1. 21. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system

   University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

   Author : Landmér Alice; [2022]
   Keywords : Carbon fiber; cellulose; cold NaOH aq ; lignin; precursor; sodium hydroxide; solution spinning; wet spinning;

   Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE

3. 22. Study of permanent formwork made of high-performance concrete as protection of concrete with recycled aggregate

   University essay from KTH/Betongbyggnad

   Author : Eliška Kafková; [2022]
   Keywords : Fiber-reinforced concrete; textile-reinforced concrete; high-performance concrete; concrete with recycled aggregate; fiber reinforcement; textile reinforcement; carbon footprint;

   Abstract : The production of concrete remains one of the highest CO2 producers. It consumes alarge number of primary sources of raw materials. One way to reduce emissions and rawmaterials consumption is by applying more recycled aggregates. READ MORE

4. 23. Additive Manufacturing of Self-Sensing Materials

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Benyam Angeria; [2022]
   Keywords : Additive manufacturing; continuous carbon fibre; self-sensing; non-planar;

   Abstract : A self-sensing material can not only carry a load but can also provide data aboutthe load and stress it’s being subjected to. Traditional additive manufacturing haslimited capabilities in producing self-sensing material. READ MORE

5. 24. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : William Tönnberg; [2022]
   Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

6. 25. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

   University essay from KTH/Lättkonstruktioner

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

   Abstract : 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. READ MORE
