase pre-treatment

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Sofia Berg; [2023]
    Keywords : apple pomace; invertase; fibres; filamentous fungi; dry gel spinning;

    Abstract : In this work Rhizopus Delemar was grown on an apple pomace medium, a waste product from the juice industry. The apple pomace was pre-treated with the enzyme invertase to hydrolyse the sucrose available in the waste to glucose and fructose, which are digestible by the fungus. READ MORE

  4. 8. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Sundmark; [2023]
    Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

    Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

  5. 9. Characterisation of an Additively Manufactured Self-Sensing Material Using Carbon Fibre Sensors

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Alain Williamson; [2023]
    Keywords : Additive Manufacturing; Self-Sensing Material; Carbon Fibre Sensors; Structural Health Monitoring; Space Applications; 3D-Printed Continuous Carbon Fibre Filament; Strain Sensor; Mechanical Properties; Electromechanical Properties; Tensile Strength; Failure Strain; Base Resistance; Gauge Factor; Linearity; Systematic Literature Review; Material Selection; Mechanical Design; Material Development; Feasibility Study;

    Abstract : Increasing demand for structural health monitoring in space highlights the need to make the creation of these systems more accessible. This study investigates the potential of additive manufacturing to achieve this goal by characterizing a self-sensing material made of a commercially available 3D-printed continuous carbon fibre filament.

  6. 10. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Felix Hansen; Mathias Berglund; [2023]
    Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

    Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE
