Mechanical and Microstructural Characterization of C/C‐SiC Manufactured via Triaxial and Biaxial Braided Fiber Preforms

Two thermoplastic matrices, polyetheretherketone (PEEK) and polyetherimide (PEI), are examined in this work in terms of their suitability as carbon precursors for C/C‐SiC composites. The carbon fibers are pretreated between 400 and 1600 °C in nitrogen atmosphere to modify the surface functionality, which was characterized with XPS. An analysis of the C/C‐SiC composition shows an increasing SiC content as a function of the increased fiber pretreatment temperature and the polymer precursor. Bending tests of C/C‐SiC composites exhibit enhanced fiber‐pull‐out effects at a fiber pretreatment temperatures from 400 to 800 °C.
