Development, Manufacture and Characterization of C/C-SiC Components based on Filament Winding

Abstract

In this contribution development, manufacture and characterization of C/C-SiC tubes based on different winding angles is described. Therefore, CFRP tubes were made by wet-winding of C-filaments using thermoset resins with high char yield and, in a second step were converted to C/C tubes via pyrolysis. Then, the porous tubes were infiltrated by liquid silicon providing C/C-SiC tubes which were characterized by their microstructure and mechanical properties. Mechanical testing was performed under tensile loading in axial and circumferential direction (burst test). In addition, a correlation of mechanical properties to the winding angle will be presented.
