4. 13. 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
