N2 - Carbon-carbon silicon carbide (C/C-SiC) composite plates were manufactured based on triaxial and biaxial braided fiber preforms. The liquid silicon infiltration (LSI) method was used to achieve the SiC matrix. In a first processing step intermediate modulus carbon fiber (T800 12k) preforms were manufactured via braiding technique in ±45° and ±75° fiber orientation and an optional 0° orientation. In the next step the fiber preforms were processed to carbon fiber reinforced plastics (CFRP) by warm pressing (using phenolic resin) and by resin transfer molding (RTM, using aromatic resin), respectively. The CFRP have a fiber volume content of about 60 percent. The main objective of this work was to investigate the mechanical properties under tensile and bending mode at room temperature depending on fiber orientation and processing route. The change in fiber orientation as well as the influence of triaxial fiber preforms in contrast to biaxial fiber performs will be discussed. The use of different CFRP process techniques resulted in different final matrix structures and therefore in different microstructures of the resulting C/C-SiC composites which will be compared based on CT and SEM analysis.
