Abstract

Ceramic matrix composites (CMC) are interesting materials for an increasing number of applications, not only in the aerospace industry. One major manufacturing process of these materials is the Liquid Silicon Infiltration (LSI). In this process a porous carbon/carbon (C/C) preform is infiltrated with liquid silicon to form C/C-SiC-composites. The LSI process sig-nificantly lowers component fabrication time and therefore, reduces component costs compared to other CMC manufacturing processes [1]. In the present paper a thermal fibre pre-treatment (TFP) at different temperatures was applied before manufacturing the initial carbon fibre reinforced plastic (CFRP) green body. The goal was to reduce the fibre/matrix adhesion in the final C/C-SiC. One suitable parameter for the assessment of the mechanical properties of laminated CMC is the interlaminar shear strength (ILSS). The new Double Notched Compression Shear (DNCS) test was used to evaluate the influence of the TFP on the ILSS at different stages during the manufacturing of C/C-SiC.
